Abstract : The Pioneer Para-Commander Mark 1 24-ft. diameter parachute was tested. A total of 246 tests was made using a B-66, a C-130, a C-47 and an H-21 aircraft. Launch velocities varied from minimum (near-zero) to 225 KCAS and launch pressure altitudes ranged from 1000 to 35,000 ft. Articulated and torso dummies weighing 283 lb (gross weight) were used for 82 dummy drop tests. Test parachutists weighing from 181 to 241 lb (gross weight) made 164 live jumps. Parachute opening times, fall distances, glide ratios, turn times and live-jump reliability data were obtained. The test item was determined to be safe for Air Force use when used by qualified and experienced free-fall parachutists. Recommendations are made for modifications, packing procedures and live jump procedures. It is also recommended that launch altitude should not be less than 1000 ft above ground level with a one-second delay to pack opening, nor should the parachute be deployed above 150 KCAS at 1000 ft pressure altitude. It is recommended that additional dummy tests be conducted to determine maximum safe opening velocities above 1000 ft altitude.
