BICALIBER MISSILE (VERSION) Russian patent published in 2017 - IPC F42B15/00 F42B15/36 

FIELD: weapons and ammunition.

SUBSTANCE: bicaliber missile (version 1) contains a booster engine and a transitional fair connected mechanically thereto, which are mounted telescopically on the stern of the main missile. The main missile and the engine are connected with each other with a discontinuous screw which breaking force is less than the breaking force of the mechanical connection between the engine and the transitional fair but exceeds the force from overload on the main missile in operation, and is less than the difference of aeroballistic forces on the booster engine and the sub-caliber main missile during flight at the end of boost. Bicaliber missile (version 2) contains a booster engine connected telescopically to the sub-caliber main missile. The main missile and the booster engine are connected with each other with a interstage joint made in the form of a rod fixed at the end of the main missile and set into a sleeve fixed to the bottom part of the telescopic connection of the engine. The rod and the sleeve are fixed to each other with a pin which cutting force exceeds the force on the main missile during operation, and is less than the force on the main missile during boost; there are gaps between the ends of the main missile and engine; the size of the gaps should fit the lead required to shear the pin.

EFFECT: invention improves reliability of the perturbations damping of the main missile during separation and simplifies the missile design.
