Abstract
An asymmetric propulsion design using a single bladed propeller is proposed as a viable method for a Unmanned Undersea Vehicle (UUV) to obtain maneuvering capability in all 6 Degrees of Freedom (DOF) with a single actuator. This substantially reduces the cost of the UUV while enabling it to perform missions which could be assigned to an Autonomous Undersea Vehicle (AUV) or Remotely Operate Vehicle (ROV). However, they are also extremely expensive for most research applications. Current UUV architecture is either optimized for long endurance survey missions as AUVs or precise maneuvering as tethered ROVs. Both versions require several hull actuators to provide maneuvering capability in all 6 DOF.
Previous literature is focused on assessing the viability of the single bladed propeller. However, little work has been done to compare the viability of this propulsion system to a conventionally actuated AUV. There is also a gap in the design methodology for employing this novel propulsion system. This thesis seeks to close this gap by developing a dynamic simulation model for the single bladed propeller actuated AUV and comparing its performance against a similar AUV actuated by conventional fins and stern planes. A single bladed propeller actuated AUV is shown to provide similar performance to a conventionally actuated AUV while commanded to conduct large course and depth changes. However, additional design and operational consideration must be applied to the single bladed propeller to maximize its maneuvering potential.
