Abstract

Claims (59)

1. A wall structure for an aircraft, comprising:

a first wall section;

a second wall section comprising an aperture extending axially along an axis through the second wall section, the second wall section axially spaced from the first wall section;

a fastener system fastening the second wall section to the first wall section, the fastener system including a mount and a retainer, the mount connected to the first wall section and comprising a post that projects axially into the aperture; and

an air gap axially between the mount and the first wall section;

the retainer including a head and a spring clip connected to the head, the head axially engaging the second wall section, and the spring clip disposed in the aperture and mated with the post,

wherein:

the first wall section comprises a panel;

the second wall section comprises a liner covering the panel; and

the panel comprises a first skin, a second skin, and a cellular core between and connected to the first skin and the second skin; and

wherein the air gap extends axially between the mount and the first wall section while the second wall section is completely fastened to the first wall section by the fastener system.

2. The wall structure of claim 1 , wherein the spring clip is biased radially against the post.

3. The wall structure of claim 1 , wherein

the post comprises a groove; and

the spring clip comprises a ridge that projects radially into the groove.

4. The wall structure of claim 1 , wherein

the spring clip is one of a plurality of spring clips mated with the post;

the plurality of spring clips are arranged circumferentially about the axis forming a receptacle in the retainer; and

the post projects axially into the receptacle.

5. The wall structure of claim 1 , wherein the second wall section is retained axially between the mount and the retainer.

6. The wall structure of claim 1 , further comprising:

a grommet extending axially through the aperture between a first side and a second side;

the mount axially contacting the grommet at the first side; and

the retainer axially contacting the grommet at the second side.

7. The wall structure of claim 1 , wherein the mount further includes a spacer axially spacing the second wall section from the first wall section.

8. The wall structure of claim 7 , wherein the post projects axially out from the spacer into the aperture.

9. The wall structure of claim 1 , wherein

the mount further includes a base and a plurality of standoffs connected to the base; and

the plurality of standoffs are arranged circumferentially about the post and axially engage the second wall section.

10. The wall structure of claim 1 , wherein the mount further includes a rim bonded to the first wall section.

11. The wall structure of claim 1 , further comprising a second air gap axially between the mount and the second wall section.

12. The wall structure of claim 1 , wherein

the retainer further includes a spring element; and

the head axially engages the second wall section through the spring element.

13. The wall structure of claim 1 , wherein

the retainer further comprises a plurality of spring elements arranged circumferentially about the axis; and

the plurality of spring elements axially bias the head away from the second wall section.

14. The wall structure of claim 1 , wherein the liner comprises a thermal blanket.

15. A wall structure for an aircraft, comprising:

a first wall section;

a second wall section overlapping the first wall section, an aperture extending axially along an axis through the second wall section;

a fastener system fastening the second wall section to the first wall section, the fastener system including a retainer and a mount; and

an air gap axially between the mount and the first wall section;

the retainer including a head, a receiver and a plurality of spring elements connected to the head, the receiver projecting axially out from the head into the aperture, the plurality of spring elements arranged circumferentially about the receiver and axially biasing the second wall section towards the first wall section; and

the mount connected to the first wall section and projecting axially into a receptacle in the receiver,

wherein:

the first wall section comprises a panel;

the second wall section comprises a liner covering the panel; and

the panel comprises a first skin, a second skin, and a cellular core between and connected to the first skin and the second skin; and

wherein the air gap extends axially between the mount and the first wall section while the second wall section is completely fastened to the first wall section by the fastener system.

16. The wall structure of claim 15 , wherein

the mount comprises a post that projects axially into the receptacle; and

the receiver comprises a spring clip disposed in the aperture and projecting radially into a groove in the post.

17. A wall structure for an aircraft, comprising:

a nacelle panel;

a thermal blanket covering the nacelle panel, an aperture extending axially along an axis through the thermal blanket;

a fastener system fastening the thermal blanket to the nacelle panel, the fastener system comprising a mount and a retainer configured to clip onto the mount within the aperture, wherein the thermal blanket is retained and clamped axially between the mount and the retainer, and

an air gap axially between the mount and the nacelle panel;

wherein the air gap extends axially between the mount and the nacelle panel while the thermal blanket is completely fastened to the nacelle panel by the fastener system.
