Angara launch vehicle family

22
In Russia, the complex tests of the Angara-A5 heavy launch vehicle launch complex have been completed. The rocket has already been removed from the launch pad at the Plesetsk cosmodrome. On this 26 November reports TASS with reference to the official representative of the troops of the East Kazakhstan region Alexei Zolotukhin. According to him, the specialists at the Plesetsk cosmodrome carried out a whole cycle of electrical tests of the booster systems and launch vehicle systems and launch equipment, they also tested the Angara launch vehicle refueling system with fuel components and checked the launch vehicle readiness for the first launch of this class of rocket.


At the moment, the Angara-A5 rocket has been removed from the launch pad of the universal launch complex of the site №35. She was taken to the assembly and test building of a special technical complex. After the completion of this procedure, the cosmodrome workers began a cycle of technological operations to prepare the rocket for the start of flight tests. The first launch of the Angara-A5 heavy class rocket is scheduled for December 25 2014 of the year (estimated launch date). Earlier, on July 9, after several transfers of launch from the Plesetsk cosmodrome, the Angara-2014PP light launch vehicle (first launch) was successfully launched.

Currently, the creation of the Angara rocket complex is one of the priority areas for the development of the Russian Plesetsk cosmodrome. It is believed that this particular complex should become part of the national system of launch vehicles, which will be based solely on the Russian scientific and industrial potential. Work on the creation of ground infrastructure facilities for the preparation and launch of Angara launch vehicles is carried out within the framework of the Federal Target Program “Development of Russian cosmodromes for 2006-2015 years”.



The Angara complex is created on the basis of a unified series of launch vehicles of the light, medium and heavy classes. These missiles will be able to put into space almost the entire range of prospective payloads in the interests of the Russian Defense Ministry in the entire required range of heights and oblique orbits. It is also important that toxic and aggressive fuels will not be used in the Angara family of missiles. According to experts, such a decision will significantly improve the environmental safety performance of the entire complex, both in the region that is directly adjacent to the launch site, and in those areas in which the detachable parts of launch vehicles will fall.

Angara launch vehicle family

The main enterprise-developer and manufacturer of the Angara space rocket complex (AAC) is the federal state unitary enterprise Khrunichev State Research and Production Space Center. State customers are the Federal Space Agency and the Ministry of Defense of the Russian Federation. The creation of the Angara CEC is a task of special state importance. Putting this rocket complex into operation will allow the Russian Federation to launch into space any devices of all types from its territory, ensuring for the country guaranteed and independent access to outer space.

The Angara cruise ship is a truly new generation of Russian launch vehicles that is built in a modular fashion. These rockets are based on two universal rocket modules (URM) equipped with oxygen-kerosene engines: URM-1 and URM-2. At the same time, the Angara family of missiles includes carriers from light to heavy classes, with payloads ranging from 3,8 to 35 tons (PH Angara-A7) in low earth orbit.



URM, working on the components of oxygen + kerosene, is an already finished design, which consists of fuel tanks and oxidizer, which are interconnected by a spacer, as well as the engine compartment. Each ECD-1 is equipped with one sufficiently powerful liquid jet engine (LRE) RD-191. This engine was created on the basis of a four-chamber engine that was used on the Energia launch vehicle and is used on Zenit launch vehicles (RD-170 and RD-171 engines). URM-2 is equipped with another main engine - РД-0124А. This is the first LRE, which appeared in our country in the post-Soviet period. It is the most highly efficient oxygen-kerosene rocket engine in the world.

In the composition of the launch vehicles of the light class "Angara-1.2" is used one URM. At the same time, the ultimate in the number of modules used is the Angara-A7 heavy booster rocket, which consists of the 7 URM. The prototype of the first stage "Angara" (URM-1) three times in 2009, 2010 and 2013 years passed flight tests as part of the launch vehicle KSLV-1 made in South Korea. The upper stage on the Angara-1.2 launch vehicle can be used in the Briz-KM upper stage, which passed flight tests as part of the Russian Rokot conversion rocket, and on the Angara-А5 carrier rocket, the upper stages are used. Briz-M "and KVTK.

Unique technical solutions and widespread use of unification allow launching of all launch vehicles of the Angara family from one launcher. In accordance with the decision of the state commission, the launch vehicle of the light launch Angar-1.2 of the first launch with a non-separable payload model successfully launched the 9 on July 2014 from the Angara launch center, located in the Arkhangelsk region on the Plesetsk cosmodrome. The first test launch of the missile was carried out by the combat crews of the Aerospace Defense Forces (ASD), as well as industrial enterprises.

Angara launch vehicle family


All prelaunch operations, the launch itself and the subsequent flight of the Angara-1.2PP rocket proceeded normally. At the same time, the Angara-1.2PP booster rocket consisted of two stages, which were created on the basis of universal rocket modules (URM-1 and URM-2), as well as a mock payload of 1,43 tons and a head fairing. Only environmentally friendly components of the fuel — kerosene and oxygen — are used in propulsion systems, the launch vehicle launch mass is approximately 171 ton.

To organize the launch of Angara missiles from the Plesetsk cosmodrome, a special complex was built. It includes a launching table (PS - 1 pcs.) - weight 1185 tons, cable refueling tower (KZB - 1 pcs.) - weight 1700 tons, a universal stand designed for assembling a space head with the Briz-M upper stage ( 1 units.) - weight over 40 tons, as well as transport and installation units for light and heavy PH (197 and 400 tons, respectively).

    And why does the 5th Angara need ventilation of the warhead, an armored fairing with rocket exhaust engines, body armor protection and advertising all this?

