The invention provides a pulsating pressure test system for a rotary impeller of a water-jet propulsion hydraulic model to meet the requirement of pulsating pressure test of the rotary impeller of thewater-jet propulsion hydraulic model. According to the test system, based on a water-jet propulsion hydraulic performance test hydraulic system,a pressure sensor is arranged on a blade of a rotary impeller; An electrical connector fixed in an inlet flow guide cap is connected with an output cable of a pressure sensor and a connecting cable in an impeller shaft, and the connecting cable is connected to a data acquisition and analysis system, so that the pressure sensor, the data acquisition and analysis system and the device synchronously rotate in the operation process; Real-time measurementof the pulsating pressure of the rotary impeller of the water-jet propulsion hydraulic model is achieved. The pulsating pressure test system has the advantages of being exquisite in structure, high inoperability and the like.
