SMALL SPACECRAFT JET CONTROL SYSTEM Russian patent published in 2024 - IPC F02K9/26 B64G1/26 

FIELD: cosmonautics.

SUBSTANCE: invention relates to space engineering, in particular, to spacecraft orientation and flight jet control means. Jet control system of small spacecraft includes correcting rocket orientation and flight stabilization engines, made as a single unit, located outside the spacecraft body and connected to the flight control unit, at that, the unit is equipped with solid-propellant jet micromotors, made with an optical insert from a solid transparent heat-resistant material on the end, and comprises at least one laser igniter of solid-fuel charge pyrotechnic igniter in jet micromotor, installed before optical insert of jet micromotor. Unit of solid-propellant jet micromotors is made in the form of an annular cage with possibility of cyclic rotation at least through an angle equal to the angle between adjacent jet micromotors relative to the body of the small spacecraft. Dimensions of the housing of the solid-propellant jet micromotor correspond to the dimensions of the small-calibre cartridge case. Solid-propellant charge of the jet micromotor is made up of a set of parallel channel blocks. Optical insert is made of quartz glass. Solid-propellant jet micromotors protrude beyond the annular holder by at least the length of the supersonic jet nozzle. Nozzle of the supersonic jet stream is made with possibility of deviation through an angle from the central axis of the solid-propellant jet micromotor.

EFFECT: invention ensures reduction of dimensions and weight reduction of solid-propellant rocket engines, allowing their use on small spacecrafts.
