Study on prediction of ground effect test data

Based on the incompressible potential flows theory of low speed wind tunnel test, for the test of aircraft ground effect,a method is proposed to calculate and obtain the correspond-ing data for different floor heights of floor from the test data without the floor.The validity of the method is demonstrated by comparing the calculated results with the test data.Meanwhile, correcting the calculated results corresponding to existing test data with the floor can decrease the error of the data predicted by the method.
