INITIATING DEVICE FOR ROCKET STAGE SEPARATION MECHANISM Russian patent published in 2024 - IPC B64G1/64 

FIELD: rocket technology.

SUBSTANCE: invention relates to rocket stage separation systems, and more specifically to initiating devices. The initiating device of the rocket stage separation mechanism contains a housing communicating with the engine combustion chamber, a charge with an igniter primer, a main piston and a firing pin. The housing consists of three parts. A split ring is installed in the front part of the housing, covered by a locking piston, pressed by a retaining spring with emphasis on the middle part of the body. The main piston is installed in the middle part of the housing, covering the body of the striker. In this case, the main piston is pressed into the limiter by the main spring with a compression force greater than the compression force of the retaining spring. The limiter is installed in the rear part of the housing, which is equipped with a receiving hole in communication with the engine combustion chamber. The combat piston is equipped with a final position lock, which is included in the main piston and covers the axis of the striker.

EFFECT: preservation of mechanical characteristics during long-term operation at elevated temperatures.
