摘要:
An airfoil for a gas turbine engine comprising a root, a tip, and leading and trailing edges extending between the root and the tip. The airfoil has a non-metallic core which is composed of a composite material, and a metallic coating disposed on at least a portion of the composite core, such as along the leading edge of the airfoil for example. The metallic coating is composed of a nanocrystalline metal, and forms an outer surface of the portion of the airfoil onto which the coating is applied.

摘要:
A method of applying a nanocrystalline coating to a gas turbine engine component is described. The method comprises the steps of applying an intermediate bond coat to at least a portion of the component, and then applying the nanocrystalline coating to at least the portion of the component overtop of the intermediate bond coat. The component may include, for example, a blade of which a dovetail portion of the blade root is protected by applying the intermediate bond coat and the nanocrystalline coating thereto.

A cassette for use in delivering a continuous length of filament. The cassette includes a housing having a first aperture and a spool rotatably mountable in the cassette housing. The spool contains a first female receptacle alignable with the first aperture, and a flexible boot is attached to the cassette housing and aligned with the first aperture. A removable plug is insertable through the first aperture and into the flexible boot for receipt within the first female receptacle of the spool to prevent rotation of the spool within the cassette housing.

The present invention is directed to systems and methods for trailer alignment including a clamping mechanism configured to rigidly and removably clamp to a neck of a trailer hitch ball. An arm arrangement is rotatably attached to the clamping mechanism. The arm arrangement configured to extend from the clamp arrangement to beyond an edge of a tow vehicle. A mirror may be attached to the arm arrangement and configured to provide a view of the trailer hitch ball from the inside of the tow vehicle. A sight rod may be attached to the clamping device and configured to bend in response to a trailer coupler approaching the trailer hitch ball at a predetermined distance from a selectable angle. The clamping mechanism may include a pair of opposed jaws configured to adjustably clamp between a range of about 0.8 and about 1.5 inches.
