This report presents the results of a program for the design, fabrication, test, and demonstration of two identical engineering models of the Helicopter Ground Mobility System HGMS. Task 1 resulted in a complete, detailed and documented design for the HGMS prime mover, skid-equipped helicopter adapter, and flotation track assemblies. In Task II, the design was converted into hardware which, along with a device simulating the wheel-equipped UH-60A Black Hawk and YAH-64 AAH helicopters, was tested in Task 3 to demonstrate compliance with the requirement and specification for the HGMS. Minor changes, the need for which emerged from the test activity, were incorporated in the engineering models and design data during Task 3. In Task 4, the contractor prepared assessments of HGMS reliability and maintainability as well as estimates of requirements for logistics support. The total program described in this final report produced systems which clearly indicate that Army helicopters, both wheeled and skid-equipped, can be successfully transported between a forward area landing zone and a concealed larger area with no surface preparation and with a minimum of equipment an personnel. Moreover, the program demonstrated that a lightweight and helicopter-transportable HGMS answers the Armys long-standing need for helicopter ground mobility.
