Optimized Thrust Allocation of Variable-pitch Propellers Quadrotor Control: A Comparative Study on Flip Maneuver

Abstract: Variable-pitch propellers quadrotors possess nonlinear algebraic relations between force/moment of the system and thrust factors of the rotor dynamics. The nonlinear relations make the ...

SOAPdrones variable pitch quadcopter uses petrol power for heavy-lifting endurance

What does it take for a quadcopter to carry a 10-kg (22-lb) payload and fly for three hours straight? It takes petrol power – and a clever variable pitch rotor system that makes this gas-powered drone ...
