AFT PYLON FAIRING FOR AIRCRAFT

摘要

Aft fairings (22) for aircraft pylons (14) are disclosed. In one example, a fairing (22) comprises: two opposite side panels (24) extending generally along a longitudinal direction of the fairing (22); a plurality of transverse ribs (28) interconnecting the two opposite side panels (24); and a heat shield (30) for exposure to a primary flow (16) of an aircraft engine (10). The heat shield (30) comprises transversely opposed side end portions (30A, 30C) and a mid portion (30B) disposed between the transversely opposed side end portions (30A, 30C). The heat shield (30) is secured to the ribs (28) via the mid portion (30B) of the heat shield (30). The transversely opposed side end portions (30A, 30C) are permitted to move outwardly from the mid portion (30B) due to thermal expansion of the heat shield (30).
