    摘要： A collapsible flying device (20) is provided having a housing including first and second housing sections (28, 32) forming an enclosure, and a motorized assembly (40) that includes a drive motor (304) and a drive shaft (120) driven by the drive motor (304). The drive shaft (120) matingly receives the first housing section (28) and is coupled to the second housing section (32), wherein operation of the drive motor (304) drives the drive shaft (120) to move the first housing section (28) from a closed position adjacent the second housing section (32) to an open position spaced from the second housing section (32). A rotor hub (132) is rotatingly driven by the drive motor (304). At least two rotor blades (52) are coupled thereto and positioned within the enclosure in a collapsed position when the first housing section (28) is in the closed position, and extend beyond the enclosure in an expanded position when the first housing section (28) is in the open position.

    摘要： Multi-rotor rotorcraft (10) comprise a fuselage (12), and at least four rotor assemblies (14) operatively supported by and spaced-around the fuselage (12). Each of the at least four rotor assemblies (14) defines a spin volume (24) and a spin diameter (26). Some multi-rotor rotorcraft (10) further comprise at least one rotor guard (50) that is fixed relative to the fuselage (12), that borders the spin volume (24) of at least one of the at least four rotor assemblies (14), and that is configured to provide a visual indication of the spin volume (24) of the at least one of the at least four rotor assemblies (14). Various configurations of rotor guards (50) are disclosed.
