Ehang 184 Austonomous Aerial Vehicle

EHang, a Chinese drone manufacturing company, has designed and developed the world’s first electric-powered autonomous aerial vehicle (AAV) named 184. It is a low-altitude drone that can carry a single passenger for 23 minutes of flight at sea level. It was introduced at the Consumer Electronics Show (CES) in January 2016.

The drone is designed for daily use and built entirely using new technology. Ehang plans to work closely with government agencies across the world to develop the 184 AAV and to formulate regulations for the future of transportation.

Design and features of the autonomous aerial vehicle

The EHang 184 is constructed using composite material with carbon fibre and epoxy, and aerial aluminium alloy. It flies in an inverted U-shape based on altitude and latitude of the origin and termination point.

The vehicle has four arms and occupies the same parking space as consumer cars when the arms are folded. It has an unfolded total span of 18ft (5.5m), and folded span of 5ft 3in (1.6m). The vehicle includes a trunk and the power system composed of four arms and eight propellers at the bottom.

The aircraft can take-off and land vertically eliminating the need for a runway. It has horizontal shaft distance of 2,422mm and vertical shaft distance of 2,388mm.

It is embedded with an EHang fail safe system that will make the aircraft land in the nearest possible area to ensure safety in the event of malfunction or disconnect of components. It also includes a downward-facing video camera.

The external dimensions of the vehicle include machine length of 3.86m, width of 3.89m, and a net height of 1.44m. The bottom clearance is 210mm and arm angle is 7.5°.

Flight control systems

The aircraft uses multiple independent flight control systems to guide passengers from point A to point B. The flight control systems are combined with real-time data collected by multiple sets of sensors throughout the flight. The real-time data will allow planning of the fastest and safest route.

The aircraft features an automatic navigation system, which doesn’t require a professional pilot. The communication system for the aircraft was designed to comply with a safety guarantee, as each vehicle comes with an independent key and every system is encrypted. The passenger can either choose to halt the flight or can hover in the air with just a single click in the event of an emergency.

Cabin details

"The aircraft features an automatic navigation system, which doesn’t require a professional pilot."

The EHang 184 AAV can accommodate a single passenger in the cabin. The cabin has height of 2,074mm and width of 1,018mm. It features two gull-wing doors for the entry and exit. The passenger seat is designed similarly to an F1 racing car seat. Passengers can easily input commands through a 12in control pad attached conveniently to the seat arm.

The cabin features a built-in air-conditioner that automatically adjusts the in-cabin temperature. It also includes 4G Wi-Fi internet, dual-colour reading light, four arm lights, signal light, headlight, and a 96V charging port.

Power and performance details

The 184 AAV is powered by eight motors, which generate maximum output power of 106KW. The aircraft is 100% electric and doesn’t depend on fossil fuels. The propeller has a length of 1,500mm.

The full battery consumption is 14.4kwh, and the battery charging time for trickle charge is four hours and two hours for fast charge.
The aircraft has an average cruising speed of 100km/h and can fly for 23 minutes of duration at sea level. It has a net weight of 200kg and can carry a load of up to 100kg. It is designed to fly at low-altitudes of less than 500m.
