METHOD OF STARTING BOOSTER OF CONTROLLED REACTOR CHARGE AND INERTIAL CIRCUIT BODY Russian patent published in 2017 - IPC F02K9/95 F42B15/10 

FIELD: weapon and ammunition.

SUBSTANCE: when launching a booster of a guided missile, the closure of the electrical circuit of the electric igniter of the engine is produced by two inertia contactors under the action of the starting acceleration. The circuit closing time and the acceleration value at which the circuit closes the second inertial contactor is less than the corresponding values of the first inertial contactor. To realise this method, an inertial closing device is used, which ensures the closure of the electrical circuit of the electric ignitor of the propulsion engine under the action of the starting acceleration, containing two inertial contactors. The inertial contactors are located in the same housing with two parallel channels in which there are two movable inertial load-contacts, each of which interacts with the spring and is able to interact with its pair of fixed contacts when moving under the action of the starting acceleration by the stroke in time t1 and t2 respectively. Weights of cargo-contacts and spring rigidity are selected in such a way that the ratio t2/t1>1.2 is satisfied.

EFFECT: group of inventions makes it possible to increase the safety of the projectile during its operation and combat use by eliminating the closure of the electrical circuit of the electric ignitor at accelerations that occur when the product falls.
