Abstract:

This thesis describes the development and execution of a test program to determine the suitability of an asymmetric propeller for unmanned underwater vehicles UUV. Woods Hole Oceanographic Institute reevaluated the concept for use on a UUV, but for two different objectives. The first was a possible improvement in propulsive efficiency. By controlling the speed of the propeller through each revolution, the thrust at any given point can be controlled. This allows for anon-uniformly distributed thrust about the longitudinal axis of the UUV which can be used to steer the UUV.
