1,155,314. Missile fins. DYNAMIT NOBEL A.G. 3 Aug., 1966 [3 Aug., 1965], No. 34875/66. Heading F3A. Missile 1 for firing from a tube 13 is provided with a fin divided into " mirror " symmetrical fin-halves which are each subdivided into parts 3 and 4 hinged together at 6 and 7 and to the casing of the missile, whereby, on launching the missile, a spring 8 brings the fin-halves together from the collapsed position shown into an erect position (Fig. 1, not shown) where they may be fastened together by a pin 11 and corresponding socket 12. A centrally, partly tapered stop 2 may be provided together with stops (not shown) on each of the hinges. Overhanging portions (14, Figs. 3 and 4, not shown) on the leading edge of one inner part 3 and the leading edge of the outer part of the other fin-half overlap the adjacent inner and outer parts of the erected fin to give a streamlined edge. |
