EHang AAV

Electric Passenger-grade Autonomous Aerial Vehicle
Superior to the traditional manned aircraft, the technology design concept of EHang AAV follows three philosophies: full redundancy to ensure security, autonomous pilot and centralized control of the intelligent command-and-control center. This eco-friendly and intelligent low-altitude passenger-grade autonomous aerial vehicle provides a low-altitude short-and-medium-haul transportation solution for the future intelligent transportation.

Autonomous Flight Real-time Network Connection
The technology of autonomous flight eliminates the possibility of failure or malfunction caused by man-made errors. Without any concern about controlling or operating the aircraft, the passengers can just sit and enjoy the journey. Flight routes will be surveyed in advance to preset multiple feasible plans for the user. EHang AAV uses 4G/5G as the high-speed wireless transmission channel to communication smoothly with the command-and-control center, thus enabling remote control of the aircraft and real-time transmission of flight data.

Visual Positioning For Vertical Takeoff & Landing
Traditional infrastructure such as large airport or runway is not required, suiting the scenario demands of urban air mobility and serving as an effective way to relieve the current traffic congestion pressures.

Electric Green Power
EHang AAV uses electric power to reduce environmental harm caused by emission. The aircraft can be fully charged in two hours. The charging devices can communicate in real time with the aircraft Battery Management System (BMS).

Safety Is Our First Priority
Redundancy design for all major flight components to ensure flight safety.

Hardware Safety
Redundancy design of backups for all major flight components. 

System Safety
Multiple flight control systems to enable data transmission and safe operation even in complicated situations. 

Flight Safety
Built-in Fail-Safe system in the flight control system to evaluate the health condition of the aircraft in real-time. 

Communication Safety
Double assurance of the communication system to avoid malicious interference. 

Contingency Reaction
In case of emergency, the command-and-control center will step in to ensure the safety of passenger and aircraft to the greatest extent.

Comprehensive Management by the Smart command-and-control Center
EHang command-and-control center is equipped with a set of intuitive AAV command-and-control system that provides the five core functions of monitoring, dispatching, controlling, early-warning and centralized management.

Safety Ensured by Redundancy Design and Fail-Safe System
The Fail-Safe safety system serves as a reliable guardian by equipping itself with multiple-redundant protection plans. The system can monitor each airborne device and acquire its operating status and health condition, and then transmit the information back to the command-and-control system. In case of any abnormal condition, a smoothest route will be selected and executed based on the preset algorithm logic to safely take the passenger to the destination.

Flight Testings and Quality Certification

Hundreds of testing subjects, including static test, load ground test, load flight test, durability test, reliability test,environmental test, anti-interference test, etc. under all kinds of inclement environments such as high/low temperature, high humidity, salt spray, typhoon, rainstorm. EHang has been granted with the certificate of AS9100D International Aerospace & Aviation Quality Management System Standard.
