CONTROLLED BULLET Russian patent published in 2020 - IPC F42B10/12 F42B15/01 

FIELD: astronautics.

SUBSTANCE: invention relates to rocket engineering and can be used in small-size rocket systems. Controlled bullet is made as per two-stage coned-bore scheme and comprises detachable start-up engine of conical shape. It has tandem rear position and larger gauge relative to sustainer stage. Sustainer stage includes a warhead and a control unit. Stern of the control unit is located in the central tube of the detachable starter motor. There is a transient fairing with a gas-dynamic control device installed in it. Nozzles of gas-dynamic device are brought out of transient fairing in radial direction. Besides, gas-dynamic control device is equipped with accumulating chamber. It is connected to the jet made in the front bottom of the separated starting engine. Accumulating chamber is configured to receive working medium from combustion chamber of detachable starting engine, is arranged around sustainer stage and provides stabilization of pressure of combustion products of solid fuel of detachable starting engine for their supply to nozzles of radial direction of gas-dynamic device. This device provides the possibility to control its nozzles thrust till the start engine separation and is made with possibility to ensure the bullet rotation relative to the longitudinal axis.

EFFECT: technical result is reduction of dimensions and weight of controlled bullet with increase in its reliability.
