<p>A cycloidal propulsion unit for controlling a thrust vector includes a hub that rotates about a hub axis. Further, the unit includes an airfoil blade pivotally mounted on the hub along a blade axis parallel to the hub axis. As a result, the blade may pivot about the blade axis while traveling along a blade path during rotation of the hub. The unit further includes a ring that rotates around a ring axis parallel to the hub axis. The ring is interconnected with the blade via a control rod. Also, a device is engaged with the ring to selectively position the ring axis relative to the hub axis. As a result of these structures, selective positioning of the ring axis provides control of the rotation of the blade about the blade axis as the blade travels along the blade path.</p> |
