“Buran” and “Shuttle”: such different twins

When you look at the photos of the Burana and Shuttle winged spacecraft, you may get the impression that they are quite identical. At least there should be no fundamental differences. Despite the external similarity, these two space systems still differ radically.
“Buran” and “Shuttle”: such different twins

Shuttle and Buran


Shuttle - reusable transport spacecraft (MSTC). The ship has three liquid rocket engines (LRE), working on hydrogen. The oxidizing agent is liquid oxygen. A huge amount of fuel and an oxidizer is required to make an exit to Earth orbit. Therefore, the fuel tank is the largest element of the Space Shuttle system. The spacecraft is located on this huge tank and is connected to it by a piping system that supplies fuel and oxidizer to the Shuttle engines.

And still, three powerful engines of a winged ship are not enough to go into space. Two solid-fuel boosters are mounted to the central tank of the system - the most powerful missiles in stories humanity today. The greatest power is needed precisely at launch, in order to move a multi-ton ship and lift it to the first four and a half dozen kilometers. Solid rocket boosters take on 83% load.

The next "Shuttle" takes off

At an altitude of 45 km, solid fuel boosters, having produced all the fuel, are separated from the ship and parachuted into the ocean. Further, to the height of 113 km, the "shuttle" rises with the help of three rocket engines. After separation of the tank, the ship flies another 90 seconds by inertia and then, for a short time, two orbital maneuvering engines operating on self-igniting fuel are turned on. And the "shuttle" goes into work orbit. A tank enters the atmosphere, where it burns. Parts of it fall into the ocean.

Department of solid fuel boosters

The orbital maneuvering engines are intended, as can be understood from their name, for various maneuvers in space: to change the parameters of the orbit, to moor to the ISS or to other spacecraft in near-earth orbit. So the "shuttles" visited the Hubble telescope several times for service.

And finally, these engines are used to create a braking impulse when returning to Earth.

The orbital stage is made according to the aerodynamic scheme of a tailless monoplane with a low-lying delta wing with a double sweep of the leading edge and with vertical tail of the usual scheme. For control in the atmosphere, a two-section rudder on the keel (here air brake), elevons on the rear edge of the wing and a balancing shield under the rear fuselage are used. Chassis retractable, tricycle, with a nose wheel.

Length 37,24 m, wingspan 23,79 m, height 17,27 m. “Dry” weight of the device is about 68 t, take-off - from 85 to 114 t (depending on the task and payload), landing with return cargo on board - 84,26 t.

The most important feature of the airframe is its thermal protection.

In the most heat-stressed places (design temperature up to 1430º С) a multi-layered carbon-carbon composite is used. There are few such places, it is basically the sock of the fuselage and the leading edge of the wing. The bottom surface of the whole apparatus (heating from 650 to 1260º С) is covered with tiles from a material based on quartz fiber. Top and side surfaces are partially protected by low-temperature insulation tiles - where the temperature is 315 – 650º; in other places where the temperature does not exceed 370º С, the felt material covered with silicone rubber is used.

The total weight of all four types of thermal protection is 7164 kg.

The orbital stage has a double deck cabin for seven astronauts.

Upper Deck Shuttle Cabin

In the case of an extended flight program or when performing rescue operations, there may be up to ten people on board the shuttle. In the cockpit - flight controls, work and sleeping places, kitchen, pantry, sanitary compartment, airlock, operation and payload control posts, other equipment. Total enclosed cab volume - 75 cube. m, the life support system supports the pressure in it 760 mmHg. Art. and temperature in the range 18,3 - 26,6º C.

This system is made in the open version, that is, without the use of air and water regeneration. This choice is due to the fact that the duration of the shuttle flights was set at seven days, with the possibility of bringing it to 30 days using additional funds. With such insignificant autonomy, the installation of the regeneration equipment would mean an unjustified increase in weight, power consumption and complexity of the onboard equipment.

The reserve of compressed gases is enough to restore the normal atmosphere in the cabin in the case of one complete depressurization or to maintain the pressure in it 42,5 mm Hg. Art. for 165 minutes when a small hole is formed in the body shortly after the start.

