20090084895 | Aircraft Skid Shoes with Wear-Resistant Cladding Layers - Aircraft skid shoes are provided with wear-resistant cladding layers. Powders of hard particles and braze material are impregnated into at least one cloth which is applied to the wear surface of a skid shoe of a helicopter or other aircraft. The skid shoe and cloth are heated to a brazing temperature to metallurgically bond the hard particles together and to the skid shoe substrate. The resultant cladding layers provide significantly increased abrasion resistance and reduced unit weight in comparison with skid shoes having conventional wear-resistant materials. | 04-02-2009 |
