SOLID FUEL GAS GENERATOR Russian patent published in 2017 - IPC F23R5/00 F02K9/32 

FIELD: machine engineering.

SUBSTANCE: gas generator comprises a central hollow cylinder closed at one end and open in the form of a converging nozzle from the other end, local gas-generating parts of solid fuel charge located in the cylinder with separating partitions therebetween, and an ignition system of the charge parts. The gas generator further comprises a cylindrical body with peripheral and central filler charges, a resonance chamber and two circular grids. The cylindrical body is provided with a bottom on one side and a conical adapter with a branch pipe on the other side. The resonance chamber is made in the form of a cup with a piston located therein and installed in the center of the body bottom. The filler charges are installed in the body between inlet and outlet circular grids with formation of a circular channel therebetween and coaxial the hollow cylinder. The hollow cylinder is in axial hole of the central filler charge and faces the nozzle along the axis towards the resonance chamber with formation of an intermediate cavity therebetween communicating through the circular channel between the filler charges with the branch pipe.

EFFECT: possibility for repeated activation of the gas generator and controlling the mass flow rate of gaseous low-temperature working medium, increased reliability of the gas generator.