Cargo compartment dimensions 18,3 x 4,6 m and the volume 339,8 cube. m is equipped with a "three-knee" manipulator with a length of 15,3 m. When you open the casement doors, the cooling system radiators are rotated with them. The reflectivity of radiator panels is such that they remain cold even when the sun shines on them.

What can the space shuttle and how does it fly

If we imagine a system assembled, flying horizontally, we will see an external fuel tank as its central element; an orbiter is docked on top of it, and accelerators on the sides. The total length of the system is equal to 56,1 m, and the height is 23,34 m. Overall width is determined by the wingspan of the orbital stage, that is, it is 23,79 m. The maximum starting weight is about 2 041 000 kg.

It is impossible to say so unequivocally about the size of the payload, since it depends on the parameters of the target orbit and on the starting point of the ship. We give three options. The Space Shuttle system is able to output:
- 29 500 kg when launching east from Cape Canaveral (Florida, east coast) into orbit 185 km altitude and 28º inclination;
- 11 300 kg at launch from the Center for Space Flight. Kennedy into orbit altitude 500 km and inclination 55º;
- 14 500 kg when launched from the Vandenberg Air Force Base (California, west coast) into a polar orbit with an altitude of 185 km.

For the shuttles were equipped with two runways. If the shuttle landed away from the cosmodrome, he returned home astride Boeing 747

Boeing 747 is taking the shuttle to the spaceport

A total of five shuttles were built (two of them died in accidents) and one prototype.

During development, it was envisaged that the shuttles will make 24 start per year, and each of them will make flights to space before 100. In practice, they were used significantly less - by the closing of the program in the summer of 2011, 135 launches were made, of which Discovery - 39, Atlantis - 33, Columbia - 28, Challenger - 25, Challenger - 10 .

The crew of the shuttle consists of two astronauts - the commander and the pilot. The largest crew of the shuttle is eight astronauts (Challenger, 1985 year).

Soviet reaction to the creation of the "Shuttle"

The development of the shuttle made a great impression on the leaders of the USSR. It was believed that the Americans are developing an orbital bomber armed with space-to-earth missiles. The sheer size of the shuttle and its ability to return cargo to Earth up to 14,5 tons were interpreted as a clear threat to the abduction of Soviet satellites and even Soviet military space stations such as Almaz, which flew in space under the name Salyut. These estimates were erroneous, since the United States in 1962 abandoned the idea of ​​a space bomber in connection with the successful development of the atomic submarine fleet and ground-based ballistic missiles.

"Union" could easily fit in the cargo compartment of the "Shuttle"

Soviet experts could not understand why we need 60 launches of “shuttles” per year - one launch per week! Where were the many space satellites and stations for which the Shuttle would be needed to come from? The Soviet people living under a different economic system could not even imagine that the leadership of NASA, which was pushing hard at the new space program in the government and the congress, was guiding the fear of being left without work. The lunar program was nearing completion and thousands of highly qualified specialists were out of work. And, most importantly, before the respected and very well-paid managers of NASA there was a disappointing prospect of parting with habitable cabinets.

Therefore, an economic rationale was prepared for the large financial benefit of reusable transport spacecraft in the event of the abandonment of disposable missiles. But for the Soviet people, it was absolutely incomprehensible that the president and the congress could spend national funds only with great regard for the opinions of their voters. In this connection, the opinion prevails in the USSR that the Americans are creating a new spacecraft for some kind of future incomprehensible tasks, most likely military ones.

Reusable spaceship "Buran"

In the Soviet Union it was originally planned to create an improved copy of the Shuttle - OS-120 orbital plane, weighing 120 tons. (The American shuttle weighed 110 tons at full load). Unlike the Shuttle, it was supposed to provide the Buran with an ejection cabin for two pilots and turbojet engines for landing at the airfield.

The leadership of the USSR armed forces insisted on the almost complete copying of the “shuttle”. Soviet intelligence was able to get a lot of information on the American spacecraft by this time. But it turned out not so simple. Domestic hydrogen-oxygen fuel rocket engines turned out to be larger and heavier than the American ones. In addition, they were inferior in power overseas. Therefore, instead of three LREs, it was necessary to install four. But on the orbital plane there was simply no place for the four cruise engines.

