| Abstract |
When a marine express is levitated or attracted at
standstill and then propelled underwater, a pitching motion is
caused inevitably due to a torque produced by thrust force
around the center of gravity. In addition, some other
disturbances such as the water flow or undersea currents may
also cause this undesirable motion. In this paper, we will show
that using an air-core electromagnet the pitching is actively and
effectively damped in the highly unstable attractive mode, when
the water buoyancy is larger than the vehicle’s weight, which is
likely the case for a real marine express. |
