TCab Tech was founded in May 2021 in Shanghai, China by Yon Huang Ng, CEO and other engineers. The company's goal is to make reliable and zero emission electric vertical takeoff and landing (eVTOL) aircraft for advanced air mobility (AAM) aerial ride-sharing for the general public. The meaning of TCab translates to "time taxi" which is the mission of the company to offer affordable and time-efficient air transportation to the general public. (Image credits: TCab Tech)
The company foresees using Artificial Intelligence to help their aircraft navigate through complex urban air space to ensure safety for all urban air travelers. The E20 passenger aircraft will be built in China and manufactured by the Shanghai TCab Technology Co., Ltd. After two rounds of funding earlier in 2021, the company raised nearly $10 million USD. Reported in February 2023, the company has had another funding round, raising 100 million yuan (approximately $14.8 million USD).
E20 long-range passenger eVTOL full scale prototype aircraft
The E20 is a long-range passenger eVTOL full scale prototype aircraft made specifically for advanced air mobility (AAM) and holds one pilot and carries four passengers. The aircraft has a futuristic design and has many safety features built into the aircraft. The E20 has no single point of failure in the flight control system and in the propulsion system. The main high wing allows passengers to enter and exit the aircraft with ease and safety and won't hit their heads on the propellers. In case of an all propeller failure during flight, the aircraft can glide and land on a road or runway like an airplane.
The aircraft has a cruise speed of 260 km/h (162 mph) and has maximum speed of 320 km/h (199 mph). The range of the aircraft is 200 km (125 miles) and has a maximum payload of 450 kg (992 lb). The cruise altitude is in the range of 300–600 m (984–1,969 ft). For propulsion, the aircraft uses four tilt-propellers for both vertical and forward flight and has two double stacked rotors for vertical take off and landing (VTOL) flight only. There are six electric motors on for the propellers powered by battery packs. The company expects as batteries improve over the years, the aircraft will be capable of being fully charged in a half hour.
The aircraft is made from carbon fiber composite for a high strength low weight ratio. Using this type of material is important for not only being to create the shape of the aircraft needed but to keep the weight low which increases the range of the aircraft. The windows are larger than conventional aircraft providing the passengers with a better views. The aircraft has one high wing and has a rear conventional tail. The aircraft has tricycle fixed wheeled landing gear.
2021
As of September 2021, according to one website, the population in China has reached 1.398 billion people and the company is counting on customers in China to use their aircraft in an effort to spend less time traveling to work and to gain more free personal time. TCab Tech and the entire aviation industry is aware that as low altitude restrictions become more lifted in China, the market for air taxi service should begin to boom.
TCab Tech announced on Monday, September 6, 2021 they had started flight testing, presumably with a sub-scale technology demonstrator as detailed by the company later in the year. Later in autumn, they announced that they had received 10 million dollars (USD) in investments in their seed funding phases. In December of the same year the company revealed a full-scale mock-up of the E20 along with planned vertiport infrastructure. Also in 2021, the company predicted their first commercial flight for the E20 will take place sometime in 2024.
2023
The company received a special flight permit and aircraft registration certificate from the Civil Aviation Administration of China (CAAC) in June 2023. After just four months of building the aircraft, the company successfully hovered, made the transition from vertical to forward flight and cruise flight. This took place at the Dongyang Hengdian General Airport in Zhejiang Province in China. The company has stated they've received more than 200 provisional orders for the E20 passenger eVTOL aircraft.
Future developments
The first market the company foresees to be successful with their E20 eVTOL aircraft will be in the tourism industry. TCab Tech expects its production aircraft to cost in the seven million yuan or approximately $960,900.00 USD. After that, TCab Tech expects their aircraft will be used in the on-demand urban air taxi industry.
