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: An air-oil cooler (AOC) for a gas turbine engine is disclosed. The AOC may comprise an oil inlet, an oil outlet, and heat exchange elements between the oil inlet and the oil outlet. The AOC may be longitudinally positioned between a fan and a V-groove of the engine and radially spaced between a low pressure compressor and a low pressure compressor panel. A gas turbine engine comprising an AOC is disclosed. The AOC of the engine may comprise an oil inlet, an oil outlet, and heat exchange elements between the oil inlet and the oil outlet. The AOC of the engine may be longitudinally positioned between a fan and a V-groove of the engine and radially spaced between a low pressure compressor and a low pressure compressor panel. A method of operating an AOC for use on a gas turbine engine is also disclosed.

Abstract: A fan blade containment assembly includes a flow surface forward of the fan blades that is defined by the inner surface of the case. Various construction details are developed that provide an axially and circumferentially continuous flow surface forward of the fan blades. The continuity and uniformity eliminates structural discontinuities that increase noise levels associated with the engine. In a particular embodiment, the case is formed from an isogrid structure, a plurality of cloth wraps wound under tension around the case, and a plurality of acoustic panels downstream of the fan blades. The flow surface forward of the fan blades is provided by machining the inner surface of the case to the desired shape.
Abstract translation: 风扇叶片容纳组件包括由壳体的内表面限定的风扇叶片的前方的流动面。 开发了各种构造细节，其提供了风扇叶片前方的轴向和周向连续的流动表面。 连续性和均匀性消除了增加与发动机相关联的噪音水平的结构不连续性。 在一个具体实施例中，壳体由等离子体结构，围绕壳体的张力缠绕的多个布料包裹，以及在风扇叶片下游的多个隔音板形成。 通过将壳体的内表面加工成所需的形状来提供风扇叶片前方的流动面。
