Abstract
A control link disposed to transfer rotor shaft rotation from an elongate element rotatable with a shaft to a rotatable element is provided and includes a structure terminating at a first end thereof as a mating element, which is securable to the elongate element such that the elongate element is rotatable about an axis defined through the mating element and such that a moment reaction in opposition to structure rotation about the elongate element is generated and a rod coupled to the rotatable element being and configured to be coupled to a second end of the structure at variable distances relative to the rotatable element.
Claims16
A control link disposed to transfer rotor shaft rotation from a walking beam rotatable with the rotor shaft to a rotating swashplate, the control link comprising:
- a structure including:
- a first sidewall and a second sidewall terminating at respective first ends as mating elements which are securable to the walking beam such that the walking beam is rotatable about an axis defined through the mating elements and such that a moment reaction in opposition to structure rotation about the walking beam is generated, the first sidewall and the second side wall being convergent toward one another at respective second ends and connecting to each other at their second ends to define a through-hole,
- rib members connected to each of the first sidewall and second sidewall between the first ends and second ends;
- and
- a rod coupled to the rotating swashplate and configured to be coupled to a second end of the structure and to the rib members at variable distances relative to the rotating swashplate.
