THRUST CUT-OFF ASSEMBLY OF SOLID-PROPELLANT ROCKET ENGINE Russian patent published in 2018 - IPC F02K9/92

Abstract RU 2664638 C2

FIELD: rocket technics.

SUBSTANCE: invention relates to rocket technology and can be used in the creation of a jet engine cut-off assembly for solid propellant. Thrust cut-off assembly includes the plug (blind plug), which hermetically closes the engine cavity, the pusher, which is mounted with the possibility of axial movement and is equipped with the stroke limiter. Plug (blind plug) and the usher are spaced and hold the shell. Pusher rests against the ring, which is rigidly fastened to the shell, and for the displacement and centering of the ring, the guides located between the sustainer stage of the rocket and the rocket engine are installed.

EFFECT: invention allows to increase the reliability of the operation of the thrust cut-off assembly and to simplify its design.
