MISSILE WITH AIR-JET ENGINE Russian patent published in 2019 - IPC F42B15/00 

FIELD: astronautics.

SUBSTANCE: invention relates to the field of rocket equipment, namely to rockets with an air-jet engine - AJE. Device comprises front air intake device. It includes central body with cone of external-internal compression, shell ring with undercut, fixed on central body by means of pylons uniformly located in circumferential direction, combustion chamber with injectors of fuel supply, annular supersonic nozzle at combustion chamber outlet, gas generator, warhead, starting engine of solid fuel, stabilizer. According to invention, AJE is equipped with cone position adjustment system. It is located in central body and is made in form of hydraulic cylinder with piston. Hydraulic cylinder sub-piston cavity is connected with injectors of fuel supply into combustion chamber at gas generator start-up. Hydraulic cylinder above-piston cavity is connected with differential throttle, providing cone movement along axis by specified value relative to central body and shell. Pylons are fixed on the central body at an angle of attack to the longitudinal axis of the missile and are turned towards its rotation. Annular nozzle is located on the shell and is made in the form of an expanding fan extending beyond the rocket launcher during its flight.

EFFECT: technical result is increase in speed and range of missile flight, expansion of traction-aerodynamic characteristics of AJE.
