| Abstract: | A wall pressure correction method for closed rectangular subsonic test sections is presented. This paper gives the calculation of wall interference by method of influence function. Experimental examinations of the method give good results on high, lift measurements, as well as the blockage correction in the presence of a large wake region behind the model. The data provided by this paper are applicable for practical purpose. |
