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.

A wash spray apparatus for use with a gas turbine engine including an intake portion defined by an outer cowling, a central hub, and a plurality of spaced, radially extending struts interconnecting said hub and cowling, said wash spray apparatus comprising: a manifold assembly releasably secured to the cowling and including an array of spray nozzles disposed within said inlet, each nozzle being positioned upstream of said struts and disposed intermediate two adjacent struts, the spray flow path of each nozzle being generally aligned with the longitudinal axis of the engine, and with the tip of each nozzle including two parallel, flat projections such that the spray pattern of said nozzle is generally pyramidal including a generally elongated rectangular base, the longitudinal axis of which is generally perpendicular to the radial axis of the engine inlet, whereby the sprays from said nozzles provide an overlapping wash spray substantially along the entire length of the adjacent struts and the inside surface of the cowling.
