The high-angle-of-attack testing intended to develop leading-edge modifications for tailoring the stall characteristics of model is described. Two different leading-edge modifications are considered: a small profile leading-edge droop on the outboard 24 percent of the wing and a large profile leading-edge droop on the outboard 50 percent of the wing. Results indicate that the longitudinal stability for the unmodified and both modified configurations was good for low angle of attack, but the modified configurations exhibited neutral longitudinal stability just prior to stall. The unmodified and both modified configurations demonstrated good lateral stability characteristics for low angles of attack, but all configurations were directionally unstable for high angles of attack.
