Removable wash spray apparatus for gas turbine engine

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.

Fluid jet cutting system

Abstract: Apparatus and method are disclosed utilizing a high strength fluid jet in an operative cutting system. A computer driven carriage and nozzle movable on the carriage effectuate cutting in the X-Y direction and a sensor arrangement is used to position the nozzle in the Z-direction. The workpiece rests on a flexible wire bed which supports the workpiece and at the same time allows a fluid catcher to pass under the workpiece in registration with the nozzle. A support channeled for allow for movement of the fluid catcher provides support for the workpiece in the area of the cut.

Two stage (premixed/diffusion) gas only secondary fuel nozzle

Abstract: A secondary nozzle for a gas turbine includes an elongated, tubular nozzle body having an inlet end and an outlet end; a tubular core assembly having an outer diameter less than an interior diameter of the tubular nozzle body to thereby define a diffusion fuel passage between the core assembly and the tubular nozzle body extending to the outlet end, and a premix fuel passage through the core assembly extending to a pilot orifice at the outlet end; an air passage located along at least a portion of the tubular nozzle body and located radially between the diffusion and premix fuel passages; and, a plurality of gas injectors extending radially out of the elongated tubular nozzle body from the premix fuel passage.

Method and device for paste coating

Abstract: PROBLEM TO BE SOLVED: To facilitate the rapid adjustment of the coating quantity of paste to form a paste pattern having a desired shape with high precision SOLUTION: While changing the relative position relation of a nozzle 13a and an actual substrate 22, by discharging paste 23 from a discharge port of the nozzle 13a, a desired paste pattern is formed on the surface of an actual substrate 22 In this case, when the nozzle 13a reaches a position on the actual substrate 22 determined as a change point in advance, the distance for the surface of the actual substrate 22 to the paste discharge port of the nozzle 13a, that is, the coating height is changed from a coating height 1 to a coating height 2 set in advance, and accordingly, paste discharge from the nozzle 13a is changed In this way, coating paste thickness can be changed more quickly than changing of pressure applied to a paste housing cylinder provided with the nozzle 13a
