一种设备,其被构造成减小螺旋桨和定位在螺旋桨下游的飞行器表面之间的声学相互作用,包括飞行器表面的表面修改元件。表面修改元件限定表面的修改轮廓。修改轮廓被构造成将定位在至少一部分表面上的源场内的多个声音源的相位分布去相关。
An apparatus configured to reduce acoustic interactions between a propeller and a surface of an aircraft positioned downstream of the propeller includes a surface modification element of the surface of the aircraft. The surface modification element defines a modified contour of the surface. The modified contour is configured to decorrelate a phase distribution of a plurality of sound sources within a source field positioned on at least a portion of the surface.
