"Angara" can be reusable

74
In the Khrunichev Center pursuant to the instructions of the President and the Government of the Russian Federation, they began to develop a reusable stage for the Angara-1.2 light-class rocket, according to News.




Experimental design work is being carried out on this subject. We carry it out with Roskosmos and Myasishchev OKB,
The General Director of the Khrunichev Center Alexey Varachko told the newspaper.

According to the newspaper, the main option considered to turn the Angara into a reusable one is the equipment of the light version of the carrier with folding wings. After launch and removal of cargo into orbit, the rocket will be able to open its wings and, like an airplane, make a soft landing at the airfield.

At the same time, other options for returning the first stage are also being studied: with the help of our own engines, like the American Falcon 9 rocket or landing with a parachute.

It is noted that the first results can be announced in the spring of 2018. By this time, the technical shape of the reusable "Hangars" will be selected.

“In 2011 – 2013, the Khrunichev Center worked on a draft design of a cruise missile unit for Angara as part of the Reusable Space Rocket System (MRKS). At the end of 2013, the Roscosmos Scientific and Technical Council reviewed the preliminary research results and confirmed the possibility of creating a reusable complex. But this project did not become successful: the cost of removing a kilogram of cargo using the MRX turned out to be higher than during a one-time flight, ”the material says.

In both cases, it was about creating a winged stage for the heavy version of the "Angara". The new development involves the addition of wings to the light version of the rocket.

The launch market for small spacecraft is promising, a similar rocket can be used on it. But everything should be carefully calculated. For such a rocket, an aerodrome, ground infrastructure maintenance and post-flight operations are necessary. Will require large expenditures for research and development work. Will the economic effect pay off all these investments due to reusability? Careful economic assessments are needed,
Ivan Moiseyev, scientific director of the Space Policy Institute, told the publication.

The Energia rocket and space corporation is developing its own version of a reusable carrier. In parallel with the design of the new medium-class missile, the Soyuz-5, the corporation is exploring the possibility of creating a modification of this carrier with a return stage.

      It is already CUT to remind starts. Not having achieved the result in one, but having mastered the budget, moving on to another - more grandiose, and meaning expensive. No, dear Sirs, let us report on the previous draft.

        The secret satellite, code-named Zuma, launched on Sunday by the Falcon 9 launch vehicle of the American company Ilon Mask SpaceX, did not reach the calculated orbit and crashed when it fell into the ocean. It is reported by Reuters.

        But, the fewer American satellites in orbit - the more money from our budget will go to medicine and education

    The news is interesting, but as usual it’s slightly incomplete. I would add the following:
    "The information of the Khrunichev Center press service was confirmed by Roskosmos and Myasishchev Design Bureau: it is noted that the first results of scientific and technical works and tests will be known in the spring of 2018. At the same time, the industrial commission will be able to familiarize themselves with the estimate of the project, which will determine level of government funding for the Angara-1.2 project. "
    So the cries for cutting the state budget are somewhat premature. In the worst case, it is an attempt to make a request for a cut.

    Let’s see what Khrunichev’s get, we have a lot of plans and promises, and when it comes to the result, either the deadlines endlessly shift the time, or the projects are canceled altogether .... I'm waiting for the Science module to be finally sent to the ISS, they’re already pulling ....

    According to Falcon 9 (Zuma launch), it’s certainly nice when everything is bad for the opponent / adversary, but failures happen for everyone, Roskosmos also had problems (not so long ago), so these are working moments. There is information that "Northrop Grumman made its own separation system for the satellite, including the adapter" and who messed up there is not clear, SpaceX or Northrop Grumman, if the reason is with the separation.

    The fact that disposable systems would become unprofitable was clear even in the days of Gagarin. Steps that are not returned separately are not an option, and most likely it will not go beyond experimental models. You need to get Myasischev projects out of storage and bring them to mind with new technologies and materials. , up to 10 tons of payload, everything is already possible.

The separation of the 1st stage of the rocket is carried out at an altitude of ~ 40 km at a speed of 2,5 - 3 km / s, which is already obvious hypersound! But the contours and configuration of the Baikal wing are uniquely subsonic ...

        There is a rotary wing. Before separation from the rocket, it is rotated along the hull, after separation, and becomes in working position.
        And if our respected space managers really worked on this return stage, and not shied away in various projects. Simply put, they did not chase the dough and did not cut it, Baikal would have already flown. It's a shame - you panim. But,
        what they chose - they chose. The result we are now observing.

      An economically unprofitable design is difficult to manufacture and maintain.

        Not the fact that it is not economically profitable. The tests were never completed. But if you look at the picture of a bunch of several Baikals and the Angara, you can see a very stable design. Stable in terms of yaw of the general missile assembly. Minimum taxiing due to rear stabilizers and vertical keels of Baikal. At launch, the rocket, in principle, should go exactly like on rails.

    KMK, the best option for a return stage would be to add shunting engines at the top of the first stage. Pieces four. Their advantage is that they will add traction at launch and will not fly with a passive load, and when they land, they simply dampen the launch vehicle to a minimum and bring the launch vehicle to the capture area for a special power belt with a special farm (or farms) above the pool.

      The grip with the “paw” is docked with a pneumatic-spring-counterweight mechanism with sufficient travel to smoothly quench speed at a distance of almost a couple of tens of meters.

