摘要： The present disclosure is directed to a method 200 for in-situ cleaning one or more components of a gas turbine engine (10) using an abrasive gel detergent (84). More specifically, the gel detergent (84) includes a plurality of abrasive particles suspended in a gel composition. Further, the abrasive particles include organic material. Moreover, the gel composition is formed of a mixture of detergent particles dissolved in a gel reactant. Thus, the method includes injecting 202 the gel detergent (84) into at least a portion of the gas turbine engine (10) at a predetermined pressure. In addition, the method includes allowing 204 the gel detergent (84) to flow across or within one or more of the components of the gas turbine engine (10) so as to clean one or more of the components.

摘要： The present disclosure is directed to a method and detergent for in-situ (e.g. on-wing) cleaning one or more components of a gas turbine engine (10). The method includes injecting a dry detergent (84) into the gas turbine engine (10). Further, the dry detergent (84) 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 (84) through at least a portion of the gas turbine engine (10) so as to clean the one or more components thereof.

摘要： An atomizing spray nozzle device 100 includes plural inlets that receive different phases of materials of a coating. The device 100 also includes an atomizing zone housing 522 portion fluidly coupled with the inlets 518, 520 and shaped to mix the different phases of the materials into a mixed phase slurry. The device 100 also includes a plenum housing portion 524 fluidly coupled with the atomizing housing portion 522 along the center axis of the device 100. The plenum housing portion 524 includes an interior plenum 546 that is elongated along the center axis 106 of the device 100. The plenum 546 is configured to receive the mixed phase slurry from the atomizing zone. The device 100 also includes one or more delivery nozzles 526, 528, 530 fluidly coupled with the plenum 546. The one or more delivery nozzles 526, 528, 530 provide one or more outlets from which the mixed phase slurry is delivered onto one or more surfaces of a target object as a coating on the target object.
