Effects of High-Lift Devices on V/STOL Aircraft Performance. Volume I

Abstract

The purpose of the study was to develop a unified analytical procedure to evaluate the effects of passive high-lift devices on deflected- slipstream or tilt-wing V/STOL configurations. Methods were developed to predict the two-dimensional flapped airfoil characteristics to be used in a span load program. The span load results are used in procedures for estimating the coefficients of lift, longitudinal force, and moment for a wing partially immersed in a propeller slipstream. These characteristics can then be used in a performance program developed to calculate the takeoff, landing, and transition maneuvers. In addition to these tasks, investigations were made into downwash characteristics, wind tunnel wall corrections, and correlations of flight test data with theory. An analysis of the effects of high-lift devices on the performance of a tilt-wing V/STOL configuration is included in the appendix.
