The air taxi is fitted with hydrogen fuel cells that produce energy, power all on-board systems and 6 quiet electric outrunners optimized for low noise and low RPM. Skai provides an onboard tank of liquid hydrogen. It takes under 10 minutes to refill.
The car's velocity is 115 miles per hour. For local journeys, average speeds would typically be about 85 mph, in a straight line and with little traffic.
The company believes that between 10 and 150 miles would be the daily "sweet spot". However, as you count the time and hassle involved in traveling to the airport, passing through screening and other delays – longer on-demand travel with Skai is quite enticing.
Flying will last up to 4 hours, but it will take only minutes for most flights. Auxiliary fuel tanks for advanced applications will improve flight times depending on mission requirements. Up to 1000 pounds will hold the engine.
From the Skai website:
Skai is a radically simple air mobility system designed to go from A to Anywhere. It eliminates complexity for an unparalleled level of reliability and safety. It uses hydrogen fuel cells, to provide an energy solution that’s truly clean from end to end
Six pairs of brushless electric motors with no complex gearbox or tail-rotor link are used for Skai's six rotors. It's a simple, redundant device that can withstand and proceed to its destination with one rotor failure. The company says it would land comfortably even though it drops two rotors.
The three primary structures of Skai are triple redundant, rotors, fuel cells and flight computers, to ensure peace of mind on any ride.
The car can still land securely, even though several systems malfunction. Skai provides an extra fail-safe redundancy, an airframe fixed parachute, should a disastrous scenario arise.
