On Oct. 16, 2019, the Bristol, UK-based startup, Vertical Aerospace, Ltd., announced it had built and flown the world's first "electric air taxi capable of carrying 250kg [550 lb]". The prototype, named Seraph, completed its maiden flight at Llanbedr Airfield in Wales on August 22, 2019. As of October 2019, Vertical Aerospace has 70 employees and is actively hiring around 20 engineers, technical experts and operations personnel.

According to Vertical Aerospace's press release, Seraph follows the successful flight of Vertical Aerospace’s first full-scale Proof of Concept prototype in May 2018, the UK’s first electric Vertical Take-Off and Landing (eVTOL) aircraft to be granted flight permission by the Civil Aviation Authority (CAA). Vertical Aerospace says it "is working closely with global aviation regulators, including EASA, to achieve certification for commercial flight."

The company says that the Seraph was built to test new technologies and systems for integration into Vertical Aerospace’s upcoming passenger model, due to be unveiled next year. The aircraft can reach speeds of up to 80 km/h (50 mph). Vertical says that Seraph "features a unique passive cooling system and a customisable design, meaning the aircraft can be made larger or smaller, fitted with wheels or floats to facilitate water landings. With the Seraph, Vertical Aerospace’s team have developed concepts from their first aircraft and built in capabilities which will be critical for eVTOL aircraft seeking certification from aviation authorities."

Working closely with global aviation regulators, including EASA, Vertical Aerospace will begin with piloted air taxi services on city-to-city routes. Over time, as the technology and regulatory framework develops, it will expand the number of chartered routes served, introduce elements of autonomy, and ultimately, make completely on-demand air taxis a reality. The company has already begun the certification process for its next model, a passenger aircraft due to be unveiled next year.

For a timeline comparison of first flights, the company's first full-scale Proof of Concept eVTOL aircraft with four (4) propellers and which could hold up to four passengers, first flew indoors (tethered) on Aug. 25, 2017 at Cotswold Airport in Kemble, Gloucestershire, England. The same Proof of Concept's first unmanned free flight (untethered) took place on June 6, 2018 at the Cotswold Airport in Kemble.

The Seraph eVTOL full-scale prototype aircraft completed its first free unmanned flight at Llanbedr Airfield in Wales on August 22, 2019 and has flown over a dozen times up to October 2019. It could hold a pilot and two (2) passengers but this prototype eVTOL has no seats. The eVTOL aircraft has 12 propellers and 12 electric motors. Having more propellers provide more lift and redundancy for the aircraft. For example, if one or four propellers stopped working, the aircraft can continue to fly safely and make a safe emergency landing.

The Seraph eVTOL is made of lightweight carbon fiber which helps increase payload, range and allows it's design to be as aerodynamic per their engineer's requirements. It has a specialized cooling system using air from the propellers to cool its radiator system allowing the aircraft to fly in more types of weather conditions.

Today is another major milestone on the path towards carbon free flight. One year ago, we flew a full scale electric VTOL aircraft, the UK’s first.

Today, we’re revealing flight footage of our second full scale prototype, the Seraph, an air taxi prototype capable of carrying 250kg. Air travel is one of the worst contributors to climate change and among the slowest sectors to decarbonise. Our mission at Vertical Aerospace is to make personal, on demand and carbon free flight a reality.

The purpose of the Seraph eVTOL is to test and understand how all components and software work in the real world allowing the company to use this knowledge and apply it to their upcoming passenger model, which is expected to fly in the second half of 2020 and will look substantially different than the Seraph. The next model is planned to be the first production model and will include a pilot, passengers, wings and room for luggage. The company completed preliminary design review in late January 2020.

The next passenger eVTOL's capacity will allow one (1) pilot and four (4) passengers, use fly-by-wire technology, have a composite fuselage, and allow customization of the landing gear allowing the purchase of either skids, wheels or flotation landing gear as required by the customer.

Vertical Aerospace also announced in October 2019 the acquisition of MGI Technologies, a Formula 1 an engineering design, R&D, and production company which can design and rapid-build in-house accurate lightweight composite fuselages, including crash and fatigue analysis, aerodynamics testing and much more.

We have long believed that the technologies and approaches from Formula 1 could be applied to a range of engineering challenges. Vertical Aerospace’s vision provides a fantastic outlet for our experience and a unique opportunity to shape the future of flight.

— Mike Gascoyne, CTO of Vertical Advanced Engineering , Vertical Aerospace press release, Oct. 17, 2019

This acquisition allows Vertical Aerospace to take a different approach to designing and building eVTOL urban aircraft. While mainstream aircraft manufactures might take a 5 to 10 year lead time to go from a clean-sheet design to a production aircraft, the MGI team can work at an extreme fast and high quality pace which you normally don't see in the aerospace industry.

For example, the company makes new Formula 1 race cars each year and they see what works and what doesn't and then move forward with the best design possible for the client. MGI Technologies has a history of working with the motorsport industry, aerospace industry, automotive industry and the marine industry. They are highly qualified engineers and specialists who will bring a fresh look and designs while working together along with the entire Vertical Aerospace team, to create the best eVTOL aircraft that current technology allows.

The company was founded in 2016 by CEO Stephen Fitzpatrick, founder and CEO of London-based OVO Energy. Vertical Aerospace is current working on how to scale up from making prototypes to designing and building a manufacturing line. The current plan is to focus on being an eVTOL manufacturing company and at this time are not planning to operate an air taxi business. According to the company, "Vertical Aerospace is building technology to revolutionize how people fly, with the ultimate aim of making intercity air travel personal, on-demand and carbon free."
