An electric vertical take-off and landing (eVTOL) aircraft is a variety of VTOL (vertical take-off and landing) aircraft that uses electric power to hover, take off, and land vertically. This technology came about owing to major advances in electric propulsion (motors, batteries, fuel cells, electronic controllers) and the emerging need for new aerial vehicles for Advanced Air Mobility and Urban Air Mobility that can enable greener and quieter flights. Electric and hybrid propulsion systems (EHPS) have also the potential of lowering the operating costs of aircraft.{{cite report |author= Le Bris, G |display-authors= etal |date= 2022 |title= ACRP Research Report 236: Preparing Your Airport for Electric Aircraft and Hydrogen Technologies |work= Transportation Research Board |location= Washington, DC |url= https://nap.nationalacademies.org/catalog/26512/preparing-your-airport-for-electric-aircraft-and-hydrogen-technologies }}{{rp|1–2}}
Original eVTOL aircraft designs are being developed by original equipment manufacturers (OEMs) that include legacy manufacturers such as Airbus, Boeing,{{Cite web|title=Boeing: Autonomous Flying Taxi: EVTOL Unmanned Solar Aircraft System|url=https://www.boeing.com/features/frontiers/2019/autonomous-flying-vehicles/index.page|access-date=2020-08-27|website=www.boeing.com}} Embraer, Honda, Hyundai, and Toyota, as well as several start-up companies including Archer Aviation, EHang, Joby Aviation, Overair, and Volocopter. This ecosystem of firms developing eVTOLs includes also spin-off of legacy aircraft manufacturers, such as Eve Air Mobility that emerged from the EmbraerX division of Embraer, as well as partnerships, such as Wisk Aero that was launched as a joint venture between Boeing and Larry Page's Kitty Hawk.
History

The concept of eVTOL aircraft emerged in 2009 when a video of the NASA Puffin eVTOL concept{{Citation|title=NASA Puffin Low Noise, Electric VTOL Personal Air Vehicle| date=11 November 2009 |url=https://www.youtube.com/watch?v=rhpPhvWvLgk|language=en|access-date=2021-11-04}} went viral on November 11, 2009, showcasing a single person concept rendering of the technology, and concept in flight. Following this, the first Puffin paper at the VFS Specialists Conference on Aeromechanics, on January 9, 2010. This concept utilized a new technology developed at NASA called Distributed Electric Propulsion (DEP).

In 2020, Tetra Aviation won the "disruptor award" at the GoFly personal flight contest for its single-seat eVTOL. In 2021, the company announced its Mk5 personal eVTOL that it expects to deliver in 2022. It incorporates 32 vertical lift rotors distributed across long, thin front and rear wings, along with a rear pusher prop for cruising. It uses a mostly aluminum frame, with carbon-fiber/aramid-reinforced polymer bodywork. The craft is {{Convert|8.62|m|abbr=on}} wide, {{Convert|6.15|m|abbr=on}} long and {{Convert|2.51|m|abbr=on}} high. The battery pack holds 13.5-kWh. Empty weight is {{Convert|488|kg|abbr=on}} and hosts an up to {{Convert|79|kg|abbr=on}} pilot. The vehicle features at least three flight controllers, driving 32 vertical propellers in the case of motor or flight controller failure, with a parachute in the event of total failure. The plane is to be sold as an experimental kit aircraft that requires only a private pilot license.{{Cite web|last=Blain|first=Loz|date=2021-08-04|title=Tetra Aviation debuts single-seat buy 'n' fly personal eVTOL|url=https://newatlas.com/aircraft/tetra-aviation-mk5-evtol/|access-date=2021-08-08|website=New Atlas|language=en-US}}

Technology

Many designs operate without wings. Multicopters typically use radial arms to host the motors/propellers, such as the Volcopter 2X or the Jetson One.{{Cite web|last=Blain|first=Loz|date=2021-10-21|title=Jetson One personal eVTOL looks like a ton of fun to fly|url=https://newatlas.com/aircraft/jetson-aero-personal-evtol/|access-date=2021-10-23|website=New Atlas|language=en-US}}
Vectored thrust designs change the direction of thrust, vectoring thrust vertically for takeoff/landing and horizontally while cruising. The entire wing (tilt-wing) can pivot to or just the rotors (tilt-rotor).

