Abstract:

Presented are the results of the analytical study involving design optimization of the Active Arm External Load Stabilization System AAELSS, whose technical and operational feasibility was conclusively demonstrated under Contract DAAJ02-72-C-0046. The program consisted of two phases the analytical study, under which basic design parameters of the AAELSS were optimized, and the preliminary design phase of the improved system, under which a variety of different configurations were considered, including the conceptual design for the heavy lift helicopter HLH. The final design configuration, although specifically tailored to the CH-47C helicopters, contains basic design elements directly applicable to the HLH and represents a considerable design improvement over the experimental system.
