Abstract: PURPOSE: An installation method of a wing type flowing field internal type noise measuring device is provided to reduce a test preparing time by independently installing a noise measuring device inside a large cavitation tunnel. CONSTITUTION: An installation method of a wing type flowing field internal type noise measuring device is as follows. A sound detector(3) is mounted in one end part of a wing type body(1). The wing type body is attached on a wall surface of a large cavitation tunnel by using a clad board(14). The wing type body is controlled to be paralleled to a flowing direction of a large cavitation tunnel by turning a rotary shaft.

Abstract: PURPOSE: A wing type flowing field internal type noise measuring device is provided to more accurately measure noise inside a flowing field of a large cavitation tunnel by controlling increases of flow disturbance by a sound detector of the existing flowing field internal type noise measuring device itself and boundary layer flowing noise. CONSTITUTION: A wing type flowing field internal type noise measuring device comprises a wing type body(1) and sound detector(3). The sound detector mounted inside the wing type body measures noise inside a flowing field while being exposed to the flowing field. The wing type body has a cross section of a streamlined shape. A streamlined shape pod(2) is additionally mounted on one end part of the wing type body. The sound detector is mounted on a shear of the pod in which is projected more than the wing type body.
