摘要： An atomizing injector includes a metering set having a swirl chamber, a spray orifice and one or more feed slots etched in a thin plate. The swirl chamber is etched in a first side of the plate and the spray orifice is etched through a second side to the center of the swirl chamber. Fuel feed slots extend non-radially to the swirl chamber. The injector also includes integral swirler structure. The swirler structure includes a cylindrical air swirler passage, also shaped by etching, through at least one other thin plate. The cylindrical air swirler passage is located in co-axial relation to the spray orifice of the plate of the fuel metering set such that fuel directed through the spray orifice passes through the air swirler passage and swirling air is imparted to the fuel such that the fuel has a swirling component of motion. At least one air feed slot is provided in fluid communication with the air swirler passage and extends in non-radial relation thereto. Air supply passages extend through the plates of the metering set and the swirler structure to feed the air feed slot in each plate of the swirler structure.

摘要： A multi-function spray nozzle for engine applications useful as a cooling device to introduce a fluid into the fluid stream of the engine, and as a cleaning device to introduce a fluid to clean internal components of the engine. The nozzle includes a multi-layered arrangement of etched plates defining flow paths for the first and second fluids. Non-radial feed slots direct the first fluid into a cylindrical swirl chamber. The swirling fluid exits the swirl chamber through a spray orifice or a prefilmer, depending on whether the nozzle is configured as a simplex or prefilmer nozzle. Other non-radial feed slots direct the second fluid inward, downstream of the first fluid, to create a fine dispersion of droplets for fluid stream cooling purposes. During cleaning, only the first fluid is introduced through the nozzle, which results in a larger droplet size suitable for cleaning purposes of the internal components of the engine.

摘要： An injector includes a plurality of flat, circular plates which provide fuel delivery and cooling of the injector. Fuel delivery passages in the plates have swirl chambers and spray orifices which are formed by chemical etching. A pair of fuel delivery plates define a fuel cavity therebetween, and include a plurality of radially-outwardly extending spokes, with the spokes from one fuel plate in adjacent, surface-to-surface relation with opposing spokes from the adjacent fuel plate. A fuel passage is defined between each of the opposing spokes, leading from the fuel cavity to a fuel outlet opening at the distal end of each spoke. A fuel tube delivers fuel to the fuel cavity between the plates, from where the fuel is then directed through the outlet openings. Downstream plates shape the fuel into appropriate sprays for ignition. An upstream cooling plate assembly directs air against the upstream fuel plate, and radially outwardly along the spokes of the upstream plate. The air is delivered through an air tube, concentric with the fuel delivery tube.

摘要： A fuel injector for a gas turbine engine of an aircraft has an inlet fitting, a fuel nozzle, and a housing stem with an internal conduit fluidly interconnecting the nozzle and fitting. The fuel nozzle includes a fuel swirler, which includes a plenum for receiving fuel from the conduit. A plurality of fuel passages direct fuel from the plenum to discharge orifices. The downstream ends of the passages are angled such that a swirl component is imparted to fuel exiting the discharge orifices. The swirling fuel is then applied to a prefilmer, which outwardly surrounds the fuel swirler. The passages in the fuel swirler are arranged such that the discharge orifices surround the entire nozzle for the even distribution of fuel. The plenum and passages are dimensioned and configured to receive and distribute the fuel for uniform spray patternization and low pressure drop, which provides improved combustion and flame stability.

摘要： A combustion system includes a combustion chamber and a fuel injection apparatus, where a radial inflow swirler stage in the injector housing includes a plurality of radial inflow swirlers spaced longitudinally from each other to direct air radially inward in a swirling motion to cause fuel streams to swirl and thoroughly mix with air before passing into the combustion chamber. A plurality of liquid fuel nozzles are supported in the housing in an annular arrangement to dispense liquid fuel in a plurality of sprays in the downstream direction. A plurality of gaseous fuel nozzles are also provided in the housing supported in an annular arrangement intermediate the liquid fuel nozzles. The plurality of gaseous fuel nozzles include a series of nozzles arranged in radial spokes between each of the liquid fuel nozzles, with the size of the openings in the gaseous fuel nozzles increasing in the radially outer direction from the longitudinal axis of the housing. An outer annular flow passage is provided around the nozzles to create a cylindrical sheet of air around all the fuel streams, while an annular flow passage is provided around each of the liquid fuel nozzles to provide an annular flow of air around each of the liquid fuel sprays. A central air passage provides air centrally of the arrangement of nozzles. The air vaporizes the liquid fuel as the fuel passes downstream through the housing.

摘要： A nozzle assembly (10) comprises a first-fuel-inlet tube (80), a second-fuel-inlet tube (90), and a plate stack (100). The nozzle-plate stack (100) defines a central circuit (104), corner air circuits (105), a first fuel circuit (106) and a second fuel circuit (107).

摘要： A force sensor utilizing force sensing element to generate an output signal that is commensurate with the force applied to the sensor. The force sensor includes a support element coupled to a resilient deflectable portion and at least one pivotable arm portion extending from the resilient deflectable portion; and a force sensing element supported by the base element and operably coupled to the at least one pivotable arm portion, wherein the force sensing element outputs an output signal that is proportional to a force applied to the at least one pivotable arm portion. The force sensor may be used a mass flow meter by coupling a fluid passage to the force sensor. The structure of the force sensor makes use of mechanical amplification to greatly increase the sensitivity of the sensor.
