Abstract:By investigating the advanced technology of surface pressure distribution test and calibration in the world, the current status of testing and calibration of steady and dynamic pressure distribution tests in wind tunnel is introduced. The representative techniques such as pressure scanning valve and pressure sensitive paint (PSP) in distributed pressure test are selected to illustrate, and the key elements of calibration test including calibration theory, test process and traceability are discussed. By comparing the current situation of calibration technology for wind tunnel pressure measurement at home and abroad, the problems and solutions of calibration for pressure test in China are analyzed, and the development direction of wind tunnel pressure distribution measurement and calibration technology in China in the future is put forward.
