Abstract:
A flow field calibration facility based on high pressure mass flow p.V.T.t method and the comparing method(hereafter referred to as on-line calibration facility)was designed to meet the urgent demand of air-breathing engine testing system to achieve accurate measurement and field calibration of high-pressure large flow supersonic air.By integrating the primary p.V.T.t method and the secondary standard-sonic nozzle,this facility effectuates calibration,traceability and accurate measurement of air flow coefficient of the sonic nozzle under the conditions of pressure range of 3～23 MPa and flow range of 1～60 kg/s.The extended uncertainty of the on-line calibration facility is 0.84%.
