ALTITUDE ROCKET ASSISTED PROJECTILE AND METHOD OF ITS FUNCTIONING Russian patent published in 2018 - IPC F42B12/00 

FIELD: weapon and ammunition.

SUBSTANCE: device contains apoint fuse, a screw head, a warhead body tube, an explosive, a steadying band and a ducted rocket propulsion system. This propulsion system is located in the stern of the projectile and contains a gas generator with a solid fuel charge, a support grid and an adjacent ballistic fuel pellet, an afterburner, and an annular air intake. The afterburner is cylindrical, located behind the support grid of the gas generator and has slotted nozzles. Striking elements are placed in the body of the combat unit, along with the explosive. The afterburner allows high-temperature afterburning of the combustion products of the gas generator's fuel in pulsating mode with a frequency in the range from 200 to 3000 Hz. At the exit of the afterburner, the rate of flow of combustion products is about 2000 m/s. With the help of slotted nozzles, it is possible to form flat jets to stabilise the control of a rocket assisted projectile. As part of the group of inventions, a method of functioning of a high-altitude active-rocket projectile is envisaged. When the rocket assisted projectile moves along the barrel channel, a ducted rocket propulsion system is launched. Lead high-altituderocket assisted projectile in the calculated point of a probable meeting with a fast-flying target. Undermine the combat part of the high-altitude rocket assisted projectile, ensure the spread of the damaging elements. Create a veil of them. Ensure the interaction of the attacking elements with a fast-flying target and its destruction.

EFFECT: increase in the height and probability of hitting a fast-flying target with anti-aircraft and anti-ballistic missile defenses by improving the completeness of fuel combustion, fuel efficiency and mass-dimensional characteristics of a high-altitude rocket assisted projectile.
