Abstract
Provided is a wing structure comprising a wing body formed from fiber-reinforced plastic (FRP), and an erosion suppression layer provided so as to cover at least a portion of a front edge of the wing structure. The erosion suppression layer contains a thermal spraying layer configured so as to maintain, by having a prescribed surface roughness, a liquid film formed on the erosion suppression layer.
Claims9
A wing structure comprising:
- a wing body formed of an FRP;
- and
- an erosion suppression layer provided to cover at least a part of a leading edge of the wing body,
- wherein the erosion suppression layer includes a thermal spray layer configured to maintain a liquid film formed on the erosion suppression layer by having a predetermined surface roughness.

A wing structure manufacturing method comprising:
- a step of preparing a wing body formed of an FRP;
- a thermal spray layer forming step of providing a thermal spray layer by thermal spraying so as to cover at least a part of a leading edge of the wing body;
- and
- a surface treatment step of performing a surface treatment of the thermal spray layer such that a surface of the thermal spray layer satisfies a condition of a root mean square height Rq=5 to 40 μm after the thermal spray layer forming step.
