The invention relates to a parking apron with a super-structure sound barrier, which comprises a basic parking apron, a supporting wall body arranged around the basic parking apron and the super-structure sound barrier arranged on the supporting wall body, and the super-structure sound barrier at least comprises a super-structure sound absorption and/or sound insulation component with a plurality of lattice structures. The super-structure sound absorption and/or sound insulation component is configured to absorb or isolate low and medium frequency noise with the frequency spectrum larger than 200 Hz and smaller than 1000 Hz generated in the take-off and landing process of the vertical take-off and landing aircraft. Compared with the prior art, the super-structure sound absorption and/or sound insulation component can effectively isolate and absorb low and medium frequency noise generated by the rotor wings in the take-off and landing process of the vertical take-off and landing aircraft. Due to the fact that the metasurface is arranged around the parking apron, the metasurface has a certain isolation and protection effect on the aircrafts in the parking apron, and the influence of crosswind or crosswind outside the parking apron on the aircrafts is avoided.

    本发明涉及一种具有超构声屏障的停机坪,包括基础停机坪、设置于所述基础停机坪四周的支撑墙体,还包括设置于所述支撑墙体上的超构声屏障,所述超构声屏障至少包括具有多个晶格结构的超构吸声和/或隔声部件,所述超构吸声和/或隔声部件被配置为吸收或隔离垂直起降飞行器在起降过程中产生的频谱大于200Hz且小于1000Hz的中低频噪声。与现有技术相比,超构吸声和/或隔声部件在垂直起降飞行器起降过程中能够有效隔离与吸收旋翼产生的中低频噪声。由于超构声屏障设置在停机坪周围,对停机坪内的飞行器有一定隔离保护作用,避免停机坪外的侧风或横风对飞行器的影响。
