The engine is intended for LV upper stages. It consists of combustion chamber and pneumatic pump (PP) of propellants supply.

- The engine provides multiple restarts;
- Fixed value of the thrust within a range of 200...600 kgf is provided by adjustment of only PP (without additional tests);
- Consumption of the working gas is lesser by 1,4...1,7 times in comparison with traditional expulsion system of propellant supply;
- High accuracy of the mixture ratio maintenance;
- The tank systems operarte under low pressurization;
- Application of PP allows thrust increase of existing engines with propellant expulsion system by 1,4...1,8 times without changing the gas stock;
- The mass-dimensional and performance cxharacteristics are upgraded (especially owing to propellant stock uncreasing).

The engine is provided with a principally novel system of propellant supply under use of the pneumatic pump.
Configuration of the engine contains design elements and technical solutions of serially produced engines such as combustion chamber, PP elements, control units etc.
