ABSTRACT:
A fin stabilized projectile in which measures are taken for increasing the thermal resistance of its guide fins against the uncontrollable danger of burning or melting due to overheating of the material as a result of air friction during the flight of the projectile. Each guide fin is composed, at least in the region of its leading edge of a heat resistant fiber material or a heat resistant composite fiber material. The fins may be composed entirely of the heat resistant material or the leading edges of the fins, the leading and outer edges of the fins, or the entire front fin portion may be configured as a strip of the fiber material in front of and fastened to a metal body member comprising the remainder of the respective guide fin. Moreover, the connecting region between any such strip and the metal body member is preferably configured with a sloped, and thus as a contact area which has a larger surface area. The strip is glued, riveted and/or screwed to the body member in the connection region. Furthermore, the fins are attached to the projectile by any one of the disclosed embodiments.
