Wind Tunnel Measurements at M = 1.6 of the Aerodynamic Effects of a Root Gap on a Control Surface of Square Planform Mounted on a Body.
Abstract
Increasing the root gap from 0.4% to 9.9% span reduces the normal force for small angles of incidence of the body and zero control surface deflection by between 5% and 10% but has little effect for zero angle of incidence and small control deflection. The center of pressure moves forward by about 0.5% chord and outboard by about 5% span with increase of the gap for small angles of either the body or the control surface, though the spanwise change for zero control deflection differs for the two lengths of body tested.
