Abstract : This report presents the results of a test program conducted to investigate the feasibility of a two-stage, platform-mounted airdrop system. Nineteen platform airdrop tests were conducted from C-130 aircraft. Tests were conducted at an indicated airspeed of 130 or 150 knots. Tests were initiated at mean sea level (MSL) altitudes ranging from 8,060 to 10,620 feet. The extracted weight of the loads ranged from 2700 to 15,200 pounds. Displacements, velocities, event times, and photographic coverage were obtained on all tests. Selected forces on components in the test system were measured on all but one test. The most significant problem encountered during this program was test load oscillation during first stage descent. Recommendations are made on methods employed to reduce test load oscillation.
