Leading-edge high-lift device, wing, aircraft, and buffering member

Abstract

A leading-edge high-lift device according to an embodiment of the present invention is a leading-edge high-lift device that is deployable and retractable from/into a fixed leading edge of a main wing of an aircraft and includes a slat main body and a buffering portion. The slat main body includes a leading edge portion, a trailing edge portion that forms a gap between a trailing edge portion and the main wing during deployment, a cusp portion formed at a lower edge of the leading edge portion, a cove portion formed between the cusp portion and the trailing edge portion, and an inboard end surface that is formed between the leading edge portion and the cove portion and is positioned on a fuselage side of the aircraft. The buffering portion is provided at an inboard end portion of the slat main body including the inboard end surface and an inboard-side surface of the cove portion and reduces pressure fluctuations in airflow on the inboard end surface or the inboard-side surface of the cove portion.
