Abstract

A manufacture configured to and process for inhibiting, from wear, a lock in a latching system comprising: a gland surrounding an actuator translating the lock through: a first fixed lock receptor and a moveable lock receptor. The manufacture and process include: inhibiting a skewing, of a lock central axis of the lock with the lock translating through the first opening and the opening in the moveable lock receptor, away from substantially aligning with: a first central axis of a first opening of the first fixed lock receptor, and an actuator central axis of the actuator, via fitting a first translation guide into the first fixed lock receptor. Also included is inhibiting: wear of a gland around an actuator in the lock while translating, and leaking, past the gland, of an actuator fluid within the lock; and skewing of an actuator central axis of the actuator.

First claim

What is claimed is:

1. A manufacture configured to inhibit, from wear, a gland around an actuator in a latch system that comprises:
a first translation guide; and
a lock that comprises:
an outer diameter;
an interior chamber configured to hold an actuator fluid and the actuator;
a ratio, between a length of the first translation guide to the outer diameter of the lock, that exceeds 0.500, wherein the lock is configured to translate through:
the manufacture fitted within a first opening in a first fixed lock receptor of the latch system; and
an opening in a moveable lock receptor.

2. The manufacture of claim 1 , further comprising the first translation guide configured to prevent a gap that allows leakage, past the gland, of the actuator fluid from the lock.

3. The manufacture of claim 1 , further comprising a ratio, between the length of the first translation guide to a stroke distance of the lock, that exceeds 0.559.

4. The manufacture of claim 3 , further comprising:
the outer diameter of the lock comprising a dimension of 2.48 inches;
the length of the first translation guide being greater than 1.24 inches; and
the stroke distance of the lock comprising a dimension of less than 0.878 inches.

5. The manufacture of claim 1 , wherein the first translation guide comprises a copper-nickel-tin alloy shrunk-fit into the first opening.

6. The manufacture of claim 1 , further comprising:
the actuator comprising an actuator central axis;
the lock comprising a lock central axis;
the first opening comprising a first central axis; and
the first translation guide configured to hold the actuator central axis and the lock central axis substantially aligned with the first central axis.

7. The manufacture of claim 6 , further comprising the latch system comprising:
a second lock receptor that comprises a second opening that comprises a second central axis;
the moveable lock receptor, that comprises a moveable opening that comprises a central axis, the moveable lock receptor configured to rotate into a latched position located between the first fixed lock receptor and the second lock receptor; and
the first translation guide configured to hold the actuator central axis and the lock central axis substantially aligned with: the central axis of the opening in the moveable lock receptor in the latched position and the first central axis.

8. The manufacture of claim 6 , further comprising the first translation guide configured to inhibit the lock central axis from a skew away from an alignment from the first central axis.

9. The manufacture of claim 6 , further comprising the first translation guide configured to inhibit from wear, responsive to an inhibition of the lock central axis from a skew away from an alignment from the first central axis, the lock.

10. The manufacture of claim 7 , further comprising the first translation guide configured to inhibit, responsive to an inhibition of the lock central axis from a skew away from an alignment from the first central axis, from wear:
the first translation guide;
a translation guide fit in the opening of the moveable lock receptor; and
a second translation guide fit in the second opening.

11. A process for inhibiting, from wear, a lock in a latching system comprising a gland surrounding an actuator translating the lock through:
a first fixed lock receptor comprising a first opening; and
a moveable lock receptor comprising an opening, the process comprising: inhibiting a skewing, of a lock central axis of the lock with the lock translating through the first opening and the opening in the moveable lock receptor, away from substantially aligning with:
a first central axis of the first opening of the first fixed lock receptor, and
an actuator central axis of the actuator, via fitting a first translation guide into the first fixed lock receptor, wherein a ratio between a length of the first translation guide to a diameter of the lock exceeds 0.500.

12. The process of claim 11 , further comprising the first translation guide inhibiting leaking, past the gland, of an actuator fluid in the lock, while translating the lock through the first fixed lock receptor and the moveable lock receptor.

13. The process of claim 11 , further comprising a ratio, between the length of the first translation guide to a stroke distance of the lock, that exceeds 0.559.

14. The process of claim 11 , further comprising:
the first translation guide comprising a copper-nickel-tin alloy; and
shrink-fitting the first translation guide into the first opening.

15. The process of claim 11 , further comprising:
the lock comprising an outer diameter comprising a dimension of 2.48 inches;
the first translation guide comprising a length greater than 1.24 inches; and
a stroke distance of the lock comprising a dimension of less than 0.878 inches.

16. A process for inhibiting wear of a gland around an actuator in a lock translating through:
a first fixed lock receptor; and
a moveable lock receptor in a latched position, in a latching system, the process comprising inhibiting:
leaking, past the gland, of an actuator fluid within the lock; and
skewing of an actuator central axis of the actuator away from substantially aligning with:
a lock central axis of the lock; and
a first central axis of a first opening, via shrink-fitting a first translation guide into a first opening in the first fixed lock receptor, wherein a ratio between a length of the first translation guide to a diameter of the lock exceeds 0.500.

17. The process of claim 16 , further comprising:
inhibiting, via the first translation guide: wear of the lock, and skewing of the actuator central axis of the actuator away from substantially aligning with a central axis of the moveable lock receptor in the latched position adjacent to the first fixed lock receptor, with the lock translating through the moveable lock receptor in the latched position.

18. The process of claim 16 , further comprising a ratio, between the length of the first translation guide to a stroke distance of the lock, that exceeds 0.559.

19. A manufacturing system configured to inhibit wear in components of a latching system that comprises:
a lock configured to translate a stroke distance through a first translation guide in a first lock receptor that comprises a first opening and a moveable lock receptor that comprises a second opening, wherein the lock comprises:
an outer diameter;
an interior chamber configured to hold an actuator and an actuator fluid;
a ratio, between a length of the first translation guide to the outer diameter of the lock, that exceeds 0.500.

20. The manufacturing system of claim 19 , further comprising a machine configured to produce the first translation guide, configured to shrink-fit within the first opening, such that the first translation guide comprises a length of at least 1.24 inches, and the outer diameter of the lock comprises a dimension of 2.48 inches and the stroke distance that comprises a dimension of less than 0.878 inches.

21. A method for fabricating a portion of an aircraft comprising a manufacture configured to inhibit a wear of components of a latching system for a folding wing, the method comprising shrink-fitting a first translation guide into a first opening in a first lock receptor adjacent to a moveable lock receptor in a flight position in a folding wing system, such that the first translation guide comprises a length greater than 1.24 inches, and a lock in the latc
