An investigation was conducted to determine the lateral-directional characteristics of a 1/10-scale free-flying model of a variable-sweep fighter airplane at high angles of attack. The flight tests were conducted in the Langley full-scale tunnel and included steady flight at high angles of attack, 1g stalls, and studies of various piloting techniques for lateral control at high angles of attack. In addition, flights were made to evaluate the effects of artificial angular rate stabilization in yaw and roll. Tests were conducted for wing-sweep angles of 22 deg, 35 deg, 50 deg, and 68 deg. Static and dynamic (forced-oscillation) wind-tunnel force tests and theoretical calculations of dynamic stability characteristics were also made as part of the investigation.
