Abstract: A digital inspection assistant and a system and a method of using the inspection assistant as an aid during a visual inspection of a gas turbine engine are provided. In one aspect, the inspection assistant receives data that includes images captured by an optical probe installed through an access port of a gas turbine engine. The images can be still images or video of the interior of a core of the engine. A gateway can route the data to the inspection assistant. The inspection assistant can provide interactive inspection guidance to an operator and can detect component defects. The inspection assistant can provide real time defect analysis to the operator by generating an alert upon detection of a defect. The generated alert can be audible, a visual graphic presented on a display of the visual inspection, and/or some other suitable alert. The analysis results can assist the operator during inspection.

Abstract: A wastewater collection system of a water wash system includes a collection duct configured to attach to a gas turbine engine for receiving a mixture of air and wash liquid from the gas turbine engine during washing. The wastewater collection system additionally includes a separation assembly, the separation assembly including a shaft, one or more impellers mounted to the shaft, and a casing. The casing at least partially encloses the shaft and encloses the one or more impellers. The casing defines an inlet for fluidly connecting with the collection duct, an air outlet, and a liquid outlet. The air outlet is disposed opposite the one or more impellers from the inlet and the liquid outlet.

Abstract: A water wash system (200) for a gas turbine engine (100) having a fan (126) and a front hub (136), the front hub (136) can be rotated with the fan (126). The water wash system (200) generally includes a head unit (202) and a base assembly (204). The head unit (202) includes a mounting structure (206) and one or more wash fluid lines (208) for spraying a wash fluid into the gas turbine engine (100). The mounting structure (206) defines an inner friction surface (252) for contacting the front hub (136) of the gas turbine engine (100). Additionally, the base assembly (204) is operatively connected to the head unit (202) and is configured to press the head unit (202) towards the front hub (136) to fix the inner friction surface (252) against the front hub (136).
