A method of protecting a surface region of an aircraft against erosion by rain, airborne sand, hail and the like, includes starting with a sheet or sheets of a super-plastic alloy. The sheets of alloy are engaged with the surface region to be protected, and are then shaped, while at a temperature such that super-plastic properties of the alloy are exhibited, to follow the surface contours of the surface region to be protected. Thereafter the shaped sheet or sheets of alloy are secured in position on the surface region. The invention also resides in a surface region of an aircraft protected by a layer of superplastic alloy, and also in a protection member shaped to fit a particular aircraft surface region and formed from the superplastic alloy. |
