  • Publication number: 20210039773
    Abstract: [Object] To provide a noise reduction apparatus, an aircraft, and a noise reduction method capable of increasing the amount of noise reduction. [Solving Means] The noise reduction apparatus 1 includes a porous plate 2 disposed to face a fluid flow, the porous plate 2 including a bend region 5 bent toward an upstream side of the fluid flow. The bend region 5 is provided at the end portion 6 of the porous plate 2, and has a concave R-shape on an upstream side of the fluid flow. Although the direction of the fluid flow is typically deflected toward the outside from the center of the porous plate 2 due to the porous plate 2, the deflected fluid easily passes through the porous plate 2 since the porous plate has the bend region 5. Thus, the shear layer of the fluid flow is weakened, the noise induced by the vortex is reduced, and it is possible to increase the reduction amount of noise.
