Abstract
The invention discloses an experimental device for forward propulsion efficiency of a hydrofoil. The experimental device comprises a floating body, a stepping motor, a crank guide rod mechanism and a hydrofoil swinging mechanism, wherein the hydrofoil swinging mechanism is arranged below the floating body; the stepping motor and the floating body float on water; and the hydrofoil swinging mechanism and the hydrofoil thereof are immersed in water. The stepping motor drives a crank to rotate to drive an upright guide rod to move up and down, so that the hydrofoil connected with the upright guide rod is enabled to move up and down and a wave action is simulated to generate forward propulsion; and the swing of the hydrofoil is limited within a certain angle due to the limit effect on a hydrofoil limit rod from the arc-shaped hole slot of a hydrofoil swing guide rail. The experimental device can conveniently test the forward propulsion efficiency of different types of hydrofoils at different swing angles in different wave height and wave frequency environments without a wave basin during the up-and-down motion of the hydrofoils.
