To provide a technique concerning a leading edge high-lift device which can reduce noises generated from an inboard end of slat and a slat support mechanism.SOLUTION: A leading edge high-lift device, which can be expanded and stored with respect to a main wing leading edge of an airframe, comprises a slat body, and a cushioning part. The slat body has: a front edge part; a rear edge part which forms a clearance between itself and a main wing during expansion; a cusp part formed on a lower edge of the front edge part; a cob part formed between the cusp part the rear edge part; and an inboard end face which is formed between the front edge part and the cob part, and is positioned on a shell side of the airframe. The cushioning part is provided at an inboard end part of the slat body that includes the inboard end face and an inboard side surface of the cob part, and reduces pressure fluctuation in air stream on the inboard end face or the inboard side surface of the cob part.SELECTED DRAWING: Figure 12 【課題】スラット内舷端部やスラット支持機構から発生する騒音を低減させることができる前縁高揚力装置に関する技術を提供する。【解決手段】本発明の一形態に係る前縁高揚力装置は、機体の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、スラット本体と、緩衝部とを具備する。前記スラット本体は、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コブ部と、前記前縁部と前記コブ部との間に形成され前記機体の胴体側に位置する内舷端面と、を有する。前記緩衝部は、前記内舷端面および前記コブ部の内舷側表面を含む前記スラット本体の内舷端部に設けられ、前記内舷端面または前記コブ部の内舷側表面における気流の圧力変動を低減する。【選択図】図１２
