METHOD AND DEVICE FOR TESTING WATER DROPLET SHEDDING ABILITY OF AIRCRAFT WING
First Claim
1. A method for testing water droplet shedding ability of a surface of an aircraft wing, the method comprising:
- blowing air toward a surface of a cylindrical member in an airflow direction perpendicular to an axial direction of the cylindrical member, the cylindrical member simulating the wing and having water-related surface characteristics that differ across a predetermined boundary position in a circumferential direction;
supplying a water droplet to a portion of the surface of the cylindrical member on a leading edge side with respect to a flow of the air; and
capturing an image of the water droplet that moves on the surface of the cylindrical member across the boundary position due to the flow of the air.
