Wake Survey of Airplane and Passenger Car Models

A simple wake survey method was applied to the flow fields after an airplane model and a passenger car model. The method consists of a rake of four simple total pressure probes, a traverse mechanism and a personal computer. The measurement can be automatically conducted by their combination. The model airplane is of FA-200 of Fuji Heavy Industries and the car model is of Supra of Toyota Motor. The measurements are made at various conditions changing flap angles, angles of attack. In case of the car, yaw angles were changed and the body shapes were changed into fastback, squareback and wagon by changing several attachments. The obtained results were compared with the aerodynamic forces measured by a struttype balance and presented good explanation of the measured aerodynamic forces.
