Single Rotor based Vertical Take Off and Landing systems are more prone to stability issues than normal aircraft. The main factors causing instability are anti torque, pitching and rolling. Anti torque, which causes the body of the aircraft to turn in the opposite direction to the rotor, is generated as the engine turns the rotor against the air. Pitching and rolling, on the other hand, can be caused...
This paper introduces the distributed flight array (DFA) which is being developed at ETH Zurich. This multi-rotor platform consists of autonomous rotor modules that are able to drive, dock with their peers, and fly in a coordinated fashion. These modules are organized as distributed computational units with minimal sensory input. This is a complex system that is rich in dynamics with much room to...
This paper describes the theory and experiments of a new technology for propelled thrusters. The principle is to extend the potentialities of magnetic-coupling motor shafts by adding degrees of freedom in their kinematics. The idea is to redirect the propeller and therefore, the thrust to another direction without adding or moving any motors. The focus of this work is to understand how does behave...
