No more than 1mm thick at the leading edge of an airfoil, and grows in thickness as it moves aft over the surface. STABILITY AND CONTROL OF STOVL AIRCRAFT: THE DESIGN OF LONGITUDINAL FLIGHT CONTROL LAWS Chris Fielding, Matthew Lodge through its application to high performance conventional take-off and landing (CTOL) combat aircraft, from the Tornado [1] STABILITY AND CONTROL OF STOVL AIRCRAFT: THE DESIGN OF LONGITUDINAL FLIGHT CONTROL LAWS .

    Abstract energy levels for fighter aircraft. Especially for The X flight control system enables flying at very high angles of attack, including the poststall regime. This not only offers extreme maneuverability, but also the capability for a steady slow flight. This feature can also be . You can write a book review and share your experiences. Other readers will always be interested in your opinion of the books you've read. Whether you've loved the book or not, if you give your honest and detailed thoughts then people will find new books that are right for them.

    Jay M. Brandon, Dynamic Stall Effects and Applications To High Performance Aircraft, Special Course on Aircraft Dynamics at High Angles of Attack: Experiments and Modelling, Hampton, Virginia, AGARD-R, March, As the speed of the aircraft increases, the wings are swept back. At the highest speeds, in the supersonic regime, the wings are fully swept back for optimal performance. The ability to change wing sweep while in flight is an extreme example of morphing reserved for high-performance military aircraft.

Eigenstructure control involves modification of both the eigenvalues and eigenvectors of a system using feedback. Based on this key concept, algorithms are derived for the design of control systems using controller structures such as state feedback, output feedback, observer-based dynamic feedback, implicit and explicit modelfollowing, etc.
