Title:
WING AND AIRCRAFT
Document Type and Number:
WIPO Patent Application WO/2017/217015
Kind Code:
A1
Abstract:
[Problem] To provide a wing able to achieve a reduction in friction drag and easy to design and manufacture and an aircraft having such a wing. [Solution] This wing 1 is typically used as the main wing of an aircraft 100. This wing 1 is a sweepback wing having a sweepback angle A. The wing 1 is configured such that the surface pressure (pressure distribution (Cp)) over the top surface of the front edge 11 vicinity in the fluid increases towards the wing tip 15 from the wing root 17. The cross-flow component of the outer streamline on the wing 1 surface is small in the front edge 11 vicinity, and boundary layer transition is not easily induced in the front edge 11 vicinity. Thus, it is possible to reduce friction drag caused by cross-flow instability.
