November 2, China’s self-developed C919 large passenger aircraft first machine officially offline, indicating that China can independently produce large passenger aircraft.

And the Lightning protection of the C919 domestic jumbo airliner is designed by the key laboratory of lightning protection of Hefei in Anhui Province, which is also the only large professional flying ⾏ Lightning Protection Laboratory in China at present.

C919 aircraft surface covering carbon fiber and resin composite materials, light weight, but poor conductivity, temperature resistance, Anhui Province aircraft Lightning Protection key Laboratory original Ray current rib technology, to solve the large-scale composite material lightning protection problems.

The Lightning protection system can prevent up to 200,000 of the current impact, only 0.5% of the natural lightning will be higher than this strength.

Anhui Province aircraft Lightning Protection key Laboratory was established in 1995, engaged in a variety of flying ⾏ line, including aircraft, helicopters, missiles, rockets, spacecraft and other fields of lightning and electrostatic protection research, to bear the Chinese aviation industry so far almost all military aircraft and most of the civil aircraft Lightning Protection test Research.

The laboratory uses the plate electrode to simulate the thundercloud, and the C919 Lightning Protection test is completed here.
