Abstract

903,842. Tin assemblies for rotated projectiles. BOMBRINI PARODI-DELFINO S.p.A. March 26, 1959 [April 4, 1958 (2)], No. 10537/59. Classes 9 (1) and 9 (2). A collapsible tail assembly for rotated rocket projectiles is mounted by means of ball bearings around the nozzle, so that the rotation of the projectile is not communicated to. the tail during flight. The divergent part 16 of the nozzle is screwed on to the convergent part 18 and has external seatings for ball races 1, 2 carrying a sleeve 3. Slidably secured within the ring 3 by rotatable studs 5 is a bush 7, wings 6 being secured by swaging to the outer ends of the studs. Each wing 6 is partly housed in a milled slot in the ring 3, Fig. 2, and is engaged by a pivot-pin 10. Longitudinal slots 11 guide the studs 5 as the wings move to the extended position. A ring 12 holds the ring 3 in place. A plugged hole 15 is provided for the insertion of the ballbearings 2. On launching the rocket from a tube, the propellent gases issuing from the nozzle impinge on inclined vanes 14 and thus cause the rocket to rotate. Due to inertia, the bush 7 moves counter to the rocket's rotation and in consequence as it slides rearwardly, the studs 5 cause the wings 6 to rotate about the pins 10 to the extended position in which they impinge on the bottom of the slots 8.
