The invention provides a propeller testing device and method, and the device comprises a vacuum chamber, and a fixed rack, a measurement assembly, a main shaft, a middle connector, a propeller clamp, a pitch changing mechanism and a power mechanism which are disposed in the vacuum chamber. The measuring assembly is arranged on the fixed rack, and a sensor of the measuring assembly is connected with a data interface in the surface of the vacuum bin and used for collecting rotation data of the propeller; the main shaft is arranged on a connecting plate of the measuring assembly; the middle connector sleeves the main shaft and is rotationally connected with the main shaft; the paddle clamp is arranged at the end part of the middle connector and can rotate; the pitch changing mechanism is arranged on the main shaft and used for driving the paddle clamps to rotate; the power mechanism is arranged on the main shaft, and the output end of the power mechanism is connected with the middle connector. According to the propeller testing device and the propeller testing method provided by the embodiment of the invention, the vacuum bin does not need to be opened and closed for many times, the rotation data under different attack angles can be quickly acquired, the bin opening frequency can be effectively reduced, and the testing efficiency can be improved.
