EXPERIENCE IN THE CONTROL OF SHIPS BY RIGHT ANGLE DRIVE THRUSTERS

The theory of control of ships presents extremely complex problems and a general policy for their solution is proposed. Standard forms of charts governing propeller performance are analyzed and interpreted for three special cases--namely, constant rpm, constant torque, and constant power. The application of propeller characteristics to Steerable Right Angle Drive units is discussed in conjunction with accounts of some full scale experiments. The steering characteristics of ships, and in particular the motion of a scow in steady state turning, are reviewed. A suggested method for establishing an initial choice of power for tunnel bow thruster installations is developed by nondimensional analysis.
