Abstract: To solve the real vehicle test’s difficult problem of the flow field and the flow velocity and the air content of the amphicar’s hydraulic propeller, a test method was studied and a sensor was manufactured. According to the theory of the hydrodynamics, a resolution was executed on hydraulic propeller’s spout and probe-style’s flow velocity and the air content sensor, and the piezoresistive flow velocity sensor and the electrode plate air content sensor were manufactured after analyzing the problem’s main reason. The test indicated that this technology could solve the existing flow rate test sensor or instrument unable using problem arising from the fierce shaking and the narrow space around the hydraulic propeller and the actual flow field cannot be damaged while testing. The real vehicle test technology of the flow rate and the air content of the amphicar’s hydraulic propeller were implemented on some amphicar and the test precision was satisfied.
