SOLID-PROPELLANT GAS GENERATOR FOR UNDERWATER USE

摘要

FIELD: rocket science.;SUBSTANCE: invention relates to rocket engineering, and more particularly to regulation of solid-fuel gas generating systems for underwater applications. Solid-fuel gas generator for underwater use comprises mounted on a support a cylindrical stick of solid propellant, at upper end of which is there is a localiser of combustion zone in form of an inverted heat-resistant cup with electric heater, and a control means. Localiser of combustion zone is formed as a releasable hinge pair with horizontal hinge axis on lateral surface with possibility of rotation of electric heater relative to heat-resistant glass in which there is a perforated bottom. On opposite side from hinge axis electric heater is attached to bracket on which actuator control means configured in form of an electric motor with a propeller blade.;EFFECT: invention enables to adjust rate of gas production, including interruption of combustion and re-ignition, without limiting length of valve checkers.;3 cl, 4 dwg
