FIELD: rocketry. SUBSTANCE: proposed solid-propellant rocket engine contains housing, solid propellant charge, nozzle unit, igniter, sealing-and-starting unit and cartridge. Sealing-and-starting unit has member made in form of several telescopic ring bushi9ngs interconnected by spline joint and installed for axial displacement relative to each other direction of powder gases flow. Cartridge is arranged in central ring bushing connected by reheat tube with fitted-on support resting on subsonic part of nozzle. EFFECT: reduced spread of reheat pressure and dispersion of rocket trajectory, improved manufacturability of rocket engine and reliability of rocket as a whole. 2 dwg |
