JET PROJECTILE Russian patent published in 2017 - IPC F42B10/14 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to the weapon field, namely, to the unguided missiles. The jet projectile contains weaponhead (WH) with a detonation device, mounted concentrically to transition section, the aerodynamic fairing with an elastic gap compensator, rocket engine (RE) with bottom, chamber and the outlet mouth, made of two identical half-rings aerodynamic stabilizer with the foldout blades and disclosing springs. WH is connected to the RE bottom through the cylindrical element of transition section with conical and cylindrical elements, at that the inner surface of the latest is in contact with collar, made at RE bottom, and d = 0,40,6÷ D, where d - diameter of the inner cylindrical element, D - inner diameter of the combustion chamber. At jet projectile shoting from the transport and firing box, the blades, placing with their ends in the radial grooves, are opened, turning on the axles by springs force. The interaction of spring hooks from the one hand with the blade edge, and on the other hand - with the surface of the groove, provides simultaneous opening of the blades until stop to the radial groove edge, and is held in such position by springs and air flow forces.

EFFECT: invention provides an increase of the range capability, reducing the flight weight and aerodynamic drag, increase of the aerodynamic stability margin and reduce of the aerodynamic asymmetry.
