Abstract : In order to resupply containers at higher airspeeds and from lower altitudes, the High Speed Container Delivery System (HSCDS) program was initiated in 1990. This system will be designed to airdrop from the C-17, MC- 130, and other capable aircraft from up to 250 knots indicated airspeed (KIAS) and as low as 300 feet above ground level (AGL). In November 1991, a Trade off Determination (TOD) was started by Natick to be conducted simultaneously with the Trade off Analysis (TOA) being prepared by the U.S. Army Quartermaster School. The TOD was prepared in-house; whereas, the TOA was performed by a contractor (American Power Jet). The HSCDS consists of three separate subsystems; therefore, the TOD was prepared accordingly. The results of the TOD indicated that: (1) Breadboard prototypes of rigid and cargo net containers need to be designed, constructed, and tested before one concept is chosen over the other.( 2) A 40 to 50 foot diameter flat circular solid cloth parachute that utilizes a lower porosity canopy material near the apex seems to be he most promising alternative for the main recovery subsystem. (3) Aerodynamic parachute) method of extraction/ejection of containers seems to have the most potential for success.
