It’s finally here – today we unveiled S-A2, our latest eVTOL vehicle product concept. Combining Supernal’s cutting-edge aerospace engineering with Hyundai Motor Group’s human-centered design expertise, S-A2 is a four-passenger, eight-rotor, battery electric vehicle. Its unique all-tilting rotor configuration reduces complexity and maximizes efficiency for all phases of flight. And we’re building it to meet the highest commercial aviation safety standards.

This is more similar to Joby 6 tilt arrangement than Archer Midnight and that’s not necessarily a bad thing. Still no cyclic or flapping so likely reduced control authority compared to a helicopter. No autorotation. Rear props are awfully low to the ground and “people level”. They might ingest wake during transition and will during cruise. I’m sure there was significant debate over 4 vs 5 blades and vibration levels. Good to see rigid two bladed stopping lift props get dropped. That’s not a design configuration that scales well. Still too many rotors and blades. Two rotors and a wing is the “chef’s kiss”. ☺️

Damn, that design 🔥🔥🔥🔥🔥

Interesting configuration, but tilting rotors add complexity and more rotors mean more maintenance and inspections.

For noise, the full article mentions 65 dB at take-off and landing, and 45 dB at a cruise of 1500 ft. With 8 propellers, this sounds good, but noise is a multi-faceted metric and one needs more specifics to see its comparative performance with other eVTOLs, like, what distance at T/O & L is it measured, is this peak SPL or Peak Perceived Noise Level or EPNL or what, what does the frequency spectrum look like, etc.? Have these details been published elsewhere? Thanks.

What is the purpose of both tilt-up and tilt-down propellers rather than other all tilt-up-propeller eVTOL designs? It looks like puller-pusher props for vertical flights. Is it just to set itself apart and unique from current-day eVTOLs, or does it serve any performance function, like, improved stability in flight transition, or whatever?

Fantastic solution, we are pleased to support your success!

The torsional load on the wing during vertical takeoff must be huge.