Craft Aero is notable for its box wing that is attached to the bottom of the fuselage in the front and the top of the fuselage in the back, presenting a diamond shape when viewed from above. The design includes a turbine generator for increased range.{{Cite web|last=Blain|first=Loz|date=2021-09-21|title=Craft Aero proposes a new type of blown diamond box-wing 9-seat eVTOL|url=https://newatlas.com/aircraft/craft-aero-evtol-diamond-blown-wing/|access-date=2021-09-21|website=New Atlas|language=en-US}} Odys Aviation vectors thrust from its 16 motors by extending flaps that direct the backward-traveling air downward at take-off and landing.{{Cite web|last=Blain|first=Loz|date=2022-02-15|title=Co-founder James Dorris explains Odys Aviation's unique VTOL design|url=https://newatlas.com/aircraft/odys-evtol-interview-james-dorris/|access-date=2022-02-16|website=New Atlas|language=en-US}}

Typical multicopters do not use wings, relying exclusively on the turning blades for lift though they may incorporate them to varying degrees.
Tandem wing designs use front and rear wings, optionally attached to each other at the wing tips.
Box wing or closed wing designs also use two wings, but the wings are connected in such a way that the wingtips are eliminated. The wings may be vertically stacked or arranged front and rear as in tandem designs.
Ducted wing designs open to expose the lift-off fans, and close around them for faster higher-speed cruising.{{Cite web |last=Blain |first=Loz |date=2022-07-25 |title=Horizon presents a 50% scale prototype of its badass Cavorite X5 eVTOL |url=https://newatlas.com/aircraft/horizon-cavorite-evtol-prototype/ |access-date=2022-07-27 |website=New Atlas |language=en-US}}

Most current designs are powered by batteries, although some designs use hydrogen fuel cells. Currently, batteries suffer from low specific energy (causing range and thus safety issues). Fuel cells have previously suffered from lower specific power (which could be too low for vertical takeoff/landing), but newer designs claim to have solved this problem with much higher specific power.{{cite web |title=HyPoint and Piasecki reach $6.5M deal to develop hydrogen fuel cells systems for eVTOLs |url=https://techcrunch.com/2021/08/24/hypoint-and-piasecki-reach-6-5m-deal-to-develop-hydrogen-fuel-cells-systems-for-evtols |website=TechCrunch|date=24 August 2021 }}{{cite web |title=Why Are Batteries a Problem for eVTOLs? |url=https://www.aviationtoday.com/2021/05/14/why-are-batteries-a-problem-for-evtols/ |website=Aviation Today |language=en |date=14 May 2021}}{{Cite web|title=HyPoint advances eVTOL hydrogen fuel cell system with working prototype|url=https://evtol.com/news/hypoint-advances-evtol-hydrogen-fuel-cell-system-with-working-prototype/|access-date=2021-12-28|website=evtol.com|language=en-US|archive-date=2022-01-23|archive-url=https://web.archive.org/web/20220123130745/https://evtol.com/news/hypoint-advances-evtol-hydrogen-fuel-cell-system-with-working-prototype/|url-status=dead}}{{Cite web|date=2020-05-31|title=HyPoint's "turbo fuel cells" promise huge range and power for eVTOLs|url=https://newatlas.com/aircraft/hypoint-turbo-air-cooled-fuel-cell-hydrogen-evtol-electric-aircraft/|access-date=2021-12-28|website=New Atlas|language=en-US}} There are also proposals to use batteries for takeoff/landing, and hydrogen fuel cells for cruising.{{Cite web|url=https://faculty.eng.umd.edu/sites/faculty.eng.umd.edu/files/NPD_JAHS2021.pdf|title=Hydrogen Fuel Cell and Battery Hybrid Architecture for Range Extension of Electric VTOL (eVTOL) Aircraft}}
