Abstract

Turbine engines, and particularly gas or combustion turbine engines, are rotary engines that extract energy from a flow of pressurized combusted gases passing through the engine onto a multitude of rotating turbine blades. Air flows passing through the engine may contain particles such as dust, and it can be beneficial to remove these particles before they encounter airfoils within the engine. Dust collectors can utilize centrifugal forces to remove particles from rotating airflows and purify the air for use in other applications.

CYCLONE DUST COLLECTOR

BACKGROUND OF THE INVENTION

[0001] Turbine engines, and particularly gas or combustion turbine engines, are rotary

engines that extract energy from a flow of pressurized combusted gases passing through

the engine onto a multitude of rotating turbine blades.

[0002] Air flows passing through the engine may contain particles such as dust, and it

can be beneficial to remove these particles before they encounter airfoils within the

engine. Dust collectors can utilize centrifugal forces to remove particles from rotating

airflows and purify the air for use in other applications.

[0006] FIG. 3 illustrates airflows through the dust collector of FIG. 2.

[0007] FIG. 4 is a schematic diagram of the dust collector of FIG. 2 in a first

configuration.

[0008] FIG. 5 is a schematic diagram of the dust collector of FIG. 2 in a second

configuration.

DESCRIPTION OF EMBODIMENTS OF THE INVENTION

[0010] The described embodiments of the present disclosure are directed to a dust

collector for a turbine engine. For purposes of illustration, the present disclosure will be

described with respect to the turbine for an aircraft turbine engine. It will be understood,

however, that the disclosure is not so limited and may have general applicability within

an engine, including compressors, as well as in non-aircraft applications, such as other

mobile applications and non-mobile industrial or commercial applications, including

power plants, or residential applications such as home appliances.

[0011] As used herein, the term “forward” or “upstream” refers to moving in a direction

toward the engine inlet, or a component being relatively closer to the engine inlet as

compared to another component. The term “aft” or “downstream” used in conjunction

with “forward” or “upstream” refers to a direction toward the rear or outlet of the engine

or being relatively closer to the engine outlet as compared to another component.

[0012] Additionally, as used herein, the terms “radial” or “radially” refer to a

dimension extending between a center longitudinal axis of the engine and an outer engine

circumference, and “a set” as used herein can include any number including only one.

[0013] All directional references (e.g., radial, axial, proximal, distal, upper, lower,

upward, downward, left, right, lateral, front, back, top, bottom, above, below, vertical,

horizontal, clockwise, counterclockwise, upstream, downstream, forward, aft, etc.) are

only used for identification purposes to aid the reader’s understanding of the present

disclosure, and do not create limitations, particularly as to the positi...
