Abstract: A wall pressure signature correction method is developed to detennine the semiempirical correction factors suitable to the similar geometric model in a typical test attitude,in order to correct the wall interference on the model in other tested attitudes with a high angle of attack.In this way the correction procedure for the high angle of attack model tested is as easy and convenient as a semiempirical method,meanwhile it remains accurate enough comparing to the standard wall pressure signature method.The demonstrations with two sets of models pres-ented indicate good results.
