The invention belongs to the technical field of wind tunnel tests, and discloses a flutter characteristic test device and test method for a skin panel of a high-speed aircraft. The test device comprises a backpressure cavity, an electromagnetic valve, a backpressure cavity pressure sensor, a control system and an air pressure servo system. The backpressure cavity and the air pressure servo driving system control the pressure difference between the two sides of the skin panel model, the pressure of the backpressure cavity is controlled in real time according to the wind tunnel incoming flow Mach number and the static pressure of the test section, it is guaranteed that the pressure difference between the two sides of the skin panel model is a given numerical value, and the device is suitable for carrying out a side wall supported high-speed aircraft skin panel flutter characteristic test. According to the test method, the pressure difference between the two sides of the wallboard flutter model is given according to the flight condition of the high-speed aircraft, an instruction is sent to the pneumatic servo system through the control system, the pressure of the backpressure cavity is adjusted by changing the volume of the backpressure cavity, and the pressure of the backpressure cavity is adjusted in real time according to the static pressure change condition of a flow field of a wind tunnel test section in the test process. And the accuracy of test data is ensured.
