Abstract:

The report presents highlights of a recent survey of the future needs for dynamic stability information for such aerospace vehicles as the space shuttle and advanced high performance military aircraft, indicating the importance of obtaining this information for high-angle-of-attack high-Reynolds-number conditions. A review of the wind-tunnel capabilities in North America for measuring dynamic stability derivatives, reveals an almost total lack of such capabilities for Mach numbers above 0.1 at angles of attack higher than 25 degrees. In addition, capabilities to obtain certain new cross-coupling derivatives and information on effects of the coning motion are almost completely lacking. Modified author abstract
