Progress Rocket and Space Center (Samara, is included in the state corporation “Roskosmos”) completed a number of static tests of the fuel tanks of the first stage of the prospective carrier rocket “Soyuz-5”. During the tests of prototypes of the oxidant tank, the stated strength and rigidity of the structural elements was confirmed.
For this purpose, the design of one of the two prototypes of the oxidant tank was brought to the destruction of the internal test pressure. The test result confirmed the correctness of all design solutions to develop the upper and bottom of the tank and their docking to the case. The next stage of work will be dynamic vibrational tests, which will be held at the Central Research Institute of Mechanical Engineering (TsNIIMASH, is included in the state corporation “Roskosmos”) in the city of Korolev Moscow Region.
Tanks for the Navy-5 missile tanks will be made for the first time from the new aluminum alloy 1580. The use of this material with increased strength properties allows you to increase the removable weight of the useful cargo by several hundred kilograms.
In the production of the Soyuz-5 missile, a new technology is used for domestic rocket industry – welding with stirring with stirring. Equipment that performs robotic friction welding with stirring develops and manufactures CJSC “Cheboksar enterprise” Sesby “.
In 2019, the Industry Development Fund provided the RCC “Progress” preferential loan on a special program “Conversion”. The funds are aimed at creating unique equipment for the production of the “Soyuz-5” missile.
Soyuz-5 rocket – a Russian two-stage rocket carrier of the middle class of increased load capacity (the mass of the payload deposited on the low near-earth orbit – 17 tons) is developed and manufactured in the RCC “Progress” in the city of Samara. The chief designer of the Soyuz-5 spacecraft complex was appointed Director General of the enterprise Dmitry Baranov, the chief designer of the Soyuz-5 missile, Alexander Cherevan.
As part of the Soyuz-5 missile, unique liquid rocket engines will be used: at the first stage – the engine RD-171MV of the development of the Surgean and Production Association “Energomash” named after Academician V.P. Glushko (enters Roscosmos), at the second stage – RD-0124MS developing the design bureau of Himavtomatics (enters Roscosmos). RD-171MV is the most powerful liquid rocket engine in the world (traction – 740 tons), RD-0124MS has a record specific impulse (361 s).
As part of a new rocket carrier will be used by the control system created on the domestic element base. It is responsible for its development a subsidiary of the RCC “Progress” – a scientific and production association of automatics named after Academician N.A. Semikhatova (Yekaterinburg, enters Roscosmos). The application of a new management system will simplify the process of preparing the “Soyuz-5” missile for a start-up on the cosmodrome and minimizes the composition of ground-based equipment on the starting complex.