        The catching of a landing rocket can be carried out using a hook and a rope. Suppose the PH has 6 pieces of vertical hooks in the upper part along the axis. The task is to catch the cable (s) under one or several hooks. It is assumed that the speed of the landing LV will not be large, and this can be confidently performed. At the start, the hooks can be bent 90 degrees and stick to the sides (they will not create significant resistance).
        Suppose we have a rectangular pool of water, in the corners of which there are towers. A cable is pulled between two adjacent towers, to the ends of which are attached 2 cables from each tower. The cable can move quickly due to changes in the lengths of the ends going to the towers, the ends of these cables are attached to devices similar to the aircraft carrier’s finishers. (Moving the aerofinisher up / down along the tower will change the length of the end.) Then there can be 4 cables, which “catch” the PH hooks, i.e. along each side of the pool. When approaching the launch vehicle with hooks, the automatics quickly orientates which cable to which initial position to install, so as not to touch the falling launch vehicle. And at some point - it quickly shifts the cables to the calculated position to grab them with hooks, but so as not to hit the sides of the launch vehicle. Further work are the air finishers. The engines are shutting down. And the pool is closed with rigid plates, on which it is already possible to smoothly lower the pH. The platform should be closed from side winds.

    are they there in ross space completely moved? or another budget to drool salivating already on the knees?

    nothing that the brainchild of the mask is designed for a very specific business plan with a very specific number of starts, and a very specific pump of loans,

    but no, let’s swell it’s not clear what a lot of money is from the budget, and the fact that this rocket will be gold and useless to anyone is not a problem, the gas and oil dollars will be thrown out of the budget, the government’s thinking is at the level of the great Papuan leaders from Africa.

    ps for systems with a return, you need either super-expensive, super-light and super-strong cases, or more efficient engines, with an insane price tag, or all together, then it makes sense.

    just that there are no breakthroughs in the structure of engines, there is a loss of technology for already made engines, with the same parsley bodies, no breakthrough technologies in Russian material science are observed, as well as new buildings.

      About the engines - Moscow. January 8. "INTERFAX-AVN - A. Lyulka Research and Development Bureau (part of the UEC) is working on a pulsating detonation engine (SDA) for advanced aviation systems," project director Alexander Tarasov told Interfax earlier.

      "The range of application of this promising engine is wide - from unmanned aerial vehicles to airplanes for various purposes. In the future, based on new technologies, engines can be created for rocket-space systems and combined power plants of aircraft capable of flying in the atmosphere and beyond," stated A. Tarasov.

      In March last year, the source of Interfax-AVN in the aviation industry announced the progress in creating a promising pulsating detonation engine. According to him, at present, the development of the engine is at the stage of research and various tests.

      "The results of the studies showed that the SDA compared to turbojet engines (TRD), which are installed on aircraft today, will have 1,5 times greater thrust and significantly, about 1,5 times, less fuel consumption. In addition, dry the mass of traffic rules is less than that of a turbojet engine, "the agency’s interlocutor said.

      According to him, during the tests it was confirmed that the engine can be turned on and off repeatedly, as well as change the operating mode, which allows you to adjust traction.

      The interlocutor of the agency said that with the work of OKB im. A. Lyulki on the promising pulsating detonation engine familiarized with representatives of industry departments and ministries, including the power block, who expressed the opinion that it is necessary to continue work in this promising direction.

      The layout of this engine design bureau them. A. Lyulki represented at the Army 2017 forum

        So far there will be no breakthrough in engines comparable to the transition from screw to turbojet, and there is no point in talking about serious changes!

    in general, it would be better if the air start was made normal, but they did not hang around with the useless hangar.

    or already torture the crown, why hangar?

    Oh, yes, we’ll just attach wings to the Angara and it will be able to land on airfields and become reusable - all for suckers, because we understand that for this you will have to re-create a rocket and spend tens of billions of rubles.

    I’m embarrassed to ask - where is a heavy rocket with 75-80 tons payload? And then I constantly hear we fly to the moon, very soon. Well, I saw the plywood layout of the Federation in Kinetics, but it looks like there isn’t even a cardboard layout of a heavy rocket.

    Gentlemen, wait a couple of years after the announcement of the launch of the reusable rocket they will announce a meteorite that has fallen on some Dzhezkazgan or Chelyabinsk. This will not be surprising against the background of many recently fallen missiles.

    Again, reusability has come into fashion. And again, we are not legislators. Well, how much can you step on the same rake? Well, with what fright can cost-effectiveness appear for the light version of the Hangar? Indeed, the reduction in the weight of the rescue and soft landing systems from heavy modifications of reusable LVs to the lungs does not go in direct proportion, but in power and only up to certain values. And the rescue system can be installed only by reducing the weight of the payload. How much will remain from 1,5 - 3,5 tons of fire trucks if the reusability requirement will force the dry weight of the URM-1 to be not less than 1 ton (the weight of the rescue and landing system + the weight of the control system + reinforcement of the URM-a structure in the places of attachment of the wing and supports chassis), and about 0,5 tons still need to leave fuel for landing (about 10 seconds of operation at 50% thrust) and also take this weight away from the weight of the payload? A rough estimated calculation gives a value of PN 0 - 1,5 tons. Which requires to keep the efficiency of use at least 2 times to increase the frequency of launches. If we conditionally accept the average number of launches of the disposable Angara 1.2 20 per year, then the reusable Angara 1.2 will need to be launched weekly (and this is still a rather bold assessment, I met the opinion that for the payback of reusable missiles at least 100 launches per year should be done). Will our Roskosmos be able to work in the mode of such a conveyor?

    Another "our answer to Chamberlain" - the Mask!
    Of course, with a decent lag.
