SUPERSONIC ROCKET MISSILE Russian patent published in 2009 - IPC F42B15/00 

FIELD: weapons.

SUBSTANCE: invention concerns military technics, namely to supersonic rocket missiles and can be used at creation of systems of a volley fire. The supersonic rocket missile contains the case with aligning thickenings and the engine with the nozzle block closed by an aerodynamic fair. Unlike a prototype in an aerodynamic fair before critical section of a nozzle a number of entrance apertures on distance of (0.35...0.4) l_k from it, and behind critical section of a nozzle on distance of (0.55...0.6) l_k from a tail end face of a shell - a number of exhaust outlets of the same area is carried out. Simultaneously on the shell case before entrance apertures on distance of (0.22...0.33) l_k the ledge which diameter does not exceed diameter of aligning thickenings, l_k - distance between a plane of critical section of a nozzle and a tail end face of a shell, m. is carried out.

EFFECT: decrease of thermal load on the nozzle block at the expense of its compulsory cooling by a running air stream in 1.5...2 times and increase at the expense of it range of fire and stability of traction characteristics of the engine.
