Evaluation of the C-130E Sability and Control Characteristics During Tandem, Sequential, and Single-Paltform LAPES Delivery and Airdrop Deliveries
Abstract
The purpose of these tests was to determine the stability and control characteristics and the structural integrity of the C-130E aircraft while performing various types of aerial deliveries. Low altitude parachute extraction system (LAPES) deliveries were conducted with single-platform, tandem, and sequential payload configurations. Airdrops were performed with single-platform payloads. It was determined that with proper pilot techniques satisfactory cargo deliveries could be made with all payload configurations up to a total payload weight of 50,000 pounds and that acceptable aircraft reactions and structural loads would result even if a failure in the extraction system caused a low extraction ratio delivery. An aim airspeed of 130 KIAS should be used for all heavyweight deliveries. With the techniques developed during the airdrop tests, it was estimated that the cargo jettison capability of the C-130E would be greatly increased over that shown in the Flight Manual. It was determined that if the forward load failed to extract during a sequential LAPES delivery, the aircraft could be safely climbed from the extraction zone, and be landed even if the aircraft center of gravity (cg) position moved as much as 7 percent forward of the Flight Manual published forward cg limit. Average extraction zone distance over 50-foot obstacles for heavyweight LAPES deliveries on a sea level standard day with no wind was 1,930 feet.
