Abstract
In one aspect the subject matter herein describes a cable tilt actuator for an aircraft propulsion unit. One embodiment comprises: a cable spool, fore and aft cable sections, a compression beam, a compression beam guide, and a linear actuator. As the linear actuator drives the compression beam, relative rotation is imposed between the compression beam and the spool. Described, in one aspect, is an embodiment configured to tilt an aircraft propulsion unit.
Claims19
An aircraft propulsion unit tilt actuator comprising a first cable section, wherein the tilt actuator is configured to convert linear motion to rotary motion using the first cable section, wherein the tilt actuator further comprises a second cable section, wherein the first cable section is configured to drive an aircraft propulsion unit in a first rotational direction when tension is applied to the first cable section and wherein the second cable section is configured to drive the aircraft propulsion unit in a second rotational direction when tension is applied to the second cable section.
An aircraft comprising:
- an aircraft propulsion unit tilt actuator comprising a first cable section, wherein the aircraft propulsion unit tilt actuator is configured to convert linear motion to rotary motion using the first cable section, wherein the tilt actuator further comprises a second cable section, wherein the first cable section is configured to drive a rotating portion in a first rotational direction when tension is applied to the first cable section and wherein the second cable section is configured to drive the rotating portion in a second rotational direction when tension is applied to the second cable section.
An aircraft dynamics control actuator comprising a first cable section, wherein the tilt actuator is configured to convert linear motion to rotary motion using the first cable section, wherein the tilt actuator further comprises a second cable section, wherein the first cable section is configured to drive a rotating portion in a first rotational direction when tension is applied to the first cable section and wherein the second cable section is configured to drive the rotating portion in a second rotational direction when tension is applied to the second cable section.
A rotary actuator comprising:
- a linear actuator;
- a cable spool;
- at least a first and second cable section;
- a compression beam, wherein the compression beam is configured to maintain tension on the first and second cable sections, and wherein the compression beam is configured to apply more tension to the first cable than the second cable when the linear actuator extends and apply more tension to the second cable than the first cable when the linear actuator retracts.
