Title:
An ice coating prevention method of a wings structure
Document Type and Number:
Japanese Patent JP6151751
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a blade structure capable of appropriately preventing icing in an environment exposed to high-speed overcooling water droplets.SOLUTION: On a surface of an aircraft blade, a surface of a blade front edge portion predicted to be collided by high-speed overcooling water droplets at times of take-off and landing is formed as a non-water repellent region having a low surface roughness, and a super-water repellent paint is coated on the other surface regions. The non-water repellent region is heated by an electrothermal heater, whereby ice nuclei generated in the blade front edge portion are molten without being grown to icing, repelled by a water repellent structure of the blade surface subsequent to the blade front edge portion in a blade chord direction, and scattered and eliminated.SELECTED DRAWING: Figure 1
