A PRACTICAL METHOD OF ANALYZING THE ACCELERATION AND DECELERATION OF SHIPS

A practical method of analysing the acceleration and deceleration of ships is presented with special reference to large vessels. The ship motion is described in terms of the advance coefficient of the propeller, gives the rate at which the propeller advances through the water during its unit revolution per second. The use of the time constant T is recommended as a reasonable measure of acceleration and deceleration from both a practical and theoretical point of view. Because of the lack of published data, the resutls of some calculations are presented. Space does not permit a detailed discussion of the problem, but the approach can be outlined.
