Anti-drive mechanism for rise and fall rotating control systems

1. A rotor blade system, comprising:

a hub assembly pivotally attached to a rotor blade;

a mast attached to the hub assembly;

a swashplate engaged with the mast, the swashplate having:

a non-rotating ring; and

a rotating ring;

an anti-drive link system comprising:

a first and second link configured to extend relative to each other and form a gap therebetween;

wherein the anti-drive link system is pivotally engaged with a transmission top case and pivotally engaged with the non-rotating ring;

wherein the anti-drive system pivotally engages with a single drive point extending from the non-rotating ring;

wherein the mast extends thorough the gap; and

wherein the anti-drive link system is configured to raise and lower the swashplate along the mast.

2. The system of claim 1 , further comprising:

a drive system configured to drive the anti-drive link system, which in turn raises and lowers the swashplate along the mast.

3. The system of claim 2 , wherein the drive system is a hydraulic system.

4. The system of claim 1 , further comprising:

a cross link configured to engage with the first and second link.

5. The system of claim 1 , further comprising:

a third link pivotally engaged with the first and second links;

wherein the third link is pivotally attached to the non-rotating ring.

6. The system of claim 5 , wherein the third link is pivotally engaged with a drive point extending from the non-rotating ring.

7. The system of claim 5 , further comprising:

a shaft fixedly attached to the third link and configured to pivotally engage with the first and second links.

8. The system of claim 1 , wherein the anti-drive link system is configured to raise and lower the swashplate the entire collective stroke along the mast.

9. A rotor blade system, comprising:

a hub assembly pivotally attached to a rotor blade;

a mast attached to the hub assembly;

a swashplate engaged with the mast, the swashplate having:

a non-rotating ring; and

a rotating ring;

an anti-drive link system pivotally engaged with a transmission top case and pivotally engaged with the non-rotating ring, the anti-drive link system, having:

a first and second link configured to extend relative to each other and form a gap therebetween;

wherein the anti-drive system pivotally engages with a single drive point extending from the non-rotating ring;

wherein the mast extends thorough the gap; and

wherein the anti-drive link system is configured to raise and lower the swashplate along the mast.

10. The system of claim 9 , further comprising:

a drive system configured to drive the anti-drive link system, which in turn raises and lowers the swashplate along the mast.

11. The system of claim 10 , wherein the drive system is a hydraulic system.

12. The system of claim 9 , further comprising:

a cross link configured to engage with the first and second link.

13. The system of claim 9 , further comprising:

a third link pivotally engaged with the first and second links;

wherein the third link is pivotally attached to the non-rotating ring.

14. The system of claim 13 , wherein the third link is pivotally engaged with a drive point extending from the non-rotating ring.

15. The system of claim 13 , further comprising:

a shaft fixedly attached to the third link and configured to pivotally engage with the first and second links.

16. A method to raise and lower a swashplate along a mast, comprising:

providing the anti-drive link system of claim 9 ;

positioning the mast within the gap formed by the first and second links;

raising and lowering the swashplate along the mast via the anti-drive link system.

17. The method of claim 16 , further comprising:

raising and lowering the swashplate with a drive system via the anti-drive link system.