At the "shuttle" 83% load at the start carried two solid fuel accelerator. In the Soviet Union, such powerful solid-propellant rockets could not be developed. Missiles of this type were used as ballistic carriers of nuclear charges of sea and land-based. But they did not reach the required power very, very much. Therefore, the Soviet designers had the only opportunity - to use liquid rockets as accelerators. The program "Energy-Buran" created very successful kerosene-oxygen RD-170, which served as an alternative to solid-fuel boosters.

The location of the Baikonur cosmodrome forced the designers to increase the power of their launch vehicles. It is known that the closer the launch pad to the equator, the greater the load the same rocket can put into orbit. At the American spaceport at Cape Canaveral, the advantage over Baikonur is 15%! That is, if a rocket launched from Baikonur can lift 100 tons, then it will launch 115 tons into orbit when launching from Cape Canaveral!

Geographical conditions, differences in technology, the characteristics of the engines created and a different design approach - had an impact on the appearance of "Buran". Based on all these realities, a new concept was developed and a new OK-92 orbital spacecraft, weighing tons of 92, was developed. Four oxygen-hydrogen engines were transferred to the central fuel tank and the second stage of the Energia launch vehicle was obtained. Instead of two solid-fuel boosters, it was decided to use four liquid-fuel kerosene-oxygen missiles with four-chamber RD-170 engines. Four-chamber - this means with four nozzles. A large-diameter nozzle is extremely difficult to manufacture. Therefore, the designers go to the complication and weighting of the engine by designing it with several smaller nozzles. How many nozzles, so many combustion chambers with a bunch of pipelines supplying fuel and oxidizer, and with all the "whips." This bundle is made according to the traditional, "Royal", scheme similar to the "unions" and "vostokam", became the first step of the "Energy".

"Buran" in flight

The winged ship "Buran" itself became the third stage of the launch vehicle, like the Soyuz. The only difference is that the "Buran" was located on the side of the second stage, and the "Unions" at the very top of the launch vehicle. Thus, the classical scheme of a three-stage disposable space system was obtained, with the only difference that the orbital spacecraft was reusable.

Reusability was another problem of the Energy-Buran system. The Americans, “shuttles” were designed for 100 flights. For example, orbital maneuvering engines could withstand up to 1000 inclusions. All the elements (except the fuel tank) after the prophylaxis were suitable for launching into space.

Solid accelerator picked up by a special vessel

Solid fuel boosters descended by parachute into the ocean, selected by NASA special ships and delivered to the manufacturer where they were prevented and filled with fuel. The Shuttle itself was also thoroughly tested, prevented and repaired.

Ustinov, the Minister of Defense, ultimatum demanded that the Energy-Buran system be as reusable as possible. Therefore, the designers were forced to deal with this problem. Formally, side accelerators were considered reusable, suitable for ten starts. But in fact, this was not the case for many reasons. Take at least the fact that American boosters splashed into the ocean, and the Soviet fell in the Kazakh steppes, where the landing conditions were not as benign as warm ocean waters. Yes, and a liquid rocket, creating a more gentle. than solid. "Buran" was also designed for 10 flights.

In general, the reusable system did not work, although the achievements were obvious. The Soviet orbital spacecraft, freed from large main engines, received more powerful engines for maneuvering in orbit. That, in the case of its use as a space "fighter-bomber", gave him great advantages. And plus turbojets for flight and landing in the atmosphere. In addition, a powerful rocket was created with the first stage on kerosene fuel, and the second on hydrogen. It was just such a rocket that the USSR lacked to win the moon race. In terms of its characteristics, Energia was almost equivalent to the American Saturn-5 rocket, which sent the Apollo-11 to the Moon.

“Buren” has a large foreign presence with Shattle. Korabl poctroen Po cheme camoleta tipa "bechvoctka» c treugolnym krylom peremennoy ctrelovidnocti, imeet aerodinamicheckie organy upravleniya, rabotayuschie at pocadke pocle vozvrascheniya in plotnye cloi atmocfery - wheel napravleniya and elevony. He was able to control the trigger in a timer with a side maneuver to 2000 kilometer.

The length of the "Bourana" - 36,4 meter, wing span - about 24 meter, the height of the ship on the landing gear - more 16 meters. The standard ship mass - more than 100 tons, of which 14 tons - comes on fuel. In the harbor of Volume of cabins - more than 70 cubic meters.

