Abstract
The Dorado semi-submersible remote minehunting vehicle requires increased pitch, roll, and depth control while towing its sonar at depth. The vehicle controls both pitch and roll using independently deflectable sternplanes. Depth is controlled with foreplanes. New fore and sternplane designs are proposed which double control authority with about a 20% increase in span length and a 60% increase in average chord length. The new designs require from 3 to 4 times more actuator torque to achieve control and the actuator shaft bending moment will be up to 4 times larger. However, the new plane designs should allow the vehicle to maintain depth and equilibrium with only moderate control deflections while towing the sonar at depth.
