Hyundai Motor Group’s advanced air mobility division, Supernal, revealed its electric vertical takeoff and landing (eVTOL) aircraft, the S-A2, at CES 2024. Designed for urban commutes of 20 to 40 miles, the S-A2 aims to bypass traffic congestion by taking to the skies.
Combining Airplane and Helicopter Advantages
Supernal CEO Jaiwon Shin highlighted the S-A2’s unique blend of airplane and helicopter features. It offers the smooth, safe in-flight experience of an airplane combined with the vertical takeoff and landing capabilities of a helicopter, ideal for navigating dense urban environments. Powered by a battery, the S-A2 prioritizes comfort, convenience, and clean operation.
From SA-1 Concept to S-A2 Reality
The S-A2, a V-tail aircraft, builds upon the SA-1 concept showcased at CES 2020. Its eight rotors enable vertical takeoff and then pivot forward for efficient cruising. Supernal projects a cruising speed of up to 120 mph and an altitude of 1,500 feet.
Design and Passenger Experience
Inspired by the eyes of a bee, the S-A2’s glassy cockpit and body provide pilots and passengers with panoramic views. The cabin accommodates up to four passengers in modular seats, adaptable for various configurations. Supernal’s meticulous design process involved evaluating 100 designs before selecting the final configuration that optimizes both redundancy and efficiency.
Addressing Battery Power Challenges
Overcoming the limitations of current battery technology was a key engineering hurdle. Chief Technology Officer Ben Diachun explained the S-A2’s significant power requirements during takeoff, comparable to a car accelerating from 0 to 60 mph in two seconds, sustained for 30 seconds. Despite this high power usage, Supernal claims a takeoff noise level of just 65 decibels, similar to a dishwasher. The aircraft’s modular design allows for future battery upgrades as technology advances.
Operational Plans and Future Outlook
Supernal envisions operating the S-A2 from vertiports, strategically located hubs within urban areas. The company is committed to meeting commercial aviation safety standards and collaborating with aviation authorities to establish operational procedures. While a 2028 launch is targeted, Supernal has not yet specified the initial markets.
Conclusion
Supernal’s S-A2 presents a compelling vision for the future of urban air mobility. By combining innovative design, electric propulsion, and a focus on safety and efficiency, Supernal aims to revolutionize short-haul travel in congested urban areas. While challenges remain, the S-A2’s unveiling at CES 2024 marks a significant step toward realizing this ambitious goal.
