Aerodynamics of a wing body with different Winglet Cant Angle [PDF]

open access: yesE3S Web of Conferences
Current aircraft was designed with winglet at the tip. Winglets reduce the drag and improve fuel efficiency and range. The winglets have been in use for nearly 90 years, but it have been remained fixed.

Tip gap size effects on thermal performance of cavity-winglet tips in transonic turbine cascade with endwall motion

open access: yesJournal of the Global Power and Propulsion Society, 2017
The thermal performance of two cavity-winglet tips with endwall motion is investigated in a transonic high pressure turbine cascade, which operates at an engine representative exit Mach number of 1.2 and an exit Reynolds number of 1.7 × 106.

Integrated Design of a Morphing Winglet for Active Load Control and Alleviation of Turboprop Regional Aircraft

open access: yesApplied Sciences, 2021
Aircraft winglets are well-established devices that improve aircraft fuel efficiency by enabling a higher lift over drag ratios and lower induced drag. Retrofitting winglets to existing aircraft also increases aircraft payload/range by the same order of ...

Definition and discussion of the intrinsic efficiency of winglets [PDF]

open access: yesINCAS Bulletin, 2018
Three simple equations are derived to define the “Intrinsic Aerodynamic Efficiency of Winglets” independent of the horizontal extension of the winglet and independent of the winglet’s (relative) height.
