Abstract : Configuration design, analysis, and wind tunnel test of a vane-type multi-function air data probe (MFP) was described. First,
numerical analysis was conducted for the initial configuration of the MFP in order to investigate aerodynamic characteristics.
Then, the design was modified to improve static and dynamic stability for better response characteristics. The modified
configuration design was verified through wind tunnel tests. The test results are also used to verify the accuracy of the
analytical method. The analytically estimated aerodynamic damping provided by the Navier-Stokes equation solver correlated
well with the wind tunnel test results. According to the calculation, the damping coefficient estimated from ramp motion
analysis yielded a better correlation with the wind tunnel test than pitch oscillation analysis.
