Abstract

A tactical vehicle should have air transportability for rapid attack and should satisfy its basic role for ground transportation. Airlift provision must be developed for aerial transportation of tactical vehicles by helicopter. The design points of front and rear lifting devices should be constructed, and the sling loads should be calculated according to various flight conditions to maintain a stable position in the air transportation of a military vehicle. The sling loads that act on the design points of airlift provision can be calculated by the analytic method defined in MIL-STD-209K. However, the actual sling loads could be different from theoretical sling loads due to vehicle specification, airlifting mechanism, and flight environment. Therefore, a virtual analysis environment for the development of airlift devices should be constructed. To establish an optimal design of airlift provision, accurate sling loads should be calculated through flight simulation, and the base model of airlift provision should be constructed based on calculated loads. In this study, we proposed an integrated process for the selection of design parameters, design of experiment, and approximate optimal design of a Korean light tactical vehicle with lightweight airlift provision.
