Abstract:

An investigation to determine experimentally the minimum size and optimum type of parachute for stabilizing general aerial delivery cargo and more specifically, the A-22 Cargo Container, was conducted. A 4 ft ribless guide surface parachute in connection with a riser at least 10 ft long represented the desired optimum. A 64 in. ribbon parachute with 20 geometric porosity in connection with a minimum riser length of 10 ft appeared also to be quite satisfactory. In addition, the investigation provided sufficient data for the calculation of trajectories for different configurations and release conditions.
