DIRECT-FLOW ROCKET PROJECTILE Russian patent published in 2018 - IPC F42B10/00 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to the ammunition production and use, and can be used in any firearms (infantry, artillery), in the electromagnetic accelerators, as well as for the underwater use. This technical result is achieved by the fact that in a device comprising a housing that externally has a barrel-shaped (oval) shape, inside it has a profiled through hole with two critical sections 1 and 3, between which there is section 2 with the largest expansion. Solid fuel 7 is placed along the walls of the hole, propellant charge 8 and combustible wad 9 after input critical section 1 are placed inside the cavity. Input critical cross section 1 is smaller than output critical cross section 3. Combination of sections 4, 1, 2, 3, 5 forms two opposite Loval nozzles.

EFFECT: technical task of the proposed direct-flow rocket projectile is to increase the range and stability of the projectile’s flight by reducing its aerodynamic resistance and increasing its reactive power, simplifying its design and manufacturing technology.
