摘要
FIELD: rocket engineering. SUBSTANCE: solid-propellant rocket engine guided projectile has a case with nozzles, ignitor, powder cartridge with after-burning section and central passage, and is provided with exhaust gas cleaner made in the form of blind sectional cavities formed with pyramidal truncated projections. Small bases of the projections are placed in parallel to outer surface of the afterburning section. Large bases are placed just opposite the nozzles. A tube is placed inside the passage of the powder cartridge. The tube is coated with a material with low heat transfer coefficient. Thermal- resistant plastic may be used as the material. As this takes place tube O. D. is 0.8 - 0.9 central passage diameter. Solid propellant ignitor of the rocket engine has the after- burning chamber with outlets placed on the side of engine bottom. The outlets are filled with ignition powder pellets and initiating composition linked to the central passage of the powder cartridge through radial passages. EFFECT: low smoking up. 2 cl, 3 dwg
