Analyses and design studies have been conducted to determine the characteristics of an Air Cushion Landing System ACLS as it would be applied to an Advanced Medium STOL Transport AMST equipped with mechanical flaps and a vectored thrust powered lift system. It was determined that an ACLS would be feasible on an AMST type airplane, but requires a special housing arrangement which broadens the ACLS footprint area when it is deployed. Furthermore, special provisions are needed for ground handling and parking. Because it eliminates some of the concentrated loads associated with conventional landing gear, and is easily faired for low drag when retracted, the ACLS would permit a noticeable reduction in aircraft empty weight for a given mission requirement, if structural provisions for conventional landing gear are not included in the airframe. Substantial uncertainties remain unresolved especially with respect to aircraftair cushion landing dynamics and spraydebris effects.
