- An analytical method has been developed by which the steady-state lift, pitching moment, and rolling moment produced by upper surface spoilers on wings can be predicted. Potential flow is assumed and a lifting-line theory is used, incorporating sectional characteristics calculated by a thin-airfoil theory. Sectional pressure distributions can also be predicted by a thick-airfoil theory. The only empirical data needed is the spoiler base pressure. Good agreement between predicted and measured values has been obtained.
