Estimating the term…
Provided herein are systems and methods for supplying a gas to one or more portions of an engine during an engine cleaning operation to limit the ingress of cleaning fluid. The systems and methods can also be used to supply the gas to the engine after a cleaning operation to remove residual cleaning fluid. In some embodiments, the methods include pressurizing a bleed system to limit ingress of cleaning fluid or dry the bleed system. The methods may use a portion of a reverse bleed apparatus associated with the bleed system to supply the gas to the bleed system. In addition, an external gas supply system may be coupled to a bleed duct to supply the gas. In some embodiments, the methods include pressurizing a sump system of the gas turbine engine to limit ingress of cleaning fluid into the sump system during the cleaning operation.
A method for cleaning an engine core of a gas turbine engine, the method comprising:
A method for cleaning an engine core of a gas turbine engine, the gas turbine engine comprising at least one of a bleed system in fluid communication with the engine core or a sump system in fluid communication with the engine core, the gas turbine engine defining an access port within the engine core, the method comprising:
