<p>An insulation blanket (20) is disclosed that contains fire-blocking material s for preventing rapid penetration of fire into an aircraft fuselage (28) in case of fire outside the aircraft. The insulation blanket (20) contains at least one layer (24) of fiberglass or other thermal-acoustic insulation material without fire-blocking properties, and one or more layers (33) of fire-blocking material. The fire blocking material (33) is wider than the thermal-acoustic insulatio n (24) so that it may be folded against and attached to adjacent structural frame members (31) of the fuselage. In the alternative, a thermal-acoustic insulation material (24) is used that has fire-blocking properties instead of the separate layers of fire-blocking and thermal-acoustic insulation materials. A method for installing insulation blankets according to the present invention is disclosed, whereby a fire-blocking insulation portion of the blanket is folded against and attached to frame members (31) of the aircraft using attachment posts or spring clips.</p> |
