SOLID-PROPELLANT ROCKET ENGINE

摘要

FIELD: operation of engine with charges from high-pulse solid fuels; jet projectiles with wholesale destruction zone". SUBSTANCE: rocket engine has housing where sectional solid-propellant charge, igniter and nozzle are mounted; nozzle includes supersonic bell mouth, insert and inlet cone. Igniter is made in form of microengine with perforated housing which is secured on front bottom of housing and is located in star-shaped passage of front section of change at spaced relation. Sectional solid-propellant charge is made at relationship of maximum diameter of star-shaped passage of front section of change to maximum diameter of narrowing section of passage of rear section of change protected by invention. EFFECT: increased power characteristics of engine due to optimal relationship of geometric sizes of individual units and parts. 2 dwg
