The reporter recently learned from the Third Academy of China Aerospace Science and Industry Corporation that the institute proposed to build a flying cloud project based on solar drones in the near space to build an airborne LAN, which can achieve long-term communication guarantees for ground and sea users. Up to now, Feiyun Engineering has successfully completed multiple autonomous flight verifications, successfully carried out communication application verification based on space-based platforms, and achieved initial results.
Proximity space solar drones are a new type of platform that uses solar energy as a source of power, autonomously obtains energy from the outside during flight, and can fly continuously for days or even months; the flight altitude can reach the proximity space, with high flight altitude and long battery life. The characteristics of long-term, easy to use and maintain, and so on have a "quasi-satellite" feature in a certain sense, which is the focus of current international research.
It is reported that the solar drones developed by the Third Academy of Aerospace Science and Technology have achieved high lift-to-drag ratio aerodynamic performance while reducing the difficulty of drone flight control. The use of ultra-light high-strength composite material body structure has improved the wind resistance and Environmental adaptability and the use of high-efficiency energy power systems have greatly improved the mission reliability of UAV long-endurance flight.
"Through the matching and coordinated design of various subsystems, solar drones can be widely used in emergency communications support, remote sensing surveying, meteorological detection and other fields due to their outstanding advantages of high flying height and long battery life, and have broad application prospects. Said Zhang Hongwen, president of the Third Academy of China Aerospace Science and Industry Corporation.
Zhang Hongwen introduced that the Feiyun project uses solar drones to carry air LAN communication equipment, which can provide network coverage that is much larger than ground base stations and "companion" network access services that are not restricted by regions, and realize the interconnection of user information in the region. It also provides transmission links for users' IP data, voice, video and other business data; it can provide effective communication network coverage solutions for areas where it is difficult to set up base stations, and at the same time under the conditions of natural disasters and damage to regional communication facilities, Quickly restore communication capabilities in disaster areas.
