Beyond Aero's 'BYA-I One'
The BYA-I One uses a twin pusher-configured propfan system, a shift from the earlier ducted-fan arrangement, powered by six 400kW hydrogen fuel cells delivering a combined 2.4MW of power, with a total propeller shaft output of 950kW.
Gaseous hydrogen is stored at 700 bar in externally mounted tanks above the wing structure, with a refueling time of just 30 minutes. The aircraft emits only water vapor in flight, making it one of the cleanest propulsion concepts in business aviation today. A custom-designed Full Authority Digital Engine Control (FADEC) system ensures precise performance across all flight phases and will be certified under a TC Engine framework.
On performance, the numbers are compelling. The BYA-I One is designed to carry up to eight passengers over a range of 800 nautical miles at 300 knots, covering more than 80% of current European business aviation routes.
It has a maximum speed of 414 mph, a ceiling of 26,000 feet, and a takeoff ground roll of just 725 meters, short enough to serve constrained airports like London City, and can operate from grass, snow, and unpaved surfaces.
