International Classification:

F02C 7/18
F02C 7/28
F01D 21/00
F01D 9/02

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.

B64F 5/40
G07C 5/08

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.

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.
