Abstract: A method for cleaning components of a gas turbine engine is presented. The method includes introducing a working fluid into a gas flow path or a cooling circuit defined by the one or more components of the gas turbine engine such that the working fluid impinges upon a surface of the one or more components of the gas turbine engine, wherein the working fluid includes a plurality of detergent droplets entrained in a flow of steam. A system for cleaning components of a gas turbine engine are also presented.

Abstract: The present disclosure is directed to a method for in-situ cleaning one or more components of a gas turbine engine using an abrasive gel detergent. More specifically, the gel detergent 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 the gel detergent into at least a portion of the gas turbine engine at a predetermined pressure. In addition, the method includes allowing the gel detergent to flow across or within one or more of the components of the gas turbine engine so as to clean one or more of the components.

Abstract: A system and method for cleaning an installed gas turbine engine is provided. The system may include a controller on an engine core, wherein the engine core defines a primary gas path and includes at least one airfoil extending into the primary gas path. The method may include initiating a cleaning program and directing a cleaning fluid toward the engine core in response to the initiation of the cleaning program. The method may further include initiating delivery of the cleaning fluid as a non-vaporized liquid within the primary gas path to the engine core.

Abstract: A wash system for a gas turbine engine includes a foam generating device configured for receiving and aerating a flow of wash fluid to generate a flow of foamed wash fluid having particular foam characteristics. The flow of foamed wash fluid passes through a distribution manifold where it is selectively directed through a plurality of wash lines to desired portions of the gas turbine engine. The wash system further includes a controller configured for manipulating the foam characteristics of the flow of foamed wash fluid and using the distribution manifold to selectively direct the flow of foamed wash fluid to desired portions of the gas turbine engine for optimal cleaning and improved engine efficiency.

Abstract: One example aspect of the present disclosure is directed to a method for enhancing a maintenance operation routine. The method includes receiving, at one or more processors, engine history data. The method includes comparing, at the one or more processors, the received engine history data to expected engine history data. The method includes determining, at the one or more processors, an expected effectiveness of a plurality of maintenance operation types based on the comparison. The method includes selecting, at the one or more processors, one of the plurality of maintenance operation types based on the determinations. The method includes transmitting, at the one or more processors, a signal indicative of a notification of the selected maintenance operation type.
