New Generation of a Light Helicopter/eVTOL for the AAM Advanced Air Mobility Market
For the future AAM Advanced Market and UAM Urban Advanced Market, almost exclusively battery-powered eVTOLs are being offered asair taxis today.
They have been advertised with the slogan “Zero Emission” to attract investors, which has worked well for the first projects. However, weaknesses areslowly emerging in electric flight.
Most developers no longer write “Zero Emission,” but only “Zero Emission Flight“. In many places, electricity is still not produced greenly, but through,for example, coal-fired power plants. Additionally, eVTOLs require large and heavy batteries for a relatively short flight, and lithium extraction requiresenergy. Lithium is not inexhaustible, and 65% of lithium reserves are controlled by China. The eVTOL batteries have low cycles and a short lifespan.Batteries for eVTOLs are not only heavy but also expensive, which will drive operating costs up. Batteries for eVTOLs cannot be compared to batteriesfor electric cars. The battery industry invests in the development of car batteries because it is a multi-billion-dollar business, whereas eVTOLs are still asmall market. The super battery does not exist today, nor will it tomorrow.
eVTOL developers have focused on futuristic design, new propulsion systems such as tilt wings, tilt rotors, or multi-copter concepts, and pure batterypower. Cars, on the other hand, have remained practically unchanged, and most of them are still gasoline-powered. Going from 0 to 100 takes courage,and we are grateful for pioneers, but it is a long way until such projects prove themselves or receive certification. The greatest advantage of flying purelyelectrically with “Zero Emission” is also the greatest disadvantage. It is not because of the electric motors; they are already small wonders thatimmediately unleash full power (torque), make no noise, produce no CO2, consist of few parts, and require practically no maintenance. But they requireelectricity…
