A Flying Ring - Outdoor Experiments

The vehicle combines the advantages of a quadrotor (mechanically simple, robust hover capability, vertical takeoff and land, etc.) and a fixed wing vehicle (efficient high speed forward flight). The annular wing provides lift, enshrouds the propeller blades for safety, and can lead to noise reduction. The vehicle is autonomous. See [1] regarding manufacturing, [2,3] for modelling, [4,5] for state estimation, and [6] for the control algorithm. Specific power: Vehicle with flat plate (white) airfoil (mass = 0.717 kg): 116 W/kg at hover, 139 W/kg at 10 m/s Vehicle with e169-il (blue) airfoil (mass = 0.75 kg): 116 W/kg at hover, 100 W/kg at 10 m/s FMA Quadrotor (mass = 0.5 kg) [2,7] : 180 W/kg at hover, 300 W/kg at 10 m/s Previous "A Flying Ring" video:    • A Flying Ring  .
