APPARATUS AND METHOD FOR HEAT-SHEILDING FAN DUCT INNER WALL

摘要

A system and method for heat shielding an inner wall of a fan duct of an aircraft nacelle from engine heat. The system may include a heat shield and an insulation blanket. The heat shield may have a first layer of high temperature composite material bonded to a first surface of an insulant material and a second layer of high temperature composite material bonded to a second surface of the insulant material. The first layer of high temperature composite material may also be bonded to the inner wall. The insulation blanket may be positioned between the heat shield and the engine, and may be fastened to the heat shield and/or the inner wall.

1. A method of heat shielding an inner wall of a fan duct of an aircraft nacelle, the method comprising:
bonding a first layer of high temperature composite material to a first surface of an insulant material; bonding a second layer of high temperature composite material to a second surface of the insulant material, wherein the second surface is opposite the first surface, wherein the layers of high temperature composite material and the insulant material together form a heat shield; bonding the heat shield to the inner wall; and positioning an insulation blanket such that the heat shield is located between the inner wall and the insulation blanket, with the second layer of high temperature composite material located between the insulant material and the insulation blanket, wherein the insulation blanket comprises different material than the composite material.
