    Abstract: A method is provided for repairing a component of an item of rotational equipment, where the component includes a coating and a component body, and where the coating is on the component body and includes a defect. The method includes steps of: (a) removing a portion of the coating from the component body thereby forming a coating aperture, the removed portion of the coating including the defect, and the portion of the coating is removed such that the coating aperture has a coating aperture configuration which substantially matches a first patch configuration of a first coating patch; (b) preparing the component at the coating aperture to receive the first coating patch, (c) disposing the first coating patch within the coating aperture; and (d) attaching the first coating patch to the component body.

    Abstract: A non-destructive method for determining an amount of temperature exposure to a Bismaleimide Resin (BMI) matrix substrate, the method includes determining component data of a Bismaleimide Resin (BMI) matrix component via fourier transform infrared (FTIR) spectroscopy; correlating the component data to model data to determine a structural debit from temperature exposure; and bounding a structurally damaged area in response to the correlating.

    Abstract: A clamp for securing a component to an isogrid case of a gas turbine engine includes a top having an attachment feature for coupling the clamp to the component. The clamp further includes a bottom. The clamp further includes two sides extending from the top towards the bottom, each of the two sides being thicker at the bottom than at the top, and the two sides defining a shaped slot closer to the bottom than the top for receiving a rib of the isogrid case.

    Abstract: A method of sealing a first component to a second component comprising the steps of locating at least one fiber reinforced polyimide resin layer against a first sealing surface on a first component and against a second sealing surface on a second component. At least one fiber reinforced polyimide resin layer is compressed against the first sealing surface and the second sealing surface prior to curing at least one fiber reinforced polyimide resin layer. At least one fiber reinforced polyimide resin layer is heated to promote flow and conformation to the first sealing surface and the second sealing surface. At least one fiber reinforced polyimide resin layer is cured to provide a fluid tight seal between the first component and the second component.

    Abstract: A method of separating a lap joint assembly may include positioning a fluid emitter relative to a lap joint assembly. The lap joint assembly may include an adhesive lap joint between a first component and a second component. The method may further include emitting a cryogenic fluid stream from the fluid emitter at the adhesive lap joint. Positioning the fluid emitter and emitting the cryogenic fluid stream may include orienting the fluid emitter such that an angle between the cryogenic fluid stream and the adhesive lap joint is less than 45 degrees. The first component may be a sheath and the second component may be an airfoil body.
