Durable modular unmanned aerial vehicle
First Claim
1. A motor hub assembly, comprising:
- a motor supported by a motor mount;
an outer protective structure circumscribing and spaced apart from the motor mount;
a plurality of spokes extending radially outward from the mount and extending at least between the mount and the protective structure, the plurality of spokes having a cross-sectional shape which is greater in a dimension parallel to a rotational axis of the motor than in a dimension perpendicular to the rotational axis of the motor such that the plurality of spokes are substantially more resistant to flexure out of a plane normal to the rotational axis of the motor than to flexure parallel to the plane normal to the rotational axis of the motor.

Abstract
An unmanned aerial vehicle (UAV) includes a fuselage that supports breakaway components that are attached using magnets. One component is a battery pack which powers the vehicle. Another component is a rotor set including two identical pod pairs that each support a motor and a propeller. Each motor is attached to a hub assembly that includes a plurality of spokes captured in a motor hub and sandwiched by a rigid motor printed circuit board on top and a rigid hub plate. The hub assembly construction is rigid in plane and functions to keep the motor firmly stable during operation. The hub assembly is compliant and resilient when impacted parallel to the plane. Other features of the pod pairs encage the otherwise dangerous spinning propeller. This allows the vehicle to operate with a higher level of safety than conventional UAVs.

16. A thrust pod assembly comprising:
-
a protective structure, the protective structure comprising; a pod top comprising; an inner hoop; an outer hoop; and a plurality of protective ribs connecting the inner hoop to the outer hoop; a pod bottom comprising an outer hoop; and a rim fastened to the outer hoop of the pod top and the outer hoop of the pod bottom; a motor mount; and a plurality of carbon fiber spokes, each spoke fastened at one end to the outer hoop of the pod bottom of the protective structure, the plurality of spokes constrained compressively substantially in plane by a top rigid hub plate and a bottom rigid hub plate.
