The report covers a research and development program to design and fabricate a prototype cargo-recovery parachute assembly for airdropping heavy unit loads in the order of 50,000 lb. The design study covers the trade-off analysis and cost effectiveness aspects for a complete parachute assembly. From these studies, a design analysis and complete detailed design were made based on the specified performance and design requirements. Use of data reduction on full-scale cargo drops with G-11A parachutes with vent-pull down configuration, scale model wind tunnel tests and parametric studies determined that it is feasible to use a cargo parachute of 135 ft. diam. with a vent-pull down in a cluster of six to recover a load unit of 50,000 lb.
