FIELD: transport.
SUBSTANCE: proposed invention relates to rocketry, particularly to ejector device for small rockets or any other payload. Proposed device comprises cylinder-piston system, pyrocartridge, solid-propellant gas generator and central tube jointed with pyrocartridge. Note here that said tube is hollow, while has generator charge consists of multi-grains arranged between central tube and gas generator casing. Rear bottom profile is made conical while central tube is arranged with clearance with respect to front bottom. Gas generator casing is communicated via gas duct with sub piston chamber of cylinder-piston system. Said pyrocartridge has charges of brown powder, each making 0.07 to 0.11 of the weight of solid-propellant charge.
EFFECT: reduced weight and overall dimensions, higher efficiency.