For this reason, “Buren” is distinguished by a powerful heat and cure for the skin and for the formation of the normal temperature and the temperature at the time of the break in the life of the vessel during the rest.

Heat shield from xnumx Ceramic bronze has the capacity to accumulate heat, not passing it to the ship's hull. The total mass of this armor is a unit of 38 tonn.

The length of the cargo compartment "Buren" - a number of 18 meters. In its extensive cargo space, the body weight can be loaded with a weight of up to 30 tons. It was possible to dispatch large-sized space vehicles - large satellites, orbital stations. Target ship weight - 82 tones.

“Buren” equipped all over the world with unimproved systems and equipment as for the automatic, so and for the pilot. This is the best and most beautiful

Burana cabin

The main engine installation, two groups of engines for the maneuvering of the engine is located in the end of the tailpiece and in the front part of the housing.

It was planned to build a 5 orbital spacecraft. In addition to the "Buran" was almost ready "The Tempest" and almost half of "Baikal". Two more ships at the initial stage of manufacturing did not receive names. The system "Energy-Buran" was not lucky - she was born at the wrong time for her. The USSR economy was no longer able to finance costly space programs. And some rock pursued astronauts preparing for flights on the "Buran". Test pilots V. Bukreev and A. Lysenko died in plane crashes in the 1977 year, even before moving to the group of cosmonauts. In 1980, test pilot O. Kononenko died. 1988 year took the lives of A.Levchenko and A. Schukin. Already after the flight, “Burana” died in a plane crash R.Stankyavichus - the co-pilot for a manned flight of a winged spacecraft. The first pilot was appointed I. Wolf.

Not lucky and "Buran". After the first and only successful flight, the ship was stored in a hangar at the Baikonur cosmodrome. 12 May 2002 year collapsed overlapping shop in which there were "Buran" and the layout of "Energy". On this sad chord the existence of a winged spacecraft, which gave so much hope, ended.

    About information shuttles, probably two times more have been written than about Buran. And after all, Buran is by no means an exact copy of the shuttle; many unique Soviet developments were implemented in it. Well, the need for such ships and now there are great doubts, while there are no goals for what to use them, they will gather dust in hangars.

        The Shuttle and Buran are similar only in that someone in the Politburo poked at the Shuttle photo and said: "I want the same thing," and it started, they closed the spiral project,
        and rushed to create an analogue of the Shuttle, not quite understanding why we needed it. We must pay tribute to the designers, Buran did in a very short time, a ship was created from scratch in 12 years.

          And after all, "Spiral" was before!
          Work on the creation of the Spiral, including the analogues of its orbital plane, interrupted in the 1969 year, was resumed in the 1974 year. In 1976 — 1978, 7 Mig-105.11 test flights were conducted
          The head of the Spiral project was Gleb Evgenievich Lozino-Lozinsky.
          If only he wouldn’t get in the way!
          And the orbital plane, as it was called in the program, "Lapot" flew
          There was a story about how to reduce the friction of his skis on a strip of watermelons.

          Well no. The Politburo has nothing to do with it. In the USSR, the whole system didn’t work like that, no need to distort.

          The creators themselves admitted that they simply decided not to fence the garden for the first ship, but to use the achievements of the Americans, so the appearance is similar. Faster, cheaper, you can focus on more important things. In parallel, we worked on other systems that are already excellent. The funny thing is that now the Americans are already copying our achievements of that time :)

            "Appearance" is similar in that (and here you are right) because the Americans did not hide all the data on aerodynamics ... I don’t remember where, but a very, very long time ago there was an interview with one of the leading specialist designers.

          "Spiral" is still relevant today.
          About ten years ago I heard from second-hand (not first-hand) air defense specialists (during the formation of the missile defense system) that the "Spiral" could easily put up to two 30mm cannons, not to mention intelligence, navigation, maneuvering, and space-to-space missiles in the cargo hold.

This one other thing is that not everything that is better-looks more comfortable, better and safer, sorry but it was with the T-90 and Abrams, there is air conditioning and other benefits, but they have a larger dead zone, and even with a “somersault” their risk of breaking their spine is higher, so .....

