BICALIBER ROCKET Russian patent published in 2018 - IPC F42B15/00

Abstract RU 2657300 C1

FIELD: rocket engineering.

SUBSTANCE: invention relates to rocketry and can be used in small missiles. Bicaliber rocket comprises a detachable booster engine with a landing socket, into which a sustainer stern with an annular nozzle located in front of the engine end, is installed. Engine and annular nozzle are connected by annular sectors with protrusions located in trapezoidal grooves of the engine and annular nozzle respectively. Grooves in cross section are made in the form of versatile trapezoids. Annular cavities are formed between the ends of the annular sectors and the reciprocating surfaces of the grooves. Each annular sector is provided with a push in the form of a rod with a spring mounted to interact radially with the outer surface of the protrusion of the annular sector located in the groove of the nozzle. Spring of the pusher is plate-shaped and cantilevered in the front part of the annular nozzle.

EFFECT: invention provides increased reliability of work by protection of annular sectors in the grooves from seizing.
