摘要： An environmental sampling system (60) includes a passage (62) in an aircraft component and a removable collector (64) disposed in the passage (62). The passage (62) has an inlet (62a) at a first region (R1) and an outlet (62b) at a second region (R2). When the aircraft (21) component is in operation the first region (R1) is at a greater pressure than the second region (R2) such that air flows through the passage (62) from the inlet (62a) to the outlet (62b). The removable collector (64) is configured to retain constituents from the air and to react with the media designed to mimic corrosion effects seen at higher temperatures on engine parts. The constituents can then be characterized and correlated to engine deterioration (94) to predict maintenance activity.

摘要： Disclosed is an optical fiber overheat detection testing apparatus. The apparatus includes an optical fiber having a first end and a second end, the optical fiber having a predetermined length associated with a predetermined attenuation based on an overheat detection instrument loop. The apparatus includes a first fiber Bragg grating disposed on the optical fiber having a first wavelength spectrum based on a first temperature detection apparatus. The apparatus includes a second fiber Bragg grating disposed on the optical fiber having a second wavelength spectrum based on at least one of a plurality of overheat detection apparatuses.

摘要： The present disclosure provides a fastener (100). The fastener (100) includes an elongated body (102) having a first end (104) and a second end (106) opposite the first end (104). The fastener (100) also includes a head (108) having a first surface (110) and a second surface (112) opposite the first surface (110). The first end (104) of the elongated body (102) is coupled to the second surface (112) of the head (108), and a diameter (114) of the head (108) is greater than a diameter (116) of the elongated body (102). The fastener (100) also includes a sleeve (130) positioned over at least a portion of the elongated body (102) and the second surface (112) of the head (108). The fastener (100) also includes a plurality of textured elements (118) positioned on an exterior surface (119) of the sleeve (130) adjacent the second surface (112) of the head (108). One or more of the plurality of textured elements (118) extend from the exterior surface (119) of the sleeve (130) to the first surface (110) of the head (108). (Fig. 2C)
