METHOD FOR THROWING OF AXISYMMETRIC OGIVE PROJECTILE FROM RIFLED BARREL OF ARM WITH PRESSURE OF POWDER GASES IN UNDERWATER AND AIR MEDIUM AND DEVICE FOR ITS REALISATION Russian patent published in 2009 - IPC F42B10/40 F42B30/00 F41A1/00 

FIELD: weapons and ammunition.

SUBSTANCE: in method from nose part of axisymmetric ogive projectile a rotary jet of missile powder combustion gases is emitted, which creates double-phase medium with water or air in trajectory of projectile movement. For this purpose in hollow ogive shell of projectile in its nose part there is an axial hole with blades arranged inside at its outlet. Outside hollow shell, a calibrated nozzle is inserted into this hole, being coated with membrane and separated from remaining volume of hollow shell with a transition space that adjoins inlet of nozzle and is limited with diaphragm that fixes charges of missile powder. Blasting cap is closed with stern by ring of conductor with hole for sting of striker connected to round metal plate, which rests against cylindrical protrusion of stern along edge of its diametre and is sealed along its end with a thin plate that contacts with it.

EFFECT: increased distance and stability of projectile flight.
