High-speed aircraft may have unsatisfactory stall characteristics and the aircraft may be lost because of the uncontrolled flight gyrations encountered in attempting to maneuver in the stalled flight regime. Results are presented of a study to determine the feasibility of using a captive technique in a wind tunnel to study aircraft post-stall characteristics and to define boundaries for maintaining controlled flight of the aircraft. The technique appears feasible but needs to be developed by conducting pilot tests in an existing facility.
