Basic aerodynamic coefficients for the Tracked Air Cushion Research Vehicle (TACRV) are developed by analysis of data obtained during wind tunnel tests of a 1/10 scale model. Vehicle lift and drag are found to be primarily a function of the dynamic pressure to average cushion pressure ratio. Vehicle lift is 8370 lb at 300 mph (11,900 lb in a 60 mph crosswind at that speed), well below the vehicle cushion supported weight of 51,950 lb. Vehicle drag is 7920 lb at 300 mph; drag levels can be reduced 10-15 percent with an aft streamline tail fairing. (Author)
