PROBLEM TO BE SOLVED: To easily evaluate a water droplet desorption property for a wing surface of an aircraft.SOLUTION: A water droplet desorption test method for an aircraft comprises: providing a cylindrical member 2 simulating an air craft wing, having different water repellent properties separated by a boundary position 2b in a circumferential direction; blowing a wind to a surface of the cylindrical member 2 from a wind blowing direction D perpendicular to an axial direction of the cylindrical member 2 using a blower; supplying water droplets to a forward edge side part on the surface of the cylindrical member 2 with respect to a wind flow using a water supply cylinder 4; and photographing water droplets moving across the boundary position 2b on the surface of the cylindrical member 2 using a photographing camera.SELECTED DRAWING: Figure 2
【課題】航空機の翼表面の水滴離脱性を簡便に評価する。【解決手段】航空機の翼を模したものとして、境界位置2bを介して周方向で撥水性が異なる円筒部材2を用い、円筒部材2の表面に対し、当該円筒部材2の軸方向と直交する送風方向Dから送風機で風を送り、円筒部材2の表面のうち風の流れに対する前縁側部分に給水シリンダー4で水滴を供給し、風によって境界位置2bを跨いで円筒部材2の表面上を移動する水滴を撮影カメラで撮影する。【選択図】図2
