Abstract

A multi-rotor Aerial Vehicle with least rotors / propellers and having single arm failure redundancy is disclosed. The AV comprises at least five arms with at least one arm having a co-axial pair of contra rotating rotors / propellers. To maintain yaw stability under normal conditions, half of rotors / propellers are rotated in one direction and other half in opposite direction. In the event of failureof any one of the rotors / propellers located adjacent to the pair of contra rotating rotors / propellers, the one propeller / rotor out of the contra rotating rotor / propeller that is rotating opposite to the failed rotor / propeller is shut off. In the event of failure of a rotor / propeller belonging to contra rotating rotors / propellers, other rotor / propeller of the pair is shut off. In the event of failure of any one of rotors / propellers not adjacent to contra rotating rotors / propellers, the RPMs of other rotors / propellers is adjusted to maintain stability and navigate the Aerial Vehicle.

Description

technical field [0001] This disclosure relates to the field of aircraft. More specifically, the present disclosure relates to a multi-rotor aircraft with a minimum number of rotors / propellers capable of maintaining stable flight even if one of its rotors / propellers and / or associated components fails for any reason. Background technique [0002] The Background Description includes information that may be used in understanding the present invention. It is not an admission that any of the information presented herein is prior art or relevant to the presently claimed invention, or that any publication cited, either expressly or implicitly, is prior art. [0003] An unmanned aerial vehicle (UAV) is a remote-controlled or autonomous aerial vehicle that can carry cameras, sensors, communications equipment, or other payloads, is capable of controlled, sustained level flight, and is usually powered by engines. Autopiloted UAVs can fly autonomously according to a pre-programmed flig...
