Abstract
The present disclosure provides a multi-rotor Aerial Vehicle comprising at least five arms. Pairs of coaxial contra rotating rotors/propellers are configured on each arm defining a polygon. In the event of failure of any one of the rotors/propellers, a control system incorporating an autopilot, shuts off corresponding contra rotating rotor/propeller of the pair to maintain yaw stability thereby rendering the corresponding arm non-functional; and adjusts throttles of the coaxial contra rotating rotors/propellers of remaining functional arms to maintain tilt and lift stability of the Aerial Vehicle.
Claims6
A multi-rotor Aerial Vehicle comprising:
- a frame having at least five arms;
- pairs of contra rotating coaxial rotors/propellers configured on each arm of the frame;
- and
- a control system incorporating an autopilot configured to control operation of the pairs of contra rotating coaxial rotors/propellers to maintain stability of the Aerial Vehicle;
- wherein the pairs of contra rotating coaxial rotors/propellers are configured such that lines joining the adjacent contra rotating coaxial rotors/propellers define a polygon of a configuration such that in event of any one pair of the pairs of the contra rotating coaxial rotors/propellers becoming non-functional, centre of gravity of the Aerial vehicle still lies within a polygon formed by lines joining the adjacent pairs of contra rotating coaxial rotors/propellers that remain functional;
- and
- wherein the control system is configured such that in event of failure of any one of the rotors/propellers of the pairs of contra rotating coaxial rotors/propellers, the auto pilot shuts off corresponding contra rotating rotor/propeller of the pair, rendering the corresponding pair of the contra rotating coaxial rotors/propellers non-functional, to maintain yaw stability.
