Abstract

PURPOSE: To increase both propulsion efficiency of a rudder and its effect, by providing a laterally protrusive blade end plate in a position of discontinuous shape of the rudder.
CONSTITUTION: In the surroundings of a reaction rudder 1 at its position 2 of discontinuous shape, a blade end plate 3 is laterally protrusively mounted. Protrusive length of the blade end plate 3 is only required for the extent enough to prevent a flow S2 tending to occur from a difference of pressures when pressure P2 on one face of a blade lowers and pressure P1 on the other face of the blade increases to generate a lift L, in this way efficiency of propulsion can be improved by a very slightly additional substance, further the rudder being of light weight and easily machined can be obtained at low cost.
