SOLID-PROPELLANT ACCELERATION ENGINE PLANT Russian patent published in 2003 - IPC

FIELD: aircraft industry. SUBSTANCE: proposed solid-propellant acceleration engine plant of flying vehicle is furnished with tail obturator compartment with gas vanes rigidly coupled with cranks. Rear edge of tail obturator compartment is arranged after nozzle exit section of acceleration engine plant and detachable aerodynamic section is installed on engine plant and provided with sockets for fastening air vanes. Slots are made on cranks of gas vanes to provide engagement with air vanes. Detachable aerodynamic is furnished with hermetic bottom. Sealing units are installed on axles of gas vanes and on rear edge of tail obturator compartment. Locking of detachable aerodynamic section on tail obturator compartment in axial direction is provided by members with calibrated weakened section to break under action of interchamber pressure of acceleration engine plant, and in transverse direction, by pins located close to members with calibrated weakened section. Invention simplifies design, improved reliability and reduces mass of flying vehicle. EFFECT: enlarged functional capabilities of acceleration engine plant. 3 cl, 6 dwg
