Ascendance proposes a long-range, low-emission hybrid VTOL air taxi

VTOL(Vertical TakeOff Landing :垂直離着陸機)の長距離を可能にするAscendance社の新提案案件記事です。

近未来の航空機が続々と開発されて来ています♪ 

Right now, the entire electric VTOL scene is a house built on a foundation of faith. Faith that the hordes of researchers beavering away on next-gen battery technology will achieve an enormous energy density breakthrough, or faith that hydrogen fuel cell powertrains will prove safe, reliable and practical in an aviation context.

Both seem likely, eventually, but the urban air taxi industry is pushing to be up and running within five years, and right now there's no powertrain on the market that can keep these energy-intensive vertical-lift birds in the air long enough to be practical in a commercial sense.
