Appl. No.:

09/532534

Inventors:

Erlendur Steinthorsson - Westlake OH
Michael A. Benjamin - Shaker Heights OH

Assignee:

Parker-Hannifin Corporation - Cleveland OH

International Classification:

F23R 328

US Classification:

60776, 60748

Abstract:

A fuel nozzle for dispensing an atomized fluid spray into the combustion chamber of a gas turbine engine. The nozzle includes a body assembly with an inner fuel passage and an annular outer atomizing air passage. The inner fuel passage extends axially along a longitudinal axis to a first terminal end defining a first discharge orifice of the nozzle. The outer air passage extends coaxially with the inner fuel passage along the longitudinal axis to a second terminal end disposed concentrically with the first terminal end and defining a second discharge orifice oriented such that the discharge therefrom impinges on the fuel discharge from the first discharge orifice. An array of turning vanes is disposed within the outer air passage in a circular locus about the longitudinal axis. Each of the vanes is configured generally in the shape of an airfoil and has a pressure side and an opposing suction side. The vanes extend axially from a leading edge surface to a tapering trailing edge surface along a corresponding array of chordal axes, each of axes is disposed at a given turning angle to the longitudinal axis.

International Classification:

US Classification:

239404, 239405, 239422, 239423, 239428

Abstract:

A hybrid atomizing fuel nozzle includes a stem with primary and secondary fuel circuits. A nozzle assembly fixed at the downstream end of the stem includes primary and secondary nozzle portions. A shroud and swirler assembly surrounds the nozzle assembly, and includes an annular body with a prefilmer surface. A radial inflow swirler in the annular body directs a first swirling air flow radially inward toward the secondary nozzle portion. An outer air swirler disposed in surrounding relation to the annular body provides a converging second swirling air flow downstream of the prefilmer surface. Discrete fuel passages direct fuel streams outward and downstream toward and against the prefilmer surface. The fuel passes through the first air flow and is evenly distributed across the prefilmer surface in a thin continuous sheet. The first and second air flows then cause the sheet to form a conical spray of atomized fuel.

International Classification:

F02C 100

US Classification:

60740, 60748, 239403, 239405

Abstract:

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.

International Classification:

US Classification:

60740, 60742, 60 3983, 60746

Abstract:

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 nozzle includes a body assembly with an inner fuel passage and an annular outer atomizing air passage. An array of turning vanes is disposed within the outer fuel passage. Each of the vanes is configured generally in the shape of an airfoil in having a pressure side and an opposing suction side, the suction side of each vane being spaced-apart from a juxtaposing pressure side of an adjacent vane to define a corresponding one of a plurality of aligned air flow channels therebetween. Fuel is directed through the fuel flow channels to be issued from the nozzle as a generally helical flow having a substantial uniform velocity profile.

Each manifold segment includes a plurality of nozzles arranged in a linear, planar array; with each nozzle including a fuel distribution assembly and an air swirler assembly. The manifold segments are supported at angles to one another, such that that the sprays from one array of nozzles in one segment are provided in a different direction than the sprays from another array of nozzles in an adjacent manifold segment.

Abstract:

The adjustable louvered armor window system invention comprises angled louvers made of the lightweight opaque armor. For the front window a viewing window of ballistic glass can be installed, the rear or sides could be solid armor. The louvers have overlaps to provide for gap protection. When no threat is present, the louvers are in the full open position. Once a threat is detected, then the louvers are closed. The movement of the louvers can be accomplished by a push/pull cable, hydraulic pressure, air pressure or other means. The system in the fully open position allows for a complete unobstructed viewing area. In the semi-deployed or partial down position, the system provides partial ballistic coverage for the occupant, and still allows for some occupant vision capability. In the fully deployed, or fully closed position, the system provides full ballistic coverage for the occupant, with a small viewing area or port, which is made of ballistic grade transparent armor.
