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.
