Dynamic Performance of Small Diameter Tunnel Thrusters

Abstract

The transient response of a small tunnel thruster is studied for step changes in applied voltage to the thruster motor. Previous work on positioning remotely operated vehicles with a ducted propeller had shown that lags in the thruster response caused limit cycling in the vehicle's behavior. These experiments have shown that the influence of the fluid inertia in the tunnel is significant and changes the lagging response to a leading response with a large transient peak following the step input. It is conjectured that such thrusters will enhance vehicle stability.
