AI Technical Summary

Technical Problem

Current aircraft designs often experience turbulent flow across significant portions of the wing, leading to reduced efficiency and increased drag, despite efforts to achieve laminar flow through various wing airfoil shapes.

Method used

The implementation of a slotted natural laminar flow airfoil with a two-element configuration, comprising a fore element and an aft element with a gap, promotes large areas of laminar flow and minimizes turbulent flow, enhancing lift and reducing drag by maintaining a favorable pressure gradient and utilizing hinged movement for additional lift and control.

Benefits of technology

The slotted airfoil design achieves reduced wing drag and improved lift characteristics, reducing undesired stall characteristics and enhancing overall aircraft efficiency and safety across various flight conditions.

Abstract

An aircraft capable of transonic flight is equipped with a slotted airfoil to significantly improve the cruise performance during flight. The aircraft includes a plurality of slotted airfoils uniquely configured to maximize natural laminar flow across the aircraft wings. In addition to reduced wing drag, the unique configuration minimizes shocks at various conditions over the course of a flight. Each slotted airfoil includes a fore element, an after element, and a slot disposed between the fore element and aft element. The aft element is maneuverable relative to the fore element. The slot is configured to promote a substantially constant air flow field onto the aft element during all flight angles of attack.
