| 摘要 | A shroud for an aircraft having a noise reducing material on or in an inner surface of the shroud adjacent to one or more tips of the propeller. The noise reducing material is preferably an electrospun nanomaterial, particularly a ridged composite acoustic nanofibre. The interior surface of the shroud may be provided with a plurality of sound deflectors configured to dissipate sound by reflection and refraction, and absorb sound into the shroud body. The sound deflectors may be ribs or arrangements of discrete reflector elements. | ||||||
