DETACHABLE ROCKET-PROPELLED MISSILE Russian patent published in 2014 - IPC F42B12/58 F42B15/36 

FIELD: weapons and ammunition.

SUBSTANCE: dividing rocket-propelled missile comprises a rocket engine with the bottom, a detachable head part, a parachute compartment, and also a detonation device. The head part comprises a housing with a bottom, an explosive and destructive elements. The parachute compartment contains the charge of detachment, the piston and the unit of forcing. The detonation device comprises the conical and cylindrical parts of the housing, in which an electronic time device with the safety and arming unit are located, a reaction target sensor with an impact mechanism and an actuation unit, equipped with powder charges. The head part is provided with a central gas-duct, gas-dynamically binding the volume of the accumulation cup of the housing with a behind piston working volume. In the bottom of the head part the axial channels are made, linking the behind piston working volume with the behind bottom compensatory area of the rocket engine. The actuation unit is fixed at the rear part of the cylindrical pipe of the detonator housing. Simultaneously, the actuation unit is provided with a valve mechanism mounted in the central channel of the cup at the side of the ejection charge of the safety and arming unit. At the junction area of the conical and cylindrical surfaces of the housing of the detonator the thick-walled metal jumper with a central channel covered with plug and the groove is mounted.

EFFECT: improving reliability of issuing igniter pulse and detaching of the head part from the missile.
