SELF-GUIDED ELECTRIC ROCKET Russian patent published in 2019 - IPC F42B15/01 

FIELD: astronautics.

SUBSTANCE: invention relates to rockets which use electric power of an onboard electric power source to create an air jet thrust and flight. Electric missile propulsion system comprises a hollow body with a self-guidance head mounted on its head. In the tail part there is an electric jet propulsor - EJP. It comprises multi-bladed impeller. Control computer module, stroke regulator and valve electric motor are installed inside EJP housing. Multi-bladed impeller is fixed on said electric motor shaft. At that, the EJP is configured to measure the angular mismatch of its axis with a predetermined direction of its motion in flight by means of a set of vanes installed on the head part of the EJP hull. Digital transducers of its angles are connected via digital interface with self-guidance head and control computing module. This module is designed to process measured mismatches, to output correcting signal to control rudders, to zero value of mismatch and to maintain axis of EJP with direction of its movement. EJP control rudders are installed in jet airflow created by EJP impeller and connected via steering drives with control electric module of computer system.

EFFECT: technical result is higher manoeuvrability of missile, accuracy of targeting and reliability of operation.
