Abstract: Embodiments in accordance with the present disclosure include a meta-stable detergent based foam generating device of a turbine cleaning system includes a manifold configured to receive a liquid detergent and an expansion gas, a gas supply source configured to store the expansion gas, and one or more aerators fluidly coupled with, and between, the gas supply source and the manifold. Each aerator of the one or more aerators comprises an orifice through which the expansion gas enters the manifold, and wherein the orifice of each aerator is sized to enable generation of a meta-stable detergent based foam having bubbles with bubble diameters within a range of 10 microns (3.9×10−4 inches inches) and 5 millimeters (0.2 inches), having a half-life within a range of 5 minutes and 180 minutes, or a combination thereof.

Abstract: The present disclosure provides methods and systems for in situ cleaning of hot gas flowpath components of a turbine engine that form portions of a hot gas flowpath extending through the turbine. The hot gas flowpath components may include a layer of accumulated contaminants on first portions thereof that form a respective portion of the hot gas flowpath. The first portions may include a thermal battier coating (TBC), and the layer of accumulated contaminants may overlie the TBC and at least partially infiltrate into the TBC. The accumulated contaminants may include CaO—MgO—Al2O3-SiO2 (CMAS) partial melt. The methods may include introducing an acid-including detergent into the hot gas flowpath of the turbine engine and onto the hot gas flowpath components to clean the accumulated contaminants from the first surfaces of the components.

Abstract: Systems and methods for removing heat are provided. For example, a system comprises a support apparatus and a cooling apparatus, including a suction device for forcing air through a gas turbine engine, disposed on the support apparatus, which is moveable with respect to the engine to position the cooling apparatus in contact with an engine exhaust. A nozzle in operative communication with the suction device may force air through the engine. Further, the support apparatus may comprise a lift device, an angle adjustment mechanism, and a nozzle support element disposed on a longitudinal slide rail for adjusting a height, an angle, and a longitudinal position of the nozzle. A method of removing heat from a gas turbine engine after shutdown comprises positioning a cooling apparatus adjacent an exhaust; sealing the cooling apparatus to the exhaust; and operating a suction device of the cooling apparatus to move air through the engine.

Abstract: The present disclosure is directed to a method for in-situ (e.g. on-wing) cleaning one or more components of a gas turbine engine. The method includes injecting a dry detergent into the gas turbine engine. Further, the dry detergent contains a plurality of detergent particles having varying particle sizes. More specifically, the plurality of detergent particles includes a first set of particles having a median particle diameter within a first micron range and a second set of particles having a median particle diameter within a second micron range. Further, a median of the second micron range is larger than a median of the first micron range. In addition, the method includes circulating the dry detergent through at least a portion of the gas turbine engine so as to clean the one or more components thereof.
