ABSTRACT:
A wash apparatus includes a harness assembly comprising a coupling device a coupling device for connecting one or more fluid supply lines to one or more fluid delivery lines; one or more fluid delivery lines removably attached at one end to the coupling device's first portion and positioned for delivering washing fluid directly into the gas turbine engine core as the engine is cranked; one or more fluid supply lines removably attached to the coupling device's second portion for supplying washing fluid to the harness assembly and remaining in a static position relative to the rotating fluid delivery lines; one or more harness rings attached to the one or more fluid delivery lines for spacing, stabilizing, and positioning the fluid delivery lines relative to the fan blades; and a connector for removably attaching the harness assembly directly onto the fan hub.
