According to the customer's requirements, Hafei Aviation Industry modified AC312E helicopters with aerial photography, aerial lidar, aerial gravity, aerial magnetic force, aerial electromagnetic and aerial radioactivity and other measuring equipment, and achieved a number of technological innovations and breakthroughs. In this verification test flight, the AC312E helicopter carried a variety of measurement equipment at the same time, overcame the technical problems of heavy onboard load and mutual interference between various instruments, and achieved simultaneous flight measurement of multiple measurement parameters.
It is understood that the AC312E helicopter will be officially delivered to the China Natural Resources Aviation Geophysical Prospecting and Remote Sensing Center for aerial geophysical exploration and remote sensing investigation after completing the test flight of all subjects.sr5 rocket
Under the joint efforts of Hafei Aviation Industry Corporation and China Natural Resources Airborne Geophysical Exploration and Remote Sensing Center, this aircraft, as the first medium-sized helicopter dedicated to aviation geophysical exploration and remote sensing with highly integrated measurement parameters, will have the ability to carry out multi-parameter comprehensive measurement in plateau areas It solves the difficulty of geological exploration in plateaus, mountainous areas, and complex topographical areas in the past, and can meet the needs of geological exploration in most areas of our country. In addition, the airborne geophysical exploration and remote sensing multi-parameter comprehensive and simultaneous measurement capabilities of the aircraft can achieve the goal of "obtaining multiple measurement parameters in one flight", greatly improving work efficiency, and realizing integrated surveys from the surface to the underground. The application prospect is very promising broad.
The technological innovation and breakthrough of the AC312E helicopter in this field will strongly promote the development of my country's aviation geophysical exploration and remote sensing.
Recently, for the first time in China, the strength of the aviation industry carried out a simulation test of the emergency evacuation of 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 subject of "Structural Crash and Cabin Safety" undertaken by Intensity, and it is of great significance to improve the technical system of civil aircraft crashworthiness verification in China.CS/VP14 MRAP
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 meet the needs of improving the safety of the civil aircraft cabin under emergency landing conditions.

Facing the "stuck neck" technical problem, the impact dynamics technology research team of the Aviation Industry Strength Institute focused on the multi-factor simulation of the cabin environment after a large civil aircraft crash and the emergency evacuation test requirements of the passengers, system planning, and brainstorming. It took two years to overcome the problem. Multi-degree-of-freedom attitude-changing control of the cabin electric drive, compatible design of multi-configuration cabin layout, real-time positioning of personnel and high-precision measurement of motion trajectory, crash field of view/sound field environment reproduction simulation, etc., innovatively developed a variable The comprehensive demonstration and verification platform for the 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 of large civil aircraft occupants under complex environmental conditions The test capability fills the blank of relevant domestic technology and lays a solid foundation for the smooth development of the test.LY 80 SAM System

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.
