Summary:To provide a leading edge high-lift device which can achieve both noise reduction and flight performance requirements, and a wing and an aircraft that are equipped with the device.SOLUTION: A leading edge high-lift device, which can be expanded and stored with respect to a main wing leading edge, comprises: a front edge part; a rear edge part which forms a clearance between itself and the main wing at the time of expansion; a cusp part which is formed on a lower edge of the front edge part; a lower surface part which is formed between the cusp part and the rear edge part; and a curved swollen part which is locally provided on a surface of the lower surface part, and protrudes to the main wing side in a cross-sectional shape perpendicular to a wing length direction of the main wing.SELECTED DRAWING: Figure 6 【課題】低騒音化と飛行性能への要求とを両立させることができる前縁高揚力装置、並びにこれを備えた翼および航空機を提供する。【解決手段】本発明の一形態に係る前縁高揚力装置は、母翼前縁に対して展開収納可能な前縁高揚力装置であって、前縁部と、展開時に前記母翼との間に隙間を形成する後縁部と、前記前縁部の下縁に形成されたカスプ部と、前記カスプ部と前記後縁部との間に形成された下面部と、前記下面部の表面に局所的に設けられ、前記母翼の翼長方向に垂直な断面形状において前記母翼側に凸なる湾曲形状の膨出部とを具備する。【選択図】図６
