STOL Tactical Aircraft Investigation. Volume 2. Design Compendium

Abstract

The design compendium presents methods for estimating the aerodynamic and stability and control characteristics of mechanical flaps and the three lift/propulsion systems: mechanical flaps plus vectored thrust, externally blown flaps, and internally blown flaps. A review of various theoretical approaches is presented to form a basis for the generalized methods that are developed to estimate lift, drag, pitching moment, downwash, and the lateral- directional stability derivatives. Sample problems are presented to allow the most advantageous utilization of the methodology. The data correlations shown at the end of the major sections verify and substantiate the selected approaches. A general methodology has been developed for predicting the low speed aerodynamic and stability characteristics of STOL transport aircraft. The methodology is applicable to the EBF, IBF, and MF/VT STOL concepts. The basic procedures, which predict the lift curve versus angle of attack, maximum lift coefficient, induced drag, thrust recovery, pitching moment, and downwash angle are easily hand-calculated for a single case or programmed on a small computer to calculate a large number of configurations.
