FIELD: rocket manufacturing.
SUBSTANCE: rocket solid-propellant power plant incorporates the previous and subsequent stage engines with combustion chambers separated by a common bottom and a subsequent stage engine hinged nozzle moved into the combustion chamber and provided with a steering gear. The previous stage combustion chamber accommodates, right behind the hinged nozzle and with a gap, a stationary mouth. The latter is coupled to the common bottom by a shell to form a closed space between the said shell and the hinged nozzle walls to accommodate a steering gear. The said stationary mouth is designed so that with hinged nozzle departed by a maximum angle the said nozzle outlet section does not beyond the stationary mouth inlet section.
EFFECT: higher reliability of the power plant ensured by the steering gear thermal protection.