        At the start, the Shuttle uses its own engines to burn fuel (carrier power is not enough), and Buran does not, take off only on Energy engines.
        The result is an undeniable advantage in the fuel supply for maneuvering in orbit, at least for a rescue operation, at least for the military.

    A remarkable fact about the landing of the “Buran.” When approaching the landing glide path, the “Buran” turned 90 g. from a given trajectory, everyone thought it was a failure, an accident was inevitable, etc., meanwhile, the ship returned to the glide path. When analyzing, it turned out that the smart automatics thus simply extinguished the excessive speed.

Strange, but equipping them should have cost a lot of money than was allocated after the "perestroika". Interestingly, the article has a photo of Buran’s empty cabin - where is “all the necessary systems”?
    Nothing was said about the stupid and shameful copying of the Shuttle form and about how and by whom this decision was made, about the closure of the "Spiral", about the origin of Energy from the lunar project.
    Strange article. Lots of details. For example: "Thermal protection of over 38 thousand tiles" (This is about Buran - it is very important!). And more surviving circumstances are lied (turbojet engine, form) or not mentioned.
    As if its author had just grabbed material from the Internet in a couple of hours and uploaded it.

      By the way, the author of the article did not mention the fact that our thermal protection exceeded the shuttle’s one, and right after landing it was possible to touch the surface of the ship without using cooling, as on the shuttle, and with regards to the liquid propellant rocket engine there is doubt that they had more power, according to the turbojet engine, yes We conceded to them. Then it confuses us that our resource was lower, sorry, but our margin of safety has always been higher, and as a result, its frequent losses in terms of mass dimensions.
      Then for what photo booths it was lead that it gives ?, all the more there are several such things as their desire for comfort and ours for maximum functionality, tea fly to work! and it’s not a fact that the cabin (situation) would not have changed during further operation, and if there was a desire, it was necessary to bring the very first shuttle cabin.

    As it turned out to be an extremely complex and unreliable system, disasters during take-off and landing. 16 people die, this is the price of its ambitiousness. To return such a huge mass from an orbit to a state of plasma is another task. It’s easier to create an enlarged one by 6-8 cosmonauts (astronauts) descent vehicle of a traditional form as it is today without any wings there. Put it into space, and already dock there to another ship, which is imprisoned for the performance of some specific tasks, and intended only for flights in outer space .... Although, again, two rockets. But I have a question: what kind of payload is in the cargo compartment of the shuttle and what prevented it from entering into orbit with a conventional rocket, is it really a Hubble? And in general, what is so valuable (weighing up to 14,5 tons) that you can return from orbit, which cannot be created on Earth, while this cargo was in orbit? Cargo, and, as I understand it, it will also be radioactive.

    The atomic engine needs to be done, space will become different with it, and all these shuttles are only for orbital tasks and are somewhat redundant, carrying excess weight into orbit - wings to go back with them, is expensive both in finance and energy

      Kir 30 December 2013 18: 57 New
      The bright memory of Academician Aleksandrov had a project for such an engine, but there seemed to be problems with the "exhaust" of radiation, and the same problems in maintenance.

        saag 30 December 2013 19: 37 New
        The exhaust is yes, but right now it seems like they are developing a megawatt class reactor to power a package of ion or plasma engines, anyway, after all, drag the reactor into orbit, can it still drag RD-0410 there?

          But this miracle should start from Earth, it’s another thing to use it in Space, and now such people fly, but look at how many problems arise after working out their resource, don’t remember how much was around one (sort of like from the Cosmos series), and here "fool" is clearly a lot more serious. Clutter Near Space ?, or create what kind of burial ground outside the Earth.

    Buran is an unusual cargo that had to be put into orbit with the help of the Energia rocket - it itself could not enter orbit. As a result, a one-time powerful and very expensive rocket launched a cargo container into orbit and burned down. What is this utter stupidity? To arrange a show in front of his people? The whole world knew the true state of affairs, and only in the USSR everyone shouted cheers. And what money is wasted? One Energy rocket cost 3-4 Soyuz rockets. Shuttle reusable system, putting itself into orbit. And where all the losses is the fuel tank.

      Yes, for reusable flights with cargo return, the Shuttle configuration is much smarter than Energy-Buran. But the Americans finally abandoned the Shuttles due to the high cost of their operation. And they were unreliable, as you know.

