Orbital propulsion system is developed for Ukraine-Russian Dnepr LV.

The engine is intended for creation thrust and flight control in all stabilizing channels of launch vehicle upper stages. Pneumatic system of components supplying is implemented in the construction. It is totally new system of propellant supply due to using pneumatic unit, which provides high energy and mass characteristics.
