• Abstract:
  The results of an experimental and theoretical investigation of the longitudinal aerodynamic characteristics of a tracked ram air cushion vehicle are presented. Experiments have been conducted both in a wind tunnel with a model and section of guideway and with the same model propelled along a 300-foot guideway. Experimental results are presented for the dependence of the lift, drag, and pitching moment of the model-on-model height above the guideway and winglet gap, providing basic data necessary for the analysis of longitudinal stability and ride qualities of the concept. The stability derivatives determined from the moving-model experiments have agreed well with the wind tunnel results. A theory is presented which shows good agreement with the experimental results for the stability derivatives.
