On the stand of No. 1 enterprise "UMZ them. Makarova" has successfully completed the second stage of the final flight tests, single-chamber liquid rocket engine РД861К developed by SE "CB "southern" and manufactured by enterprise "UMZ them. Makarov".

the tests (three series of five inclusions with a total duration 1601,6 seconds) finished a full cycle of ground tests of the engine and finally confirmed the operability of selected structures, systems and components of the engine within the range of specified operating conditions, matching the basic characteristics РД861К specified in Technical specifications. It was the final and most important ground tests, which confirmed the readiness of the engine for flight tests in the composition stage of LV.

Recall that РД861К is the engine of the upper stage of the launch notices, with a turbopump feed system components fuel, without afterburning gas and its injection in a supercritical part of the nozzle. The engine is able to provide reusable launch and thrust vector control through the channels of pitch and yaw in space during insertion of the payload into the target point of the trajectory.

Liquid rocket engine РД861К is part of the third stage rocket "Cyclone-4", intended for propulsion and maneuvering. The engine you plan to use as the main engine of the second stage of the new carrier rocket "Cyclone-4M".
