Embodiment Construction

[0027] The various features of the disclosure will be presented as shown and described herein. Various embodiments may have the same or similar features and thus may be labeled with the same reference numerals, but preceded by a different first digit indicating that the features are shown. diagram. Thus, for example, an element "a" shown in Figure X could be labeled "Xa" and a similar feature in Figure Z could be labeled "Za". Although like reference numerals may be used in a general sense, as will be understood by those skilled in the art, various embodiments will be described and various features may include changes, alterations, modifications, etc., whether explicitly described or otherwise. All will be understood by those skilled in the art.

[0028] as in figure 1 As shown in , shown is a duct 100 for a gas turbine engine. The duct 100 may be a thrust reverser of a gas turbine engine mounted with a c-tube tower. Pipe 100 may have an internal fixation structure 102 an...

Abstract

A fire seal for use with a gas turbine engine is provided. The fire seal includes a body comprising a first metallic sheet and a second metallic sheet adjacent thereto, each sheet having a plurality of segmented fingers, the segmented fingers of the first metallic sheet and the second metallic sheet overlapped such that the space between fingers on one sheet does not overlap the space between the fingers on the other sheet, at least one finger of the first sheet having at least one first flow aperture therein and at least one finger of the second sheet having at least one second flow aperture, the flow aperture of one sheet overlapping the flow aperture of the other sheet. A mesh material is configured to cover the at least one flow aperture of the two sheets, wherein the mesh material is configured to allow the passage of air therethrough.

Description

technical field [0001] The subject matter disclosed herein relates generally to seals for use with gas turbine engines, and more particularly, to fire protection seals such as turkey feather seals. Background technique [0002] Regulatory requirements for modern aircraft require the containment of fires within the powerplant. For example, if there is a fire in the engine compartment surrounding a gas turbine engine, the structure defining the engine compartment must meet certain standards related to fire resistance. In order to meet the requirements related to fire resistance, fire protection seals are generally used between individual adjacent parts defining the engine compartment to seal between them and prevent the spread of fire. Fire seals are resistant to flames and fire environments and will contain fire by not allowing flames to pass through. [0003] One known fire seal arrangement is called a "turkey feather" fire seal. A turkey feather seal consists of two adja...