    The article is more or less informative in technical terms (that is, it will work for explaining the differences). I’ll only add from myself, That the main difference, in my opinion, is in a different approach to delivering goods into orbit. The American shuttle is the missile itself in essence. As for us, the shuttle is SELF CARGO for the rocket. The rocket can be used to launch OTHER goods. Because only the external resemblance is not proof of copying. Take away the “Buran” from “Energy” and it will fly. Remove the shuttle from the fuel tank and get ANYTHING at the exit. Another thing is that at the wrong time it was all born from us ...
    Sad ...

    In vain you are so peremptory. By the 80s, after the closure of the Saturn program, Americans were faced with the problem of delivering large, indivisible goods to low Earth orbits. The shuttle with its marching engines on the bird and the external tank was able to deliver only a maximum of 28 tons. With the possibility of return. There were such tasks. Well, if it was necessary, for example, to deliver 100 tons without the need to return, then they did not have the funds for such a mission. Therefore, they did not begin to build their space station. In general, for the delivery of non-refundable goods, the Shuttle turned out to be, indeed, a completely ineffective system. Overly complicated and expensive.
    But the Energy-Buran system turned out to be more multifunctional. For example, to deliver 20 tons of returned cargo, the main carrier-bird bundle could be used.
    For the delivery of 100 tons of indivisible bulky non-refundable cargo: "carrier with 4 sidewalls-side container". Which was demonstrated in one of their test flights.
    For delivery of 30 tons of indivisible non-refundable cargo: "carrier with 2 sidewalls-side container".
    Moreover, in all cases, optimal SRT was used. On the sides: Oxygen-kerosene. On the central unit: oxygen-hydrogen.
    The main achievement: the technologies of very effective rocket engines were developed. And the technology of heat-protective coatings of various types.
    Echidna replicas about the "irrational" form are "philistine conversations." It would not be so arrogant about both Soviet and American scientists. The laws of ballistics and aerodynamics are objective and the same for everyone. For the chosen mission, the form is optimal. And you can’t get anywhere from her. And the Spiral was closed, because it had fulfilled its task: it had worked out the methods and gained experience. As a result of which, by the way, the Buran form was born.
    And yet - about the reusability of the first stage. In the liquid stage, not all components are equivalent. The most expensive are the engines. It makes sense to save only them. Riveting tanks - cheaper disposable. Therefore, the rescue system was designed in such a way that the tanks played the role of a deformable damper (like hoods in modern cars). So after the necessary routine maintenance, the engines could be reused.
    So the system was conceived and implemented intelligently. It’s just that she fell under the political millstones of the collapse of the country.
    I say this first hand. In the mid-70s, I was lucky to work in Podlipki. In the Buran engine development department. It was a school for life. Thanks to Buran.
    He will still shoot!

      “So isn’t it better to withdraw 100tn of payload, rather than a dead load in the form of a Buran - since if you do not need to return, and at the same time shout -“ Reusable ship ”. You really "separate the grain from the chaff," and do not write about the "advantages" of this enormous stupidity.

    The article is not bad but suffers from incompleteness. Indicate at least some modifications in the photo. In the photo of Buran, there is clearly a modification that has never flown into space and was used only for flights in the atmosphere when working out the equipment in manual mode. By the way, they were going to call their homeland. Do not disgrace, be precise. Many people saw the Buran in the forged pieces on Baikonur and in other places. And the system was truly unique in its versatility. The shuttle was not standing nearby. One military use is worth it. Bomber .scout .fighter enemy satellite you can grab and much more. And civilian applications. And flights to the moon. Mars. launch of orbital stations. So that friends criticize and think for what.
    Happy New Year to everybody.

    What kind of question bothers me is how in such a miraculous way did the roof in the hangar collapse ??? A Soviet-built hangar, and this is not some kind of barn, but a special structure with impressive strength reserves, designed and built in compliance with all sorts of requirements for critical structures. Such a building in the Kazakh steppes will stand no worse than all the pyramids with sphinxes, and here BAM !!! and the roof collapsed and right on Buran ... ah-i-yay how unlucky ... the forests around the energy (in the photo) did not collapse, but the roof fell ...
