SOLID-PROPELLANT ROCKET ENGINE Russian patent published in 1999 - IPC

Abstract RU 2133864 C1

FIELD: rocket engineering. SUBSTANCE: given rocket engine is intended to impart missile with forward motion and to deliver head part to target. Engine has body including telescopic tube, charge of solid propellant of unrestricted burning, igniting device, electric igniter, prenozzle diaphragm and nozzle unit. Engine is fitted with holder mounted near front butt of charge and is made in the form of ring with strips anchored in ring. Strips are positioned in pairs in symmetry to each other and in clearance between tube of body and outer charge grain. Length of cantilever and thickness of burning outline of internal grain make up quantities protected by invention. Igniting device is located in recess of ribs on side of butt of charge. Central part of grain has two elliptical holes symmetric relative to longitudinal tube which major axes are arranged in diametrical plane. Summary area of holes limited by contour of conduit of internal grain makes up quantity protected by invention. Usage of optimal relations of geometric sizes of individual units and elements provides for reliable operation of engine in all ranges of working temperatures with maximum value of total pulse and minimal value over its spread and decreases its passive mass. EFFECT: increased functional reliability of engine. 5 dwg
