Abstract

Methods and apparatus for forming and installing insulation blankets in a vehicle compartment are disclosed. An example apparatus includes an insulation blanket that includes an outer layer, an insulation layer disposed in the outer layer, and a first fastener disposed in the insulation layer. The outer layer and the insulation layer are to form to a first channel. The first fastener is to receive, via the first channel, a first portion of a vehicle compartment frame to sealingly couple the insulation layer and the outer layer of the insulation blanket to the vehicle compartment frame.

Claims

1. An apparatus comprising:

an insulation blanket including;

an outer layer;

an insulation layer disposed in the outer layer; and

a first fastener disposed in the insulation layer, the outer layer and the insulation layer to form to a first channel, the first fastener to receive, via the first channel, a first portion of a vehicle compartment frame to sealingly couple the insulation layer and the outer layer of the insulation blanket to the vehicle compartment frame.

2. The apparatus of claim 1, wherein the vehicle compartment frame is an aircraft compartment frame disposed in a nacelle of an aircraft, the insulation blanket to couple to the aircraft compartment frame to insulate an aircraft compartment to deter fluid from flowing between the aircraft compartment and an exterior of the aircraft.

3. The apparatus of claim 1, wherein the first fastener is disposed in the insulation blanket to prevent the first fastener from separating from the insulation blanket.

4. The apparatus of claim 1, wherein the insulation blanket further includes:

a bay blanket formed by the outer layer and the insulation layer; and

a cap strip extending along and coupled to a first side of the bay blanket, the cap strip formed by the outer layer and the insulation layer and including the first fastener, the cap strip to sealingly couple the insulation blanket to the first portion of the vehicle compartment frame.

5. The apparatus of claim 4, further including a flexible cover film extending from a second side of the bay blanket opposite the cap strip, the cover film to engage a second portion of the vehicle compartment frame spaced apart from the first portion of the vehicle compartment frame, the cover film to be coupled to the second portion of the vehicle compartment frame via a second insulation blanket.

6. The apparatus of claim 1, further including a second fastener disposed in the insulation layer, the second fastener and the first fastener extending along a first side of the insulation blanket, the second fastener spaced apart from the first fastener, the second fastener to receive, via a second channel formed by the outer layer and the insulation layer, the first portion of the vehicle compartment frame.

7. The apparatus of claim 1, wherein the first fastener is composed of a thermoplastic material and the outer layer is composed of a fire-resistant material that provides flame-penetration resistance to the first fastener and the insulation layer.

8. The apparatus of claim 1, wherein the first fastener is disposed in the insulation blanket to increase a sealing engagement between the insulation blanket and the vehicle compartment frame to at least one of increase acoustic insulation, increase thermal insulation, and decrease moisture accumulation.

9. The apparatus of claim 1, wherein the outer layer and the insulation layer are composed of flexible materials to enable a first portion of the outer layer and an adjacent second portion of the insulation layer to be positioned along an inner surface of the first fastener to enable the first fastener to couple the insulation blanket to the vehicle compartment frame.

10. The apparatus of claim 1, wherein the outer layer is composed of a semi-rigid material, a portion of outer layer is positioned along an inner surface of the first fastener to enable the first fastener to couple the insulation blanket to the vehicle compartment frame, the semi-rigid material enables the outer layer of the insulation blanket to form a seal with a surface of the vehicle compartment frame.

11. An apparatus comprising:

a unitary fastener contained in a flexible insulation blanket to sealingly couple the insulation blanket to an aircraft compartment frame, the fastener including;

a first leg;

a second leg opposite the first leg; and

a middle portion extending between the first leg and the second leg,

wherein the first leg, the second leg, and the middle portion of the fastener define a channel that is to receive the aircraft compartment frame, the first leg and the second leg to engage the aircraft compartment frame to sealingly couple the insulation blanket to the aircraft compartment frame.

12. The apparatus of claim 11, wherein the fastener is fixedly coupled to the insulation blanket.

13. The apparatus of claim 11, wherein the fastener is contained in a cap strip extending along and protruding from a side of the insulation blanket.

14. The apparatus of claim 11, wherein the first leg and the second leg clamp a portion of the insulation blanket to the aircraft compartment frame to form a seal between the insulation blanket and the aircraft compartment frame.

15. The apparatus of claim 11, wherein the first leg and the second leg flex away from each other to enable the fastener to receive the aircraft compartment frame and, upon the fastener receiving the aircraft compartment frame, the first leg and the second leg are to flex toward each other to enable the fastener to clamp the insulation blanket to the aircraft compartment frame.

16. A method comprising:

disposing fasteners in an insulation layer of an insulation blanket along a first side of the insulation blanket, the fasteners spaced apart from each other along the first side;

enclosing the fasteners and the insulation layer in an outer layer to form the insulation blanket; and

forming the insulation layer and the outer layer to a channel defined by the fasteners extending along the first side of the insulation blanket, the channel to receive a first portion of a vehicle compartment frame to sealingly couple the insulation blanket to the vehicle compartment frame.

17. The method of claim 16, further including fixedly coupling the fasteners to the insulation layer along the first side of the insulation blanket.

18. The method of claim 16, wherein disposing the fasteners in the insulation layer along the first side of the insulation blanket includes disposing the fasteners in a cap strip that extends along the first side of the insulation blanket.

19. The method of claim 16, further including coupling a cap strip to a second side of the insulation blanket opposite the first side, the cap strip is to engage a second portion of the vehicle compartment frame to enable the second side of the insulation blanket to couple to the second portion of the vehicle compartment frame.

20. The method of claim 16, further including sealingly coupling the first side of the insulation blanket to the first portion of the vehicle compartment frame via the fasteners by receiving the first portion of the vehicle compartment frame in the channel defined by the fasteners.
