Title:
VENTILATION-BASED DRAG REDUCTION DEVICE AND MARINE VENTILATION-BASED DRAG REDUCTION SYSTEM COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2024/007442
Kind Code:
A1
Abstract:
A ventilation-based drag reduction device, comprising a main housing (71), a first fairing assembly (72), a second fairing assembly (73), and a flow isolation assembly (74). The main housing (71) consists of a first segment (711), a second segment (712), a third segment (713), and a fourth segment (714), wherein the first segment (711) is used as a gas inlet end. The first fairing assembly (72) consists of a plurality of first fairing plates (721) vertically arranged in a cavity of the second segment (712); the second fairing assembly (73) consists of at least one second fairing plate (731) vertically arranged in a cavity of the third segment (713); the flow isolation assembly (74) is disposed in the cavity of the third segment (713) and is located on one side of the second fairing assembly (73); and the fourth segment (714) is used as a gas outlet end. According to the ventilation-based drag reduction device, the first fairing assembly, the flow isolation assembly, and the second fairing assembly are used for cooperative fairing, thereby reducing the turbulence intensity of high-pressure gas at the moment the high-pressure gas is discharged via a gas outlet, and facilitating the formation of a stable isolation gas layer at the bottom of a hull.
