... significantly better aerodynamic performance than optimizing stiffness alone. Improvements in the lift-to-drag ratio of up to 20% were achieved across multiple flight conditions. This study also identifies trends in optimal stiffness distributions and shows the potential for reducing torsional discontinuities...

... flight in cruise phase is the study case of the present article. Design/methodology/approach The standard lift-to-drag ratio (L/D) and flight dynamic models are established through flight data mining and the fuzzy logic modeling technique based on the flight data of quick access recorder available...

...Mustafa Kaya; Munir Ali Elfarra Purpose The critical Mach number, lift-to-drag ratio and drag force play important role in the performance of the wings. This paper aims to investigate the effect of taper stacking, which has been used to generalize wing sweeping, on those parameters. Design...
