Design and Test of an Air Cushion Field Dolly for UH/AH Helicopters

Abstract : The air cushion field dolly is an air-supported dolly without forward propulsion. Tests indicated that the dolly operated as intended up to helicopter gross weights of 7500 pounds. At helicopter gross weights above 7500 pounds the dolly operated satisfactorily on smooth ground, but required excessive drawbar pull on rough terrain. Although the dolly was capable of performing the desired mission, it was considered that it was too large and too complicated, relatively, for troop use in a forward area.
