Embodiment Construction

[0027] The descriptors "first", "second", "third", etc. are used herein when identifying a plurality of elements or components that may be referred to separately. Unless otherwise stated or understood based on the context in which they are used, such descriptors are not intended to confer any sense of priority, physical order or arrangement in the list, or chronological order, but rather the disclosed examples are used only for ease of understanding, respectively A label that refers to multiple elements or parts. In some examples, the descriptor "first" may be used to refer to an element in the detailed description, while a different descriptor such as "second" or "third" may be used in the claims to refer to the same element. In such cases, it should be understood that such descriptors are used only for ease of reference to multiple elements or components.

[0028] As used herein, the terms "upstream" and "downstream" refer to relative directions with respect to fluid flow i...

Abstract

Methods, apparatus, systems, and articles of manufacture are to control air flow separation of an engine. An example turbofan includes a nacelle having an outer lip surface, an inner lip surface, a first opening and a second opening, the first opening coupled to a first region forward of a fan of the turbofan, the second opening coupled to a second region aft of the fan, the nacelle including a first pressure sensor coupled to the outer lip surface, a second pressure sensor coupled to the inner lip surface, and an actuator, and a conduit coupled to the actuator, the conduit configured to have a first end and a second end, the first end coupled to the first opening, the second end coupled to the second opening.

Description

technical field [0001] The present disclosure relates generally to gas turbine engines, and more particularly to methods and apparatus for controlling gas flow separation of the engines. Background technique [0002] A gas turbine engine typically includes an inlet section, a compressor section, a combustion section, a turbine section and an exhaust section in a serial flow order. In operation, air enters the inlet section and flows to the compressor section where one or more axial compressors gradually compress the air until it reaches the combustion section. Fuel is mixed with compressed air and burned in the combustion section, producing combustion gases. Combustion gases flow from the combustion section through a hot gas path defined within the turbine section and then exit the turbine section via the exhaust section. [0003] In a particular configuration, the compressor section includes a low pressure compressor ("LP compressor") and a high pressure compressor ("HP c...
