Approximate Method for Predicting Supersonic Normal Force Coefficient of Very-Low-Aspect-Ratio Lifting Surfaces

摘要

A simple, empirical method has been developed for predicting at supersonic speeds the normal force coefficient, C(N), (including carryover) of very-low-aspect ratio lifting surfaces mounted on bodies of revolution. Predicted values of C(N) using this method are shown to be in good agreement with test data obtained on both thick and thin surfaces, at Mach numbers from about 2.5 to 7.7 and angles of attack to 24 degrees.
