Design and performance of a parachute recovery system to recover 155-mm- and 8-inch-diameter artillery shells
A parachute recovery system has been developed and demonstrated for the recovery of 155-mm- and 8-inch-diameter artillery shells. The recovery system functions after being subjected to gun launch accelerations of up to 18,000 g's axially and up to 400,000 rad/sec/sup 2/ radially. The parachute is deployed while the shell is still spinning at about 250 revolutions per second. To deploy the parachute while the shell is spinning, a double-swivel system was developed. The deployment signal for the recovery system is provided by an electronic timer. Over 250 tests have been performed on both the 155-mm- and 8-inch-diameter artillery shell. Impact velocities are between 100 and 120 feet per second. The latest version of the recovery systems has been proven to be over 95% successful for the recovery of 8-inch-diameter artillery shells and over 85% successful for the recovery of 155-mm-diameter artillery shells.
