When the rotation of a ship's screw is reversed in its forward motion, the blade elements are generally in stalled condition. In such a condition, the action of the screw propeller is analysed, and the thrust in the aftward direction is obtained.
Assuming the virtual mass to be one-fifth of that of the ship, and the resistance to be proportional to the square of the velocity, the formulae for the time and the distance in the decelerated motion are developed in this paper.
