FIELD: engines and pumps. ^ SUBSTANCE: invention relates to rocket engine production and can be used in producing generatorless fluid propellant rocket engine running on cryogenic components, for example oxygen and hydrogen. Fluid propellant rocket engine comprises circular chamber with mixing head and plate-tape outer-expansion nozzle, shaped central body and circular critical section. Control assemblies and feed assemblies comprising turbo pump unit with turbine are arranged inside said shaped central body. Said shaped central body consists of several parts. At least one part can revolve in radial axially symmetric direction about lengthwise axis of shaped central body and is articulated with feed assemblies. Note that central body outer surface accommodates blades to rotate it. ^ EFFECT: higher specific thrust pulse, simplified pneumohydraulic circuit, higher combustion chamber pressure at minimum overall dimensions. ^ 1 dwg |
