Contract for the development of a draft design of the space rocket complex of the super-heavy class
The first details of the future space rocket complex of the super-heavy class appeared (KRK STK). On the site of state procurement on March 27, a contract for the creation of such a complex was published. The fact that the contract is concluded between Roskosmos and RSC Energia was announced back in February, the press service of the agency reported. But now the Internet community has opened access to more detailed information, which I will try to chew.
For a long time in the RSC Energia, the future lunar carrier was connected with the Angara. Anyway, the developers were going to devote a lot of tasks to this rocket. This launches PTK NP "Federation", interorbital nuclear tugs, the moon was to go to a heavy version of the "Angara-A5." But nothing was fated to come true. Perfectly understanding that the carrier is not suitable for carrying out the assigned tasks, Roskosmos slowly and quietly deduced it from all projects. And the projects had to be postponed until better times, until a new family of rockets was ready. By inertia, Russia began to lag behind in the creation of its superheavy complex, erroneously orienting itself for years on a pacifier. But the created reserve in creation of novelties has helped the Russian enterprises for 2-3 years completely to be reoriented.
While the Angara were still trying to reanimate the Energia, the Progress missile and space center in 2015 began working on a new missile, which was put in hopes of becoming a universal substitute for everything. Soon the space agency saw the potential of a new development and quickly transferred it to "Energia" as the parent company, and "Progress" remained co-executor. By the way, initially the new family was to take some of the developments from the offspring of Energia, but to this day it was completely abandoned due to the sudden appearance of S7 Space on the market. The space company signed a cooperation agreement with Roskosmos, and the new Soyuz-5 missile had to be recycled urgently, taking into account launches from the Sea Launch.
A few days ago, at last, the first outlines of the plan for the super-heavy complex appeared. The agency decided on its tasks and needs. And therefore, in terms of open access, the technical assignment for the SC R & D (a component part of the experimental design work) fell into it. For some reasons, I will not use snapshots of the task, but the document itself can be found on the website of state purchases and it is not hidden.Part I
What is the KRK STK. The whole complex is not only a superheavy booster rocket, but also a multitude of other components. Apart from the fact that these are production facilities and a new launch pad, STK are 3 main parts. The carrier, a new upper stage, created specifically for it, and ... an interorbital tug.Part II
The technical task itself is the development of a draft outline of the superheavy complex, which must be delivered in October 2019. The timing was stretched due to the transfer of the delivery of the draft project "Soyuz-5". In the publication Notes. The first flimsy steps of Soyuz-5 can be read in more detail about the reasons for the transfer, but in brief - the draft received many comments from the scientific and technical council of Roskosmos and representatives of S7 Space. To eliminate the defects, additional time was allocated. The project on STK, based on the steps of the new missile, also apparently decided to shift. The allocated funds amounted to 1.6 billion rubles. A third of the funding is for 2018 and another billion will be spent in 2019.Part III
The objectives of the implementation of the MF ROC are, as a matter of fact, the creation of the appearance of the complex with characteristics, the development of technological and technical solutions for the production of the complex. The main tasks are: the conclusion of a payload (payload) of not less than 80 tons per LEO (low Earth orbit) and at least 20 tons per low polar okolununnuyu orbit. Additional tasks: development of such solutions, in which a modified version of the launch vehicle will output up to 140 tons of DOE, and 27 tons, respectively, to the lunar orbit. As well as deducing spacecraft (space vehicles) and space station modules (!!!) to Mars, Jupiter and other promising for the exploration of the celestial bodies of the solar system.
Flight testing of individual components of the complex should begin in 2028th year. The place of testing and dislocation of the complex is the "Vostochny" cosmodrome.
It is finally confirmed that the launch vehicle will become an analog of Falcon Heavy in its modularity. It will be collected from the "Union-5". Modularity should be a good help, and in the TOR to the developer specifies that the carrier must understand and assemble in the shortest possible time with the start failed. The performance of the SRK SRC should be at least 2 starts a year. In this we win the United States twice. The American SLS plans to start only once a year.Part V
The development of a nuclear tug was also confirmed, which was hampered and stopped due to some problems. Now, in the terms of reference for RSC Energia, a direct instruction has been issued. Part of the complex should be such a tug. Its main task at this stage will be the transportation of goods and the Federation between the orbits of the Earth and the Moon. Since the near-moon station will be at an altitude of 70-100 thousand km, the tug will also be responsible for the delivery of spacecraft and PTK "Federation" to the polar orbit of the Moon at an altitude of only 200 km. The tug's capabilities should allow transporting up to 20 tons.
The launch from Earth will be carried out in the fairing of a new superheavy rocket, which is confirmed by my recent words - the developers could not meet the 22 tons of tugboat that Angara was supposed to take out. A new carrier can lift from 80 tons and more.
This is all that was important and interesting in the annex to the contract for RSC Energia. As cherry on the cake, in those. specification - to monitor the development and take the results of the work will be the Ministry of Defense. Therefore, no one can make any shoals. Considering that S7 plans to submit a program to accelerate the work on the inter-orbit tug at Roskosmos by the end of this year, it can be argued that the deadlines and developments are serious. In the next 10 years, astronautics will turn upside down.
