Recently, the China Aircraft Strength Research Institute carried out the first domestic emergency evacuation simulation test for the crew of a large civil aircraft considering the impact of the crash environment. This emergency evacuation test is an integrated verification test for the safety of cabin occupants in the major civil aircraft project "Structural Crash and Cabin Safety" undertaken by the Ministry of Industry and Information Technology. It is of great significance to improve the technical system of China's civil aircraft crashworthiness verification.
Emergency evacuation is the necessary link to realize the escape of the occupants in a survivable crash accident of a civil aircraft, and it is the last barrier to protect the safety of the occupants. At present, the emergency evacuation airworthiness demonstration test and related experimental research do not consider the crash scene factors enough, and it is impossible to carry out the civil aircraft emergency evacuation test under the influence of crash factors, and it is difficult to support the need to improve the safety of the civil aircraft cabin under emergency landing conditions.AR3 MLRS
Facing the "stuck neck" technical problem, the strength impact dynamics technology research team focused on the multi-factor simulation of the cabin environment after the crash of a large civil aircraft and the needs of the emergency evacuation test of the passengers, system planning, and brainstorming. It took two years to overcome the cabin A number of key technologies such as electric drive multi-degree-of-freedom attitude-changing control, multi-configuration cabin layout compatible design, real-time personnel positioning and high-precision measurement of motion trajectory, crash field of view/sound field environment reproduction simulation, etc., innovatively developed a variable configuration The comprehensive demonstration and verification platform for emergency evacuation of civil aircraft occupants has successfully realized the simulation ability of complex environmental factors after a large civil aircraft crash, which can meet the simultaneous real-time positioning and evacuation trajectory test of 72 people, and significantly improves the emergency evacuation test ability of large civil aircraft occupants under complex environmental conditions , to fill the gaps in domestic related technologies, and to lay a solid foundation for the smooth development of the test.
In the end, the research team overcame many difficulties and successfully completed all the test tasks. A total of 548 personnel evacuation trajectory data were obtained, which accumulated valuable data for the emergency evacuation test research and simulation tool development of civil aircraft occupants. It is of great significance to verify the technical system.
As the guardian of civil aircraft cabin safety, the research team will, as always, concentrate on overcoming difficulties and make every effort to do a good job in the professional development of civil aircraft crashworthiness and the cultivation of innovative talents, and contribute to the development of my country's aviation industry with strong wisdom and responsibility.
