Abstract : The purpose of the study was to develop an analytical procedure which can be used to predict the static performance of an Air Cushion Landing System in the vertical direction. A mathematical model of an ACLS was developed which interrelates the system variables used to describe the force balance, the flow balance, and the geometric constraints which exist in the static mode. Since the mathematical model yielded only nine equations in thirteen unknowns, four additional equations were generated from experimental data taken from scale models of an ACLS-equipped CC-115 aircraft. Experimental values of trunk pressure, cushion pressure, and ground clearance at different gross weights for both floor-in and floor-out conditions are required as inputs to the prediction procedure.