      And why is the 5th Angara head ventilation

      These are pipelines of a cryogenic fueling system at the launch pad.
      Armored fairing with rocket engines

      As for the reservation, there is a big question, but as for the taps, it could well be the CAC system, although it is unlikely. Perhaps just for ventilation
      body armor protection

      After all, a regime facility cannot do without the military here.
      advertising it all

      Advertising for whom and why ?! Photos that are nice to see.

        In the photo, an isothermal car is attached to the installer. It is needed to heat the head part and is used at sub-zero temperatures and if the nature of the payload being launched requires it. The fairing of the head part is unarmored and has never been so. In MIK, warmth and representatives of industry are in jackets, and combat crew in winter uniforms. Why so? This is the calculation of the installer and he must be outdoors during transportation. It is cold in the North.

        What are you going to refuel with the help of pipelines of the spacecraft thermostating system? As for booking, this is not a question; it is not there, there is no need to put it there, there is no emergency rescue system on this model. The main personnel of the Plesetsk cosmodrome are the military.

      The weight of the Soviet stations of the Salute series and the Mir (Mir 2) modules was precisely determined by the carrying capacity of the Proton launch vehicle at about 20 tons. Station modules can be made 35 tons.

        It’s possible, but to make a rocket for the sake of several modules is unprofitable, the 5th hangar can throw satellites at the geostationary station, here it is profitable to produce it in a series

          a rocket for the sake of several modules is disadvantageous

          The missiles are the same, the difference in acceleration block at A5 is “Breeze-M” or KVTK (Oxygen-hydrogen heavy class), A7 - block KVTK-A7. The difference is only in the size of the tanks, in engines and electronics they are identical.

    This is connected to the pipes of the air conditioning system of the MS - practically until the moment of launch, the specified temperature and humidity regime is provided there. And the fairing has never been "armored" - it is made of fiberglass.

      Look at the photo in the article - the welded seam, stiffening ribs on the flange, additional support for support, nozzles brought to the surface ... - this is a heavy metal structure, rather steel than aluminum and no "model" is so protected.

        Where is the weld? Steel metalwork - what are you talking about? The main material of the rocket is aluminum - magnesium alloy. Where on the surface did you see the nozzles? And for information at a height of approx. 70 km. the head fairing is thrown off by dividing into 2 equal "cotyledons" and consists of many layers of glued fiberglass. There are stiffening rings on the rocket so that you can manipulate the rocket and make it a stiffness frame.

    I have a dream to launch our rockets from India, the payload would have risen firmly. Can India offer a joint part of the space program, for example, to the Moon or a space station together. Is India interesting to afford this?

    Not so much - 35 tons for a heavy rocket. After all, there was "Energia" under 100 tons of payload. Why not rebuild this project? We don't have a super-heavy rocket. And "Energy" would be just that.

        I have not been to Roskosmos, but I think that retired warriors are in charge of everything there, since the heads of state since Perminov were from the space forces. And after watching the report from the "free" in general, the entire headquarters of "Plesetsk" shed tears, only in a civilian one. Only these comrades, for the most part, do not dragged too much into the technical features of spacecraft and launch vehicles.

      Energy is an insanely expensive project. There are no spacecraft with mass for this rocket. To prepare the launch pad, the "hangars" used the Zenit launch table, which had not been completed since Soviet times, and tormented it for many years (the first launch was planned for 2000). And if you take everything else, then there will be such a nightmare that you shouldn't even think about it.

    In the text: "exclusively on the Russian scientific and industrial potential"
    And on the poster it is so very careful: "Designed and manufactured entirely in Russia"
    I have no doubt in the design, a really necessary and good project, but the potential is not true. It would be true if they put a comma and wrote:
    "Designed and manufactured entirely in Russia, FROM RUSSIAN COMPONENTS AND MATERIALS"

    It’s good that not all plans are voiced. Before putting the real module on the rocket, you need to run everything on mock-ups. The cost of a real module, depending on the purpose, can be sky-high. Risk should be minimized. Even the Lord God did not give a 100% guarantee creating a man.

    There is such info on the tactical and technical component.
    Angara-5 will raise 25,8 tons by 200 km (6,6 per GPO) already in December this year, after adding another 2-x universal missile modules (URM) to the "designer" in the spring, 2015 will deliver 35 tons (12,5 to GPO, the rocket is already at the assembly) and set a world record, and in 2016 the Ministry of Defense will launch it with 50 tons (19 tons at GPO).
    A maximum of fifty tons is not bad. Western competitors will be tucked into any belt.
    What is even more valuable - the Angara constructor for basic technologies provides for its use in a manned version, which can be called breakthroughs in world cosmonautics. Manned ships have always been designed as separate projects according to completely different standards that are not compatible with trucks. Since 2018 of the year, Roscosmos plans to begin the practical implementation of rocket launches with a team of astronauts, compared to the Soyuz that have performed this function for the last decades, the delivery and return of people to the ISS will be cheaper by 25-30%, which is about 10 million dollars for each walker. " In 2019, the "Angara" must fly to the moon, and in 2022 - to Mars. True, these are not yet approved plans, but technical prospects that are already in the project. “Today, he was preparing for Plesetsk as a truck, but now instructions have been given and the question is being worked out that at Vostochny the task of a manned launch will be solved. Because there is everything for this. There are procedures related to the fact that flight qualification is needed, responsibility is much higher, therefore there are procedures by which a rocket receives flight qualification for manned launches. And the first - it should run in a cargo version ”,
    A project with a good foundation, with which you can congratulate us.drinks

    But can a heavy hangar be loaded onto a carriage, some kind of installation. One URM has to be loaded onto an oversized car and transportation problems arise
