Low thrust engine 17D16
A unique museum exhibit is the original low-thrust engine 17D16 from the integrated propulsion system 17D11 of the Buran spacecraft.
The original low-thrust engine 17D16 was part of the integrated propulsion system 17D11 of the Buran reusable orbital vehicle. This engine was used to maneuver and orient the spacecraft in space, providing the necessary precision in flight control.
Main characteristics of the 17D16 engine:
- Type: Liquid jet engine (LPRE).
- Fuel components:
- Combustible component: unsymmetrical dimethylhydrazine (UDMH).
- Oxidizing agent: dinitrogen tetroxide (AT).
- Operating modes: Can function both continuously and pulsed.
- Traction: Small values (~100 N).
- Adjustability: Provided thrust control and thrust vector direction.
Features of design and operation:
- The engine could be turned on and off repeatedly, maintaining a given flight path and the position of the ship relative to the Earth.
- The use of a multiple start system made it possible to significantly increase the service life of the engines.
- High reliability and ability to operate stably in microgravity conditions.
Role in mission "Buran":
These engines ensured the safety and efficiency of the flight, allowing the necessary maneuvers in orbit, including trajectory correction, docking with space objects and landing. Thanks to these characteristics, the Buran ship received a unique controlled descent and landing system.
Despite successful testing and the launch of the Buran program, the program was terminated. However, the advances and technologies developed for the project continue to be used and improved in modern space programs.
