Abstract

A nosecone assembly having an axially extending centerline is provided. The assembly includes a nosecone body and at least one access panel. The nosecone body has at least one wall that defines an interior cavity. The wall has an interior surface contiguous with the interior cavity, and at least one window aperture extending through the wall. The access panel has first and second face surfaces. The access panel is attached to the wall interior surface within an attachment region that includes first and second attachment region portions partially contiguous with one another. The first and second attachment region portions define an interior unattached region, and the interior unattached region is aligned with the window aperture.

Claims (32)

1. A nosecone assembly having an axially extending centerline, the assembly comprising:

a nosecone body having at least one wall extending between a forward end and an aft end, the at least one wall at least in part defines an interior cavity of the nosecone body, the at least one wall having an interior surface contiguous with the interior cavity, and at least one window aperture extending through the at least one wall; and

at least one access panel having a first face surface and an opposite second face surface, a first end, a second end, a first lateral edge, and a second lateral edge, wherein the first lateral edge extends between the first end and the second end, and the second lateral edge extends between the first end and the second end;

wherein the at least one access panel is attached to the wall interior surface within an attachment region that includes a first attachment region portion partially contiguous with a second attachment region portion, the first attachment region portion and the second attachment region portion collectively define an interior unattached region disposed between at least a length of the first attachment region portion and at least a length of the second attachment region portion, and wherein the interior unattached region is aligned with the at least one window aperture; and

wherein the first lateral edge extends a first distance between the first end and the second end, and the first attachment region portion extends a second distance along the first lateral edge from the second end towards the first end, where the second distance is less than the first distance.

2. The nosecone assembly of claim 1 , wherein the second lateral edge extends a third distance between the first end and the second end, and the second attachment region portion extends a fourth distance along the second lateral edge from the second end towards the first end, where the fourth distance is less than the third distance.

3. The nosecone assembly of claim 2 , wherein the attachment region is “U” shaped, with the interior unattached region disposed within the “U” shape.

4. The nosecone assembly of claim 2 , wherein the attachment region is “V” shaped, with the interior unattached region disposed within the “V” shape.

5. The nosecone assembly of claim 1 , wherein the at least one access panel comprises an elastomeric material.

6. The nosecone assembly of claim 5 , wherein the at least one access panel is disposable in a normal state wherein at least a portion of the at least one access panel is biased against the wall interior surface, and is configured to elastically return to the normal state.

7. The nosecone assembly of claim 1 , wherein the first lateral edge and the second lateral edge converge toward one another in a direction from the first end towards the second end.

8. The nosecone assembly of claim 7 , wherein the first lateral edge and the second lateral edge collectively form a “V” shape in proximity to the second end.

9. The nosecone assembly of claim 1 , wherein the first end extends a first end distance between the first lateral edge and the second lateral edge, and the second end extends a second end distance between the first lateral edge and the second lateral edge, and the first end distance is greater than the second end distance.

10. The nosecone assembly of claim 1 wherein the at least one access panel includes a protrusion shaped to mate with the at least one window aperture.

11. The nosecone assembly of claim 1 , wherein the at least one access panel includes a protective substrate attached to the first face surface, and positioned to align with the at least one window aperture.

12. A nosecone assembly having an axially extending centerline, the assembly comprising:

a nosecone body having at least one wall extending between a forward end and an aft end, the at least one wall at least in part defines an interior cavity of the nosecone body, the at least one wall having an interior surface contiguous with the interior cavity, and at least one window aperture extending through the at least one wall; and

at least one access panel having a first face surface and an opposite second face surface, a first end, a second end, a first lateral edge, and a second lateral edge, wherein the first lateral edge extends between the first end and the second end, and the second lateral edge extends between the first end and the second end;

wherein the at least one access panel is attached to the wall interior surface within an attachment region that includes a first attachment region portion partially contiguous with a second attachment region portion, the first attachment region portion and the second attachment region portion collectively define an interior unattached region, and wherein the interior unattached region is aligned with the at least one window aperture; and

wherein the first lateral edge extends a first distance between the first end and the second end, and the first attachment region portion extends a second distance along the first lateral edge from the second end towards the first end, where the second distance is less than the first distance.

13. The nosecone assembly of claim 12 , wherein the at least one access panel comprises an elastomeric material.

14. A gas turbine engine, comprising:

a fan section;

a nosecone assembly connected to the fan section, the nosecone assembly having an axially extending centerline, the assembly comprising:

a nosecone body having at least one wall extending between a forward end and an aft end, the at least one wall at least in part defines an interior cavity of the nosecone body, the at least one wall having an interior surface contiguous with the interior cavity, and at least one window aperture extending through the at least one wall; and

at least one access panel having a first face surface and an opposite second face surface, a first end, a second end, a first lateral edge, and a second lateral edge, wherein the first lateral edge extends between the first end and the second end, and the second lateral edge extends between the first end and the second end;

wherein the at least one access panel is attached to the wall interior surface within an attachment region that includes a first attachment region portion partially contiguous with a second attachment region portion, the first attachment region portion and the second attachment region portion collectively define an interior unattached region disposed between at least a length of the first attachment region portion and at least a length of the second attachment region portion, and wherein the interior unattached region is aligned with the at least one window aperture; and

wherein the first lateral edge extends a first distance between the first end and the second end, and the first attachment region portion extends a second distance along the first lateral edge from the second end towards the first end, where the second distance is less than the first distance.

15. The gas turbine engine of claim 14 , wherein the second lateral edge extends a third distance between the first end and the second end, and the second attachment region portion extends a fourth distance along the second lateral edge from the second end towards the first end, where the fourth distance is less than the third distance.

16. The gas turbine engine of claim 14 , wherein the at least one access panel comprises an elastomeric material.

17. The gas turbine engine of claim 16 , wherein the at least one access panel is disposable in a normal state wherein at least a portion of the at least one access panel is biased against the wall interior surface, and is configured to elastically return to the normal state.

18. The gas turbine engine of claim 14 , wherein the attachment region is “U” shaped, “V” shaped, or “crescent” shaped, with the interior unattached region respectively disposed within the “U” shape, “V” shape, or “crescent” shape.
