Xinhua News Agency, Beijing, December 22Question: Multi-type domestic UAVs participate in emergency disaster response missionsXinhua News Agency reporters Hu Zhe and Song Chen.
Disaster reconnaissance, ground search and rescue, and emergency communication support ......Jishishan County, Linxia Prefecture, Gansu Province, occurred 6After Level 2**, China's multi-type UAVs quickly rushed to the disaster relief site and helped rescue and disaster relief through aviation technology.
At noon on December 19, the Pterodactyl-2H emergency disaster response UAV developed by the Aviation Industry Group was dispatched urgently to fly to the disaster area to carry out emergency communication support and disaster reconnaissance and other tasks. On the morning of the 20th, in order to further seize the rescue time, the Pterodactyl-2H emergency disaster response UAV carried reconnaissance and communication payloads, and once again flew from Sichuan Zigong Lantian Airport to Jishishan County, Gansu Province, to carry out emergency disaster reconnaissance and emergency communication support and other emergency disaster response tasks.

In the mission carried out on the 20th, the Pterodactyl-2H emergency disaster response UAV detected some house damage, infrastructure damage, road collapse, etc., and transmitted the real-time situation back to the command hall through high-definition pictures to realize image, voice, data up and down and visual command, so that the command center can grasp the on-site disaster situation in a timely manner, and make every effort to promote rescue and disaster relief and temporary resettlement.
At the same time, the Pterodactyl-2H emergency disaster response drone has been transformed into an "air base station" to continuously restore the smooth public network signal network of mobile, China Unicom and China Telecom in the mission area, achieving long-term and stable continuous public network signal coverage of about 50 square kilometers and providing communication support for the affected people.
The Pterodactyl-2H emergency disaster response UAV has the characteristics of long range, long endurance, large load, strong environmental adaptability, etc., and can fly normally in 8 to 10 winds, and complete tasks such as multi-spectrum disaster site reconnaissance, public network "three nets" and private network emergency network communication, and can restore 50 square kilometers of public network communication in a directional manner, and establish a voice communication network covering 15,000 square kilometers.

At the same time on the 20th, there was also a rainbow-4 emergency rescue drone that rushed to the rescue work in Jishishan County, Gansu Province. The aircraft gives full play to the advantages of long endurance, continuous reconnaissance and monitoring over the earthquake area, real-time transmission of image data, real-time linkage with ground rescue forces, guiding the ground search and rescue work in the earthquake area, successfully completing the 6-hour reconnaissance mission, helping relevant departments to grasp first-hand information and providing information support for the follow-up disaster relief work.
The Rainbow-4 UAV has a wingspan of 18 meters, a maximum ceiling of 7,200 meters, a maximum endurance of more than 30 hours, a maximum flight speed of 230 kilometers per hour, and a maximum take-off weight of 1,330 kilograms. In recent years, for different UAV application scenarios, Rainbow-4 has launched a new model equipped with heavy oil engine, which has good application capabilities in plateau and cold areas.
In order to meet a variety of needs, the Rainbow-4 UAV has a variety of configurations, such as satellite communication systems, high-definition photoelectric payloads, synthetic aperture radar, lidar, high-definition CCD cameras, hyperspectral cameras, communication relay equipment and other payloads, can perform a wide range of tasks in the civilian field, and has the characteristics of easy disassembly and assembly, sea, land and air transportation, etc., and can quickly complete the transfer deployment according to the needs of the mission.
