Evaluation of the Modified Forward HMMWV Lift Provision in Dual Side-By-Side Airlift Configurations.

摘要

Field modifications to U.S. Army External Airlift Transport (EAT) operating procedures became critically necessary during Operation Desert Storm. To meet mission essential objectives, the U.S. Army 101st Airborne Division developed a new dual side-by-side (DSS) airlift sling configuration for air-lifting two high mobility multipurpose wheeled vehicles (HMMWV) simultaneously with a CH-47D helicopter. The U.S. Army Materials Technology Laboratory performed experimental and finite element analysis (FEA) activities to evaluate the performance of the forward outboard HMMWV lift provision subjected to DSS sling configurations. These activities were performed at the request of the Natick Research, Development, and Engineering Center in an attempt to certify two DSS airlift configurations under consideration for further use. Results of both the experimental and analytical analyses were obtained, discussed, and subsequently correlated. Conformity of the provision to Military Standard 209-G, Slinging and Tiedown Provisions for Lifting and Tying Down Military Equipment was evaluated for both configurations.
