Abstract

A single-unit nose cone for a ram air including: a dome portion located at a forward end of the single unit nose cone; a dome stand portion adjacent to the dome portion; a seat portion adjacent to the dome stand portion; and a stem portion adjacent to the seat portion and located at an aft end of the single-unit nose cone, wherein the dome portion, the dome stand portion, the seat portion, and the stem portion are composed from a single piece of material having a density of about 0.286 pound/cubic inch (7916 kilogram/cubic meter).

Claims (40)

1. A single-unit nose cone for a ram air turbine, comprising:

a dome portion located at a forward end of the single unit nose cone;

a dome stand portion adjacent to the dome portion;

a seat portion adjacent to the dome stand portion; and

a stem portion adjacent to the seat portion and located at an aft end of the single-unit nose cone,

wherein the dome portion, the dome stand portion, the seat portion, and the stem portion are composed from a single piece of material having a density of about 0.286 pound/cubic inch (7916 kilogram/cubic meter),

wherein a diameter of the dome seat portion is greater than a diameter of the dome stand portion, and

wherein the seat portion is interposed between the dome stand portion and the stem portion.

2. The single-unit nose cone of claim 1 , wherein the dome stand portion is interposed between the dome portion and the seat portion.

3. The single-unit nose cone of claim 2 , wherein the seat portion is interposed between the dome stand portion and the stem portion.

4. The single-unit nose cone of claim 1 , wherein the material is steel.

5. The single-unit nose cone of claim 1 , wherein the stem portion further includes an opening configured to operably connect to a turbine shaft of the ram air turbine, wherein the opening opens toward the aft end.

6. The single-unit nose cone of claim 5 , further comprising:

an opening extending from a peak of the dome portion at the forward end of the single unit nose cone to the opening.

7. A ram air turbine assembly, comprising:

a nose housing having a snap ring groove;

a single-unit nose cone within the nose housing and secured to the nose housing via a snap ring in the snap ring groove, the single unit nose cone comprising;

a dome portion located at a forward end of the single unit nose cone;

a dome stand portion adjacent to the dome portion;

a seat portion adjacent to the dome stand portion, wherein the snap ring secures the sing-unit nose cone within the nose housing via the seat portion; and

a stem portion adjacent to the seat portion and located at an aft end of the single-unit nose cone,

wherein the dome portion, the dome stand portion, the seat portion, and the stem portion are composed from a single piece of material having a density of about 0.286 pound/cubic inch (7916 kilogram/cubic meter).

8. The ram air turbine assembly of claim 7 , wherein the dome stand portion is interposed between the dome portion and the seat portion.

9. The ram air turbine assembly of claim 7 , wherein the seat portion is interposed between the dome stand portion and the stem portion.

10. The ram air turbine assembly of claim 8 , wherein the seat portion is interposed between the dome stand portion and the stem portion.

11. The ram air turbine assembly of claim 7 , wherein the material is steel.

12. The ram air turbine assembly of claim 7 , wherein the stem portion further includes an opening configured to operably connect to a turbine shaft of the ram air turbine, wherein the opening opens toward the aft end.

13. The ram air turbine assembly of claim 12 , wherein the single-unit nose cone further comprises: an opening extending from a peak of the dome portion at the forward end of the single unit nose cone to the opening.

14. The ram air turbine assembly of claim 13 , further comprising:

a preload bolt located within the opening.

15. A single-unit nose cone for a ram air turbine, comprising:

a dome portion located at a forward end of the single unit nose cone;

a dome stand portion adjacent to the dome portion;

a seat portion adjacent to the dome stand portion; and

a stem portion adjacent to the seat portion and located at an aft end of the single-unit nose cone,

wherein the dome portion, the dome stand portion, the seat portion, and the stem portion are composed from a single piece of material having a density of about 0.286 pound/cubic inch (7916 kilogram/cubic meter),

wherein a diameter of the dome seat portion is greater than a diameter of the dome stand portion, and

wherein the dome stand portion is interposed between the dome portion and the seat portion.

16. The single-unit nose cone of claim 15 , wherein the material is steel.

17. The single-unit nose cone of claim 15 , wherein the stem portion further includes an opening configured to operably connect to a turbine shaft of the ram air turbine, wherein the opening opens toward the aft end.
