EHang (EHang Holdings Limited) is a company based in Guangzhou, China that develops and manufactures autonomous aerial vehicles (AAVs) and passenger AAVs[2][3] which have entered service in China for aerial cinematography, photography and survey missions.[4]

History

In January 2016, EHang announced[5][6] the Ehang 184, which was introduced at the Consumer Electronics Show in January 2016 as the world's first AAV capable of carrying passengers.[7][8]

The company announced plans with Dubai's Road & Transportation Agency in 2017 to launch an autonomous flying-taxi service starting in the summer of 2017,[9][10] though as of November 2017 there was no news about such a launch.[citation needed]

The company has also worked on a project with Nevada's Institute for Autonomous Systems for an AAV taxi that can transport a single passenger for up to 23 minutes with the EHang 184.[11]

In November 2018, an agreement was signed with the city of Lyon, France , to open a research center there. At the same time, a cooperation agreement was concluded with the Austrian aerospace group FACC to further develop, certify and produce for EHang in Europe as well.[12]

Aircraft

Ghost

Ghost is a quadcopter developed by Ehang in a typical quadrotor layout with a pair of skids as landing gear. However, Ghost has an unusual feature: the rotors are mounted below the tips of the arms, instead of being mounted on top of the tips of the arms like most other multirotors. Ghost is mainly intended for aerial photography missions, and it is controlled by a smartphone. Its complete name is Ghost Intelligent Aerial Robot (Chinese: Ghost智能空中机器人; pinyin: Ghost zhìnéng kōngzhōng jīqìrén).[13]

Hexacopter

Ehang Hexacopter is a UAV developed by Ehang and it has not yet been named. The existence of this hexacopter was revealed for the first time to the public when it made its public debut in August 2014 at TechCrunch Beijing.[15] The yet-to-be-named hexacopter is constructed of carbon fiber composite material with a pair of skids as landing gear. The arms of this hexacopter are curved, as opposed to the straight arms of most multi-rotors currently on the market. The hexacopter is controlled by laptop computer.[15]

The Ehang 184 is an autonomous, passenger drone capable of reaching over 62 mph (100 km/h). Ehang says it started carrying passengers in 2015 and since made 40 journeys till releasing footage in February 2018. In three years, more than 1,000 test flights were conducted, including some "violent" ones with dummies, in storm-force winds, in low visibility, at night and 1,000 ft (300 m) above the ground.[16] It has eight propellers on four arms and by July 2018, 30 to 40 single pilot EHang 184 have been built.[17]

General characteristics

  • Crew: None (self-piloted)
  • Capacity: 1 passenger
  • Length: 3.86 m (12 ft 8 in)
  • Wingspan: 5.5 m (18 ft 1 in)
  • Height: 1.44 m (4 ft 9 in)
  • Propellers: 8-bladed

Performance

  • Cruise speed: 130 km/h (81 mph, 70 kn)
  • Range: 16 km (9.9 mi, 8.6 nmi)
  • Service ceiling: 500 m (1,600 ft)

Ehang 216

The 216 is a two-seater with 16 propellers in a coaxial double-baled design. It has made over 1,000 manned flights by July 2018 and its maximum range flown was 8.8 km (5.5 miles).[17] It can fly 25 min for a range of 30–40 km (16–22 nmi). The aircraft is targeted for autonomous flying, to be monitored from an Ehang or its customer command-and-control center. Austrian aerostructures supplier FACC AG partnered with Ehang to certify and produce the aircraft in Europe, within simpler certification requirements for takeoff weights below 600 kg (1,320 lb).[20]

In October 2018, the CAAC approved initial passenger operations at specific locations to develop urban air taxis regulations. Ehang began taking preorders since, for island-hopping and to a Chinese coastal resort for aerial sightseeing within their site. A 1 km (0.54 nmi) shuttle across the river of its home city of Guangzhou should avoid a 30 min drive due to traffic congestion on the downtown bridge. US biotechnology company United Therapeutics, manufacturing organs for human transplants, should test rapid automated delivery from laboratory to hospital by the end of 2019.[20]
