ROTATING MISSILE Russian patent published in 2020 - IPC F42B12/44 F42B15/00 F42B10/16 

FIELD: military equipment.

SUBSTANCE: invention relates to military equipment and can be used in development of rotating missiles for various purposes, missiles of salvo fire systems. Rotary missile comprises head part with radial rounded front end and nozzle filled with liquid filler based on oil products, device for spreading and ignition of filler, missile engine with nozzle and tail unit with arched opening blades installed at an angle to longitudinal axis of missile. At the same time leading and trailing edges of empennage fins are made with one-way sharpening with skew located on their convex surfaces, with angle of 7°…10° in plane perpendicular to edges, and value of average pitch angle of fin ends is determined by dependence δ_av=(0.05…0.20)H_finb₀/d² F(m_fil/m_∑), wherein the rear edges of the arc-shaped blades in the root chord area are offset from the rear end of the missile engine towards the head part at distance of 0.05…0.25 of diameter of outlet section of missile engine nozzle and are installed with convex surfaces in direction of missile rotation so that their concave surfaces are windward.

EFFECT: invention enables to develop a rotating missile, which head part is filled with a liquid filler, with increased flight range due to reduced resistance of the head part and empennage, high efficiency and reliability of operation, improved accuracy and accuracy due to reduced aerodynamic loads and reduced spread of aeroballistic characteristics of missile in conditions of flight with increased speeds.
