    Abstract: A fan platform for electrically grounding an airfoil of a gas turbine engine includes a flow path surface extending between a first and second side. An inner surface radially opposing the flow path surface also extends between the first and second side, and includes a body portion extending radially inwardly therefrom. At least a first conductive path for grounding travels from the first side via the body portion.

    Abstract: A fan rotor includes a rotor body with at least one slot receiving a fan blade. The fan blade has an outer surface, at least at some areas, formed of a first material and an airfoil extending from a dovetail. The dovetail is received in the slot. A spacer is positioned radially inwardly of the dovetail biasing the fan blade against the slot. The spacer includes a grounding element, which is in contact with a portion of the dovetail formed of a second material that is more electrically conductive than the first material. The grounding element is in contact with a rotating element that rotates with the rotor. The rotating element is formed of a third material. The first material is less electrically conductive than the third material. The grounding and rotating elements form a ground path from the portion of the dovetail into the rotor.

    Abstract: A method of joining a microwave transparent component 36 to a host component 34 or 18 includes the steps of applying a Titanium-Tungsten (TiW) coating 44 to the microwave transparent component, applying a metal layer 46 over the TiW coating and brazing the microwave transparent component to the host. In a more detailed embodiment, the microwave transparent component is a ceramic component and the host component is a nonceramic component. In an even more detailed embodiment, the nonceramic component is made of a nickel base alloy and the metal layer is a nickel plating. A turbine engine component comprising a microwave nontransparent host 34 or 18 and a microwave transparent window 36 brazed to the host is also described.

    Abstract: The invention relates to an axial-flow thermal turbomachine having a metallic rotor (1), in which rotor blades (3) made of an intermetallic compound are mounted in a circumferential groove to form a row of blades. The invention is characterized in that at least two rotor blades (3′) which are at a uniform distance from one another and are made of a more ductile material are arranged in the said row of blades between the intermetallic rotor blades (3), the rotor blades (3′) made of the more ductile material either being considerably longer than the intermetallic blades (3) or, if they are of the same length, having a different blade tip shape than the intermetallic blades (3).
