A boundary interference correction procedure based on solution of the Euler equations has been developed. The method computes free flight and wind tunnel flowfields, calculates the predicted force and moment differences between the two, and uses these force and moment increments to correct the experimental tunnel data. The resulting corrected data is a better approximation to the values one would measure on the vehicle in free flight than the original wind tunnel data. Data from tests in a tunnel where the blockage ratio is 2.664 % are corrected using the procedure and compared with data from tests where the blockage ratio is 0.17 %. The boundary interference corrections significantly improve the correlation between the two sets of data.
