| 摘要 |
Disclosed herein is a propulsion system (300), which may be implemented in an air-vehicle (100), such as a ducted-fan organic air-vehicle. The propulsion system (300) comprises (a) a power source, (b) a fan located within a duct and powered by the power source, (c) a plurality of vanes (302) arranged in an x-clocked configuration and configured to produce control moments from the flow generated by the fan. The maximum control moments, which can be created by the vanes (302) in the x-clocked configuration, are substantially oriented along the flight axes of the air-vehicle (100) or the principle axis of the maximum moment of inertia. |
