MOLNIYA-M Launch Vehicle

Companies & Organizations:

The Molniya-M launch vehicle is intended to place space objects to the Moon, to the planets of the Solar System, as well as to inject Molniya- and Prognoz-type spacecraft into high-elliptical near- Earth orbit. At present pre-launch preparation and launching of the Molniya-M LV can be realized at the Plesetsk Cosmodrome by using technical and launch complexes currently in operation for Souyz-U LVs.

 

The Molniya-M is designed as a system with parallel separation of the lateral rocket engine assemblies upon the first stage burnout and transverse separation of the second stage engine assembly after burnout. Each of the LV assemblies has its own propulsion unit using non-toxic propellants (oxygen and kerosene).

 

Assembly ‘I’, like that in Souyz-U LV, is used as the third stage. Assembly ‘L’ (the upper stage) is fitted up with a cryogenic liquid propellant engine that is ignited in zero gravity after an hour-long earth referenced (intermediate) orbit flight. Compressed gas is used to enable coasting flight control of the upper stage with the nozzle units actuating the required maneuvering. Assembly ‘L’ includes an autonomous inertial control system.
