Abstract
1,227,414. Fin-stabilized-projectile launcher. TAMPELLA A.B. OY. 26 March, 1968 [1 April, 1967], No. 14463/68. Heading F3C. A fin-stabilized-projectile launcher having a smooth-bored barrel which is closed at its rear end has annular slots at its muzzle end (Fig. 1, not shown) or is provided with a muzzle attachment 2c of hollow open-ended cylindrical form, the wall of the attachment 2c being slotted. The slots enable at least some of the propulsive gases to expand while the projectile is still under guidance in the launcher. The annular grooves may be helical. The muzzle attachment as shown comprises a stack of annular discs 7 having spacing members 8 interposed therebetween the stack being provided with end members 9, 10 and the whole assembly being secured by anchor bolts 11. The bores in the discs 7 and spacing members 8 through which the bolts 11 extend are, in one position, radially extended such that longitudinally extending locking rods may be passed through the stack to secure the spacing members against relative rotation (Fig. 3, not shown). The spacing members 8are of tear drop shape. In a modification each spacing member has a portion at the outer periphery of the muzzle attachment parallel with the axis of the attachment to lock the spacing members against relative rotation (Figs. 4, 5, not shown).
