Abstract
An unmanned aerial vehicle includes a tubular base structure, a motor having a stator, the stator being connected to the tubular base structure, an energy storage module configured to supply power to the motor, and at least one propeller driven by the motor, wherein the tubular base structure houses at least one cable for routing power or signals, or a fuel conduit or wire conduit.
Claims20
An unmanned aerial vehicle, comprising:
- a tubular base structure;
- at least two motors, each said motor having a stator and a rotor, and having a central axis of rotation, the stator of each said motor being connected to the tubular base structure such that the central axis of rotation of each said motor coincides with a central axis of the tubular base structure;
- an energy storage module configured to supply at least one of power or fuel to the at least two motors;
- and
- at least one propeller affixed to each said motor, wherein the at least one propeller is driven by the motor;
- wherein the tubular base structure defines a generally hollow passageway extending through the stator and the rotor of each said motor, the generally hollow passageway housing at least one cable for routing power or signals, or a fuel conduit or wire conduit.
