[0003] A flying car is a vehicle that combines the functions of a car and an aircraft, capable of driving on land and flying in the air. It can change its shape and drive on the road like a traditional car, but it can also unfold its wings and propulsion system to fly in the air. Because flying cars can exert their unique advantages in many fields and have huge development potential, more and more countries have increased their attention to them. Flying cars have become the focus of research among countries and may trigger a great technological revolution.

[0043] Support platform 200, for assembly on the ground or on a building;

[0044] A flight dynamics test unit 300 , mounted on the support platform 200 , is used to perform flight dynamics testing;

[0045] Multiple natural wind simulation assemblies 100 are annularly slidably assembled on a support platform 200, and are used to provide natural winds of different speeds from different angles to the flight power test unit 300;
