MINIATURE SOLID PROPELLANT ENGINE Russian patent published in 2012 - IPC F02K9/95

Abstract RU 2443896 C2

FIELD: engines and pumps.

SUBSTANCE: proposed engine comprises casing with charge. Igniter with pyro composition enclosed in thin-wall tight envelopment is arranged on grid located nearby charge end face. Pyrocartridge with afterburner tube is arranged in casing cover. Afterburner tube edge is spaced apart from igniter envelopment. Igniter envelopment has cylindrical recess made on the side of afterburner tube and aligned with the latter that feature the following relations of recess height h and diameter D of recess from afterburner tube inner diameter d: d≤h≤2d and 3d≤D≤5d.

EFFECT: higher reliability and efficiency.
