SIMPLIFIED APPROXIMATIONS OF INTERFERENCE EFFECTS ON JET V/STOL AIRCRAFT.
Abstract
A semi-empirical approach is used to predict performance losses and pitching moments caused by interference effects on different aircraft planforms in hover and transition. Different aircraft planforms, and variation of the jet exhaust combinations make the problem of predicting interference effects difficult. The induced flow that causes the performance losses in hover is superimposed on the free stream flow to determine the interference effects on performance and pitch during transmission. An empirical factor is used to correct for the compressibility and temperature effects of the jet exhaust on the induced flow. Results are computed on the IBM 7094 computer. (Author)
