A wind-tunnel test is performed on a 1 20 scale model of a supersonic aircraft. The prototype aircraft flies at 480 m/s in conditions where the speed of sound is 300 m/s and the air density is 1.0 kg/m3. The model aircraft is tested in a wind tunnel in which the speed of sound is 279 m/s and the air density is 0.43 kg/m3. The drag force on the model is 100 N. What speed must the flow in the wind tunnel be for dynamic similitude, and what is the drag force on the prototype?
