ROCKET Russian patent published in 2018 - IPC F42B15/00 F42B15/36 F02K9/76 

FIELD: rocket equipment.

SUBSTANCE: invention relates to the field of rocket equipment and can be used in rockets with a detachable launching stage. Rocket contains a march stage and a detachable launching stage with an engine and separation mechanism. Separation of the starting stage after the end of the engine operation from the march stage occurs through the separation mechanism established between the march and the starting stages. Separation mechanism includes a frame and a nozzle fixed in the frame with a gas generator placed inside, while the frame is fixed with a union nut on the engine, and the nozzle is fastened through hooks with the march stage, the nozzle is made stepped, with an outer diameter smaller than the internal diameter of the frame, while annular front and rear sections contacting the frame are designed on the outer surface of the nozzle. In the cylindrical surface of the frame, the adjusting and catching screws are radially positioned and grooves are provided, with the adjusting screws in the frame fixing the nozzles and being located in front of the front ring section, and the catching screws being located behind the front annular section of the nozzle. On the threaded end of the catching screws, a conical surface is formed, projecting into the gap between the frame and the nozzle. Grooves are located between the catching screws and the annular ring section of the nozzle, the distance from the axis of the grooves to the axis of the catching screws being greater than the thickness of the rear annular section of the nozzle, and a chamfer is provided on the front annular section of the nozzle.

EFFECT: technical result of the proposed solution is to increase the reliability of the rocket separation system.
