Summary:Flight test puts forward higher requirements for air data test. Aiming at the limitations of traditional test methods, a new airborne optical air data system is developed to realize high-precision non-contact airspeed measurement. This paper mainly expounds the system composition and function module design scheme, introduces the laser Doppler velocity measurement principle and vacuum velocity vector signal calculation technology in detail, and carries out the ground and flight test verification respectively. Through data analysis, the optical atmospheric data system is stable in state and normal in function, and each index of test data can meet the requirements of model task test. During the test, we have accumulated rich experience in system installation, calibration and data analysis.
