MOSCOW, December 27 The Scientific Research Institute of Mechanical Engineering (NIIMash) in the Sverdlovsk region is preparing in the near future to test a firing model of the engine, with the help of which cosmonauts will to control a promising manned spacecraft, the Roscosmos press service told reporters.
“At the Research Institute of Mechanical Engineering… a new hydrogen peroxide rocket engine is being tested for a promising manned spacecraft. Development tests are currently being carried out and at the same time engines are being manufactured to complete the firing mock-up of the descent actuator system and other mock-ups. Testing of the firing mock-up is planned to be carried out at NIIMash in the near future time,” the message says.
It is noted that the company has been working on engines in which the working fluid is 85 percent hydrogen peroxide since 2020. When working with such fuel, special precautions, requirements for cleanliness, technological devices and tools are required.
The new peroxide engine was developed by the Korolev Rocket and Space Corporation (RSC) Energia (part of Roscosmos). The electrohydraulic valve, which is part of the engine, was developed at NIIMash. The engine is intended for use in the return vehicle of a “promising manned spacecraft.”
Roscosmos emphasized that the Ural enterprise (located in Nizhnyaya Salda, Sverdlovsk region) manufactures parts and assembly units, and also assembles and tests the peroxide rocket engines themselves. In particular, the first engines successfully passed design tests in May 2023.
It is not said what kind of promising ship we are talking about. However, it is known that since 2009, Russia has been developing the Advanced Transport Ship (PTK), also known under the names “Federation” and “Eagle”. Initially, its first flight was planned for 2015, now expected in 2028-2029.
