This novel research evaluates how an adaptive winglet can improve an aircraft flight performance. A one-rotation axis adaptive winglet was designed and applied to the CRJ700 aircraft. Then, using a validated aerodynamic model, several winglet deflection angles were analyzed for several flight conditions of the CRJ700. The paper shows that the lift-over-drag ratio or the fitness of the aircraft was improved by up to 5.42% using an adaptive winglet for typical CRJ700 cruise conditions. Finally, it was simulated aerodynamic performance during a cruise performed at Mach number 0.75. This research shows that the adaptive winglet allows a regional aircraft such the CRJ700 to improve its cruise performance in terms of lift, drag of lift-to-drag ratio. Moreover, it has shown that the adaptive configuration allows to customize the optimization criteria in flight, which is an interesting advantage.

Abstract
This novel research evaluates how an adaptive winglet can improve an aircraft flight performance. A one-rotation axis adaptive winglet was designed and applied to the CRJ700 aircraft. Then, using a validated aerodynamic model, several winglet deflection angles were analyzed for several flight conditions of the CRJ700. The paper shows that the lift-over-drag ratio or the fitness of the aircraft was improved by up to 5.42% using an adaptive winglet for typical CRJ700 cruise conditions. Finally, it was simulated aerodynamic performance during a cruise performed at Mach number 0.75. This research shows that the adaptive winglet allows a regional aircraft such the CRJ700 to improve its cruise performance in terms of lift, drag of lift-to-drag ratio. Moreover, it has shown that the adaptive configuration allows to customize the optimization criteria in flight, which is an interesting advantage.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
