Abstract : This report describes a method for application of the WES VCI/RCI (Vehicle Cone Index/Rotating Cone Index) criteria to helicopters and related ground support equipment. Through the use of ground mobility submodels developed by WES and the soil strength requirements determined for one helicopter (CH-47A), comparative performance capabilities are determined on the basis of wheel sizes and loads and sinkage into the ground. Estimates are made of the performance requirements of the AH-56A helicopter, and the application of drawbar-pull capabilities of selected ground vehicles to towing the AH-56A are presented.
