Founded in May 2008, the Commercial Aircraft Corporation of China, Ltd. (COMAC) is a Chinese state-owned aerospace manufacturer established headquartered in Shanghai, China. According to one source online, the company has a registered capital of RMB 19 billion ($2.7 billion USD as of May 2008). The corporation designs and manufacturers three different large jetliners, named the ARJ21 Xiangfeng, C919 and the CR929. The largest jetliner the company proposes to make is currently called the C939.

CE4VT passenger eVTOL concept design aircraft
The CE4VT is a new passenger eVTOL concept design aircraft designed by the Beijing Aircraft Technology Research Institute. This is a long-range aircraft for advanced air mobility (AAM). The aircraft holds one pilot, three passengers and their luggage. The concept design has large panoramic wrap around windows allowing forward, left and right visibility for spectacular views for the pilot and passengers. The eVTOL has been designed very similar to a conventional aircraft which will make the certification that much easier for China's government regulators and those regulatory departments of other nations.

Most of the specifications are unknown at this time. The aircraft has eight propellers located on four booms under the main high wing and the aircraft is powered by battery packs. The front propellers are most likely tiltprops and the rear four propellers are VTOL only propellers. The approximate maximum payload weight of the aircraft is ~450 kg (~992 lb). The fuselage is made from carbon fiber composite for a high strength to low weight ratio. In the rear of the aircraft is boom tail. The aircraft has fixed tricycle wheeled landing gear.

The safety features includes Distributed Electric Propulsion (DEP) uses multiple propellers, each powered by electric motors, to increase safety for the aircraft through redundancy. If one or more components fail, the remaining ones can still ensure a safe landing. There are also redundancies of critical components in the sub-systems of the aircraft providing safety through redundancy. Having multiple redundant systems on any aircraft decreases having any single point of failure. The aircraft can land conventionally in case there is multiple propeller failures.

  • Safety features: Distributed Electric Propulsion (DEP) uses multiple propellers or electric ducted fans, each powered by electric motors, to increase safety through redundancy. If one or more components fail, the remaining ones can still ensure a safe landing. There are also redundancies of critical components in the sub-systems of the aircraft providing safety through redundancy. Having multiple redundant systems on any aircraft decreases having any single point of failure.
