ROCKET STABILIZER Russian patent published in 2023 - IPC F42B10/16 

FIELD: rocket technology.

SUBSTANCE: invention relates to rocket technology and can be used in the development of stabilizers for multiple rocket launchers. The projectile stabilizer contains arcuate drop-down blades (1) with lugs (2), a cylindrical fairing (3) with grooves for wedge-shaped retainers (4). The leading edge of each blade (1) is made with a broken contour and consists of a lower (5) part adjacent to the fairing (3), with a sweep angle relative to the normal to the longitudinal axis of the fairing, not exceeding 5°, and a length of 0.3…0.6 of the sweep height of the blade and the upper (6) part with a sweep angle with respect to the fairing normal equal to 10°…35°. The thickness of the blade in the end part is 0.25…0.60 of its thickness in the region of the root chord. The thickness of the fairing (3) is taken equal to 0.5…1.0 of the blade thickness in the region of the root chord. The length of the groove of the wedge-shaped clamps (4) is 5…10 of the thickness of the fairing (3) at the point of its contact with the lugs of the blades (1).

EFFECT: creation of a PC stabilizer is provided, which allows to increase the flight range, increase the reliability of operation, improve the characteristics of accuracy and accuracy of fire by reducing the spread of the stabilizer drag coefficient and the lift of arcuate blades, improve aeroballistic characteristics by reducing the effect of aeroelastic disturbances on structural elements.
