TAIL FINS OF SPIN-STABILIZED MISSILE Russian patent published in 2002 - IPC

FIELD: missiles whose spinning in the flight path is ensured by the tail fins, applicable in development of salvo-fire missile systems. SUBSTANCE: the tail fins of a spin- stabilized missile has a thin-walled shell with stabilizing surfaces with struts fastened on it. The shell has external annular bulges with openings accommodating the struts, and positioned in them, under the shell along the root edges of the stabilizing surfaces are the axles of the stabilizing surfaces made in the form of tie rods with inclination to the missile longitudinal axis of the missile in the direction of its spinning. The tie rods are provided with a tensioning device, and their number is multiple of the number of the stabilizing surfaces. EFFECT: enhanced reliability of functioning, ensured the best quality of construction at an angular rate of missile spinning in the flight path exceeding 15 rps. 2 dwg
