BULLET CONTROL METHOD AND CONTROLLED BULLET Russian patent published in 2020 - IPC F42B15/01 

FIELD: astronautics.

SUBSTANCE: invention relates to the field of rocket equipment and can be used in small-size rocket systems, and including bullets. According to the method, the controlled bullet is accelerated by the starting engine. Then the starter motor is separated and the cruise stage is directed to the target in the optical beam using an inertial navigation system with bullet banking angle sensors to extract the coordinate in the roll channel. When the controlled bullet comes out of the tubular guide, two or more stabilizers with decentering photodetectors are installed, which are equipped with a controlled bullet. Further, the space is scanned along the line of sight with an optical beam in the form of knife-like laser radiation beams. This radiation is received by photoreceiving devices and is transferred at first into coordinates of each of photodetectors, and then - into angle of roll as per analytical dependence taking into account current coordinates of photodetectors and distance between them. At that, before separation of starting engine during flight, roll angle sensor is calibrated as per analytical dependencies. After separation of the starting engine, controlled flight is performed using a calibrated roll angle sensor.

EFFECT: technical result is increased accuracy of firing.
