Separation test system and method based on high-Mach-number wind tunnel high-clogging-degree test piece

The invention discloses a separation test system and method based on a high-Mach-number wind tunnel high-clogging-degree test piece. A pressure measuring point in a wind tunnel plenum chamber measures the pressure of the wind tunnel plenum chamber and feeds back a pressure value to a pressure acquisition system; a test piece is installed on the attack angle mechanism, and a separation unlocking device is arranged on the test piece; the pressure intensity acquisition system is connected with the pressure intensity measuring point and the separation unlocking device control system, receives the pressure intensity value, judges whether the pressure intensity value meets an unlocking condition or not, and sends an unlocking signal to the separation unlocking device control system when the pressure intensity value meets the unlocking condition; the separation and unlocking device control system is connected with the separation and unlocking device and sends an unlocking signal to the separation and unlocking devic
