ADAPTIVE DEFLECTION OF WING NOSE FLAP OF COMBAT TRAINING AIRCRAFT AND ITS IMPACT ON FLIGHT RANGE AND DURATION

Abstract

In this article presented the main result of numerical investigation of ability to improve the aerodynamic perfection of modern combat training aircraft. To determine the aerodynamic characteristic was used the discrete vortex method with closed vortex frames. In the work was presented the algorithm of a deflection of mechanization of a wing for increase of aerodynamic quality of the aircraft. The calculation of flight range and duration was at incremental extension and at realization of adaptive deflection of nose flap for Mach number M < 0.6.
