It is therefore a general purpose and object of the present invention to provide systems and methods for maneuvering an underwater vehicle by generating vehicle maneuvering forces from a propulsor of the vehicle. To attain this object, the present invention is configured for a ducted, pre-swirl propulsor such that the pitch angles of the stator blades of the upstream stator row can be varied. By varying the pitch angles of ...
This patent application discloses an apparatus that controls the wake of stator blades on an underwater vehicle. The apparatus comprises one or more stator blades, each with a movable trailing edge that when actuated in a controlled manner produces a periodic flapping motion upstream of a propulsion rotor. The controlled periodic flapping of the trailing edge fills the stator blade wake enough to overcome the stator blade's own drag and ...
