Abstract

1,242,029. Projectile tails. FORENADE FABRIKSVERKEN. 18 July, 1969, No. 36234/69. Heading F3A. A stabilizing tail for a gas-driven non-spinning projectile, comprises a tube 1, Fig. 1, having groups of slits arranged around its periphery, each group consisting of one longitudinal slit 5 terminated by two transverse slits 3 and 4 in a letter H or a letter U pattern, the ends of the transverse slits remote from the longitudinal slit being connected by weakings (not shown) so as to define a number of tongues 6 and 7 that fold radially outwards under the action of the remaining driving gas pressure in the tail after the projectile has been launched. Adjacent tongues can clap together to form a radially directed fin 13, Fig. 6. The tail has a full-calibre threaded portion 11 for connecting it to the projectile 2. The remaining portion of the tail is sub-calibre, whereby the driving gas pressure on the inside and the outside of the tail is equalized whilst the projectile is within the launching device 9.
