    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).

    Abstract: A machining system for electromachining a workpiece that in one embodiment includes a machine tool, a cutting tool for performing the eletromachining, and a tool holding apparatus for conductively holding the cutting tool and coupled to the machine tool. The tool holding apparatus includes a holding element for holding the cutting tool and at least one solution releasing element. The solution releasing element is used to receive machining solution and release the machining solution onto a predetermined area of the cutting tool through at least one group of channels. Each group of channels includes at least two channels configured to respectively release the machining solution onto at least two adjacent sections in the predetermined area of the cutting tool.
