The low speed test limit of VSTOL aircraft wind tunnel testing has been investigated and two wall correction theories currently in use have been analyzed. The models used were either rotors or propellers acting as a rotor. In general the test limit based on tail data is more stringent than limits based on rotors. Corrections using Heysons X sub eff are more accurate than traditional wall corrections. Author
