A Nonlinear Vertical-Plane Mathematical Model for Air Cushion-Supported Vehicles,

摘要

An analytical model for predicting the pitch and heave response of air-cushion-supported vehicles (ACV) during overland operation is developed. The effects of air compressibility and skirt contact with the supporting surface are included in the model. The resulting analytical model is used to predict the response of a JEFF (B) experimental model to periodically varying terrain. These predictions show excellent correlation with experimental model data, thereby serving as verification of the accuracy of the analytical model for a complete range of operating conditions for the JEFF (B).
