EHang 184 (defunct)


EHang 184 (defunct)
Guangzhou, China

EHang was founded in December 2014 by Huazhi Hu, Chairman and Chief Executive Officer and Derrick Yifang Xiong, Director and Chief Marketing Officer. EHang is an autonomous aerial vehicle technology platform company based in China and is pioneering the future of all-electric aerial transportation through multiple proprietary products and services. The company designs and manufactures electric vertical takeoff and landing (eVTOL) passenger and cargo aircraft for advanced air mobility (AAM). The mission of EHang is to provide safe, autonomous and eco-friendly air mobility for everyone. The designation of its EHang 184 single-seat eVTOL means “1 passenger, 8 propellers, 4 arms.”

EHang's proprietary electric products and services include:

  • eVTOL passenger transportation
  • eVTOL logistics
  • Smart city management
  • Command and Control Center (For passenger, cargo and drone services.)
  • Multiple commercial eVTOL drone services (Such as aerial mapping; forest fire surveillance, inspection and reporting; public safety surveillance; traffic management; 3 dimension modeling; news reporting and more.)
  • eVTOL Aerial Media (Light shows in the sky at night created by using thousands of drones.

EHang 184 autonomous passenger eVTOL prototype multicopter aircraft
The EHang 184 is an autonomous one passenger eVTOL prototype multicopter (now defunct) Autonomous Aerial Vehicle (“AAV”). The aircraft was designed by the founder and CEO, Mr. HU Huazhi. In late 2012, Huazhi started to design the initial verification model. Manned and unmanned flight testing has been conducted in China in 2015-2017, USA (Nevada) in 2016-2017 and UAE (Dubai) in 2017.

The aircraft has a cruise speed of 100 km/h (62 mph). The EHang 184 has eight propellers, eight electric motors and is powered by batteries. There are no propeller guards on the aircraft. The power of the electric motors is 8 x 152 kW (8 x 200 hp). The empty weight of the aircraft is 260 kg (573 lb), has a maximum payload of100 kg (220 lb) and has a maximum takeoff weight of 360 kg (795 lb).

The fuselage is made from of carbon fiber composite for high strength to low weight ratio. The aircraft has a canopy over the cockpit and has windows in both doors. The fuselage length is 4 m (13 ft), its overall height is 1.4 m (4.6 ft) and has a wingspan of 4 m (13 ft). The tip-to-tip distance of the aircraft is 5 m (16.4 ft). The aircraft has fixed skid landing gear.

Additional information about the company and other aircraft models
In a July 2017 interview for CNBC, EHang co-founder Derrick Xiong stated that “at this moment we are working closely with Dubai and we have actually, together with them, have done numerous tests internally. Also, we have basically done a lot of — many, many times — tests with a passenger on it, including the vice-mayor of Guangzhou City in China and also some governors from Dubai as well. We have done a lot of tests and we aim to do the very first public demo very soon this year.”

In Feb. 2018, EHang unveiled that it had made a new version, apparently with two-seats named the “EHang 216” that has twice as many arms. The company also reported that the “EHang 184 AAV achieves a series of manned flight tests with up to 40 persons,” including the EHang CEO onboard.

It was reported in January 2020, that the EHang 184 was retired and replaced with the EHang 116. The two production models are the EHang 116 (1 passenger aircraft) and the EHang 216 (2 passenger aircraft).

Specifications (Feb. 2017):

  • Aircraft type: eVTOL passenger prototype multicopter aircraft
  • Piloting: Autonomous
  • Capacity: 1 passenger
  • Cruise speed: 100 km/h (62 mph)
  • Empty weight: 260 kg (573 lb)
  • Maximum payload: 100 kg (220 lb)
  • Maximum takeoff weight: 360 kg (795 lb)
  • Propellers: 8 propellers
  • Electric motors: 8 electric motors, 8 x 152 kW (8 x 200 hp)
  • Power source: Batteries
  • Fuselage: Carbon fiber composite
  • Fuselage length: 4 m (13 ft)
  • Overall height: 1.4 m (4.6 ft)
  • Wingspan: 4 m (13 ft)
  • Tip-to-tip distance: 5 m (16.4 ft)
  • Window: Canopy over cockpit and side windows
  • Landing gear: Fixed skid landing gear
  • Safety features: Distributed Electric Propulsion (DEP), provides safety through redundancy for its passengers and/or cargo. DEP means having multiple propellers (or ducted fans) and motors on the aircraft so if one or more propellers (ducted fans) or motors fail, the other working propellers (or ducted fans) and motors can safely land the aircraft. There are also redundancies of critical components in the sub-systems of the aircraft.
