Wind Tunnel Testing of an Advanced Flying Automobile Concept

A 1:12 scale model based on the Sokol A350 Advanced Flying Automobile Concept was examined in the San Diego State University Low Speed Wind Tunnel for performance and stability characteristics. Observation showed that the model stalled at angles of attack above 12 degrees, corresponding to a maximum coefficient of lift of 1.54 and a drag coefficient of .284 for the wing center position. Analysis of the moments revealed that the test model was unstable with the current design specifications, however varying the wing location provided additional insight on the stability of the model. With design changes based on moving the center of gravity forward, the prototype vehicle is capable of creating enough lift to fly safely.
