FIELD: rocket and space technology.
SUBSTANCE: invention relates to the field of rocket and space technology, and more specifically to the first stage of the launch vehicle. The reusable first stage of the launch vehicle (LV) contains a nose section with a fairing, a fuel section and a tail section containing a combined power plant (CPP). The CPP consists of a ramjet engine and a liquid propellant rocket engine (LPRE). The ramjet engine has a shortened central body of the pin nozzle. The inner cavity of the annular combustion chamber contains a fuel manifold, a flame stabilizer and a heat exchanger. The rocket engine is located in the inner cavity of the shortened central body of the pin nozzle. A bearing aerodynamic surface is attached to the outer body of the ramjet, which is a fixed swept wing, on the tips and cantilever parts of which control aerodynamic surfaces are located.
EFFECT: improved mass-dimensional characteristics.
