AIR FORCE FLIGHT DYNAMICS LAB WRIGHT-PATTERSON AFB OH
Static load deflection tests and vertical drop tests were performed on a quarter scale model of a Canadian CC-115 Buffalo aircraft equipped with an Air Cushion Landing System ACLS. The model weighed 610 lbs and the ACLS air supply was furnished by two electric fans. The static load deflection tests showed that the model weight could be increased from 610 lbs to 1310 lbs before the fans stalled. The model deflection one inch when 560 lbs were added to it during hover over a solid surface. The portion of the weight supported by the trunk instead of the cushion increased from 3 at 610 lbs to 24 at 1310 lbs.
