A multi-rotor rotorcraft (10) includes a fuselage (12) and at least four rotor assemblies (14) operably supported by the fuselage (12) and spaced about the fuselage (12). Each of the at least four rotor assemblies (14) defines a rotational volume (24) and a rotational diameter (26). Some multi-rotor aircrafts (10) also include at least one rotor shroud (50) fixed relative to the fuselage (12), therotor shroud (50) defining a rotational volume (24) of at least one of the at least four rotor assemblies (14) and being configured to provide a visual indication of the rotational volume (24) of theat least one of the at least four rotor assemblies (14). Various configurations of a rotor shroud (50) are disclosed herein. 本申请公开了一种多旋翼旋翼机(10)，其包括机身(12)和至少四个旋翼组件(14)，所述至少四个旋翼组件(14)由机身(12)可操作地支撑并围绕机身(12)间隔开。至少四个旋翼组件(14)中的每一个限定旋转体积(24)和旋转直径(26)。一些多旋翼旋翼机(10)还包括相对于机身(12)固定的至少一个旋翼护罩(50)，所述旋翼护罩(50)界定至少四个旋翼组件(14)中的至少一个的旋转体积(24)，并且被构造为提供至少四个旋翼组件(14)中的至少一个的旋转体积(24)的视觉指示。公开了旋翼护罩(50)的各种构造。
