PULSE GAS GENERATOR Russian patent published in 2023 - IPC F02K9/08 B01J7/00 

FIELD: rocket technology.

SUBSTANCE: invention can be used in squibs in the design, experimental development, manufacture and operation of ejection devices for ejecting small and medium weight loads from their carriers. The pulse gas generator includes channel pyrotechnic solid propellant charge sticks initiated by an igniter coaxial to a cylindrical body, at the distal end of which a grate is mounted, whereas the channel pyrotechnic solid propellant charge sticks having corrugations at the ends are installed and fixed in the cylindrical body sequentially in longitudinal abutment to each other with a guaranteed annular gap relative to the cylindrical body between the threaded sleeve carrying the electric igniter equipped with bottom fire-transfer communication openings, and the overlapped membrane installed in the grate outlet nozzle on the support element placed inside the coaxial diffuser and configured for longitudinal relative movements, moreover, the grate coaxial with the cylindrical body has a radial dispersed outlet openings partially blocked by a coaxial diffuser rigidly connected to the cylindrical body. Each of the used channel pyrotechnic solid propellant charge sticks is made with an axial channel and mounted in a cylindrical body with a guaranteed annular gap formed by fixing the sticks between at least three equidistant longitudinal spacers fixed on the inner surface of the cylindrical body along its length, made of elastic material.

EFFECT: invention provides expansion of functionality, increase of speed and reliability.
