Counter rotating blades paired with a conical nose piece eliminate tail structures and brakes, resolving orientation and speed complexity trade-offs.
Segmented airflow channels direct wind to a turbine, driving a generator that recharges the vehicle battery during motion.
Aircraft detaches from floating base station to fly independently to land-based maintenance, resolving complex offshore repair logistics.
An airborne kite dynamically adjusts cable tension to counteract tower movements, reducing fatigue without complex mechanical dampers.
Power electronic converter drives main generator as motor to position wind turbine blades for load sensor calibration.
