An Investigation of the Low Speed Stability and Control Characteristics of Swept-Forward and Swept-Back Wings in the Ames 40- by 80-Foot Wind Tunnel

Abstract

Results of tests on large-scale highly swept-back and swept-forward wings with angles of sweep of zero and plus or minus thirty and forty-five degrees are given. Various flap positions and angles of slip are considered. Primary problems were loss in maximum lift, high effective dihedral, and reduction in lateral control. Graphs show aerodynamic characteristics of all models tested and aerodynamic results of tests. Large-scale results approach small-scale results with increasing angles of sweep.
