SHELL BASE FOR CARRIER MISSILES

摘要

The base plate (23) of a shell base (20) for a carrier missile, with a cavity (26), for example for a parachute, on the side farther from the rear of the missile may be bent axially when the missile is fired. This results in radial constriction of the base envelope (22) and loss of contact between the guide strip (27) on the envelope (22) and the barrel of the weapon and frequently leads to escape of gas. To prevent the above-mentioned radial constriction in the region of the guide strip, the shell base (20) has a base plate (23) convex toward the rear of the missile. As a result of the convexity of the base plate (23), when the missile is fired a radial expansion occurs which ensures that the guide strip (27) remains gastight and transmits torsion even at high gas pressures.
