PROBLEM TO BE SOLVED: To provide a flap in which noise due to wing tip vortex of the flap can be reduced.SOLUTION: A flap 3 of an aircraft comprises: a flap body 8 which is so provided as to be capable of being extended with respect to a main wing 2; a ramp 5 which is so provided as to be projected on a top face 301 at an end 40 of at least an outer broadside OTB in a span direction D2 of the flap body 8 and is inclined with respect to an axial direction D1 of the aircraft; and a projection 7 which smoothly projects from an underside 302 of the end 40 of at least the outer broadside. A rear end 52 of the ramp 5 is positioned on a side proximate to a side end edge 301A at the end 40 of the flap body 8 in the span direction D2 with respect to a virtual line which passes a front end 51 of the ramp 5 and is parallel to the axial direction D1.SELECTED DRAWING: Figure 4

    【課題】フラップの翼端渦に起因する騒音を低減することのできるフラップを提供する。【解決手段】航空機のフラップ3は、母翼2に対して展開可能に設けられるフラップ本体8と、フラップ本体8のスパン方向D2の少なくとも外舷側OTBの端部40における上面301に突設されていて、航空機の機軸方向D1に対して傾斜する傾斜部5と、少なくとも外舷側の端部40における下面302から滑らかに突出する突出部7とを備えている。傾斜部5の前端51を通り機軸方向D1と平行な仮想線よりも、傾斜部5の後端52が、フラップ本体8のスパン方向D2の端部40における側端縁301Aに近接する側に位置している。【選択図】図4
