TORPEDO SOLID-PROPELLANT CONTROLLED POWER PLANT Russian patent published in 2007 - IPC F42B19/18 

FIELD: torpedo armament, in particularly, torpedo power plants.

SUBSTANCE: the torpedo solid-propellant controlled power plant consists of a body, end-burning solid-propellant charge with a sealed piston at the armored end, combustion chamber with a fixed cooled heated strip and an injector unit, turbine engine with a double-section nozzle assembly, whose one section is coupled to the combustion chamber of the high-pressure outboard water plunger pump through a double-position gas electric valve, the plunger pump has an electromechanism for changing the pump capacity and two groups of plungers of a different working volume with their pressure exhaust manifolds, one of which is coupled to the beyond-the piston space through a line, and the other is connected to the line for cooling the heated strip and its injector unit for cooling the combustion products of the solid-propellant charge, engine revolution transducer control electronic unit.

EFFECT: enhanced reliability of the torpedo power plant section.
