CONTAINERISED ROCKET Russian patent published in 2008 - IPC F42B15/00 

FIELD: weapons.

SUBSTANCE: invention is intended for the use in rockets that are launched from a container. A rocket comprises a rocket engine and a mechanism for retaining the rocket in its container having the form of a spring ring and a gate. The gate is formed as a stepped bushing that fastens the split spring ring in the initial position by enveloping its outer diameter to the engine housing. A thrust bushing and a push bushing are mounted on the outer surface of the stepped bushing and their ends have projections. The projections of the thrust bushing thrust against the engine, and ones of the push bushing rest against the outer diameter of the engine taper surface and their bevelled recess is compatible with bevels formed on the inner surface of the split spring ring. The stepped and push bushing move longitudinally with respect to one another and the split spring ring. A longitudinal clearance between the push bushing end facing the engine and the stepped bushing is not less than the longitudinal envelopment of the spring split ring by the stepped bushing. Longitudinal clearances between another end of the push bushing and oppositely disposed ends of the other parts are not less than the length of the bevelled recess on the outer surface of the push bushing projections. The retaining mechanism is attached by means of a threaded ring to the container that presses the thrust bushing against the engine end. This type of securing the rocket in its container ensures reliable fixation of the rocket during its transportation and storage, and during its launching - at the moment of opening of the split spring ring - minimal perturbations in flight.

EFFECT: ensuring reliable fixation of the rocket during its transportation and storage, and minimal perturbations in flight during its launching.
