The present invention relates to a device for multi directionally measuring the velocity of a wake stream of a propeller in a model ship, which comprises: a base where a penetrating hole is formed; a rotating member which is installed in the penetrating hole to be able to rotate, and has an elevating unit therein, capable of moving a first block along a longitudinal direction; a horizontal guide member which has a horizontal rail capable of moving a second block, connected with the first block through a shaft, to the left and the right; vertical guide members which are installed on both sides of the base and have a vertical rail capable of moving a third block, connected with both ends of the horizontal rail, up and down; and a measuring instrument which is installed in the second block in order to measure the velocity of a propeller in a model ship. Therefore, the device for multi directionally measuring the velocity of a wake stream of a propeller in a model ship can provide data applicable to actual ships by rotating the measuring instrument to various positions or changing the position thereof in order to accurately measure the flow distribution around the propeller installed at the stern of the model ship. |
