    摘要: In a high-lift-device, a wing, and noise reduction device for a high-lift-device that are capable of reducing noise generated when a flap is extended, preventing deterioration of aerodynamics characteristic when retracting the flap, and preventing an increase in weight, a flap main body (5) disposed so as to be extendable/retractable relative to a main wing and a protruding portion (6A-1) that smoothly protrudes at least at the vicinity of one end portion of a positive-pressure surface (PS) of the flap main body (5) in a direction away from the flap main body (5) are provided.

    摘要: An aircraft flap 3 is equipped with: a flap body 8 which is provided so as to be deployable with respect to a main wing 2; and inclined portions 5 which are provided so as to protrude on the upper surface 301 of at least the end 40 on the outboard OTB side in the span direction D2 of the flap body 8, and are inclined to the aircraft axial direction D1; and a protruding portion 7 which protrudes smoothly from the lower surface 302 of at least the end 40 on the outboard side. The rear end 52 of each of the inclined portions 5 is located closer to the side end edge 301A of the end 40 in the span direction D2 of the flap body 8 than the virtual line VL that passes through the front end 51 of the inclined portion 5 and is parallel to the aircraft axis direction.

    摘要: [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.

    摘要: [Object] To reduce noise resulting from a wing tip vortex of a wing such as a flap.
    [Solving Means] A flap 3 of an aircraft includes a flap main body 8 provided to a parent wing 2 in a deployable manner, and a vortex generation portion 50 including a protruding member 5, the protruding member 5 being provided to protrude from an upper surface 301 at least at an end 40 of the flap main body 8 on an outboard side OTB in a span direction D2 and forming a predetermined angle to an axial direction D1 of the aircraft. A rear end 52 of the protruding member 5 is located on the side adjacent to a side-end edge 301A at the end 40 of the flap main body 8 in the span direction D2 relative to a virtual line VL passing through a front end 51 of the protruding member 5 and being parallel to the axial direction D1.
