It will be a balance between versatality / weight / footprint / manauvaribility. You may still add wings if you wish, but if you want it to be versatile and more useful, they better be able to fold up or swing into the frame. Not saying you cannot add wings, even though wings will not be required once future energy sources is perfected. For now the only reason to use wings is because a long range battery does not exist. So the point of economy in future will not be relevant. Economy will not be an issue once fuel cells, supercaps, battery tech advances to the stage where it can provide superior capacity, where charging it up wil not even cost a fraction what it would cost to fuel an ice engine or generator for that matter. ![]() ![]() City as well as in and around airport travel will be in great demand.Currently short hop non winged EVTOL's have demonstrated to work well in the set parameters with current batteries. You cannot simply dismiss the one over the other. Therefore wings will rule competitively for all of the greater travel distance Again EVTOL'S will have 2 distinct markets. Even if batteries ever could approach the ability of H2 Fuel Cells for distance, the logic still remains for travel distance efficiency using wing lift vs wasteful prop thrust downward hurting the lift up that it strives for with its body's negative lift tipping forward. The best future designs for any worthwhile travel with distance will use wings to save energy that extends the competitive economic reach. This however does NOT remove Winged efficiency economy & safety logic for the majority of the trip that is more than just short hops. You are correct in the lack of need for wings in the TO&L end phases of travel where the versatile maneuverability requirement exists. Eve hasn't put out range or top speed figures yet, so it's unclear how they'll compare.Īir taxi customers are unlikely to care much exactly what propulsion layout these things use, but service operators might well be attracted by lower cost and simplicity if the performance tradeoffs are The knowledge on the subject of eVTOL currently evolving with easy existing battery tech is one thing but it is overshadowed by the logic and wisdom in the understanding of the obvious future where Safety, Efficiency, and Economy win in the competition that wings will rule in because it can carry a load far better than a wasteful prop downwash can. The advantages here are probably weight, cost and complexity reductions – but the most likely disadvantage will be added drag in forward flight. With no tilting propulsion units to vector thrust, they simply use one set of lift fans and another set of forward fans. The redesign brings Eve back in line with other non-tilting lift & cruise designs like the Wisk Cora and the AutoFlight Prosperity, which are among the simplest of eVTOL airframe designs. The two pushers and cabin design stay fairly similar, but Eve has consolidated the two wings into one, placing four longitudinal propulsion pods along the wings to hang eight props fore and aft of the wing. Where the original Eve eVTOL design ran a two-wing canard setup, with eight vertical lift props to complement two pusher props on the back, it seems the company has decided to go with something a bit more conventional – if you can call any electric VTOL aircraft conventional at this point. Embraer spinoff Eve has changed tack on its eVTOL aircraft design, unveiling a new single-wing lift and cruise design, as well as a refreshingly utilitarian-looking mockup of its passenger cabin, at this week's Farnborough air show outside London.
