Abstract
An engine wash spray apparatus is releasably connected to the leading edge of a gas turbine engine for dispersing a cleaning, rinsing, or preservative fluid to the air intake area of the engine and on into the engine's internal air flow path. The apparatus includes a manifold having a plurality of nozzles of specific configuration and specific spaced relationship to achieve a uniform spray pattern, with each nozzle issuing an elongated spray, the longitudinal axis of which is generally perpendicular to a radius of the engine inlet, and with the nozzles being arranged within the engine inlet to achieve the overlapping wash spray. The cleaning fluid is dispersed within the air flow path of the engine while the engine is cranked, whereby the fluid is carried through the entire engine flow path for cleaning of the engine components.
