Use of solar energy uavs air engineering 'take off' our reporter jiang LAN feiyun tianjiao

China aerospace science and industry group feiyun project has successfully completed the more vehicles autonomous flight validation, phased achievements. Feiyun engineering is the China aerospace science and industry group in recent years, introduced the 'five cloud' ( Feiyun, clouds, clouds, HongYun, clouds) Uavs, one of the main use of near space solar energy equipment, such as air LAN communication load, on the ground covered in communication. Alleged close space, it is 'empty' and 'day' of joints, photovoltaic (pv) grid, refers to the high from the ground area between 20 km to 100 km, in the traditional space between space and air space. At present, the solar energy, the field has become a great nation in the world competition strategy game and emerging strategic space. Near space solar drones powered by solar energy source, in the process of flying to get energy from the outside world, can be in near space flying a new type of platform for days or even months in a row, with high altitude, long life time, use convenient maintenance, and cost-effectiveness than higher characteristic, solar energy, solar energy, a sense has the characteristics of 'satellite', is a hotspot of current international research and development. China aerospace science and industry group, dean of the research and hong-wen zhang introduces, near space solar unmanned aerial vehicle (uav) innovative technology to reduce the difficulty of uav flight control, improve the performance in operation and maintenance; With lightweight, high strength composite airframe structure, enhance the wind resistance of unmanned aerial vehicle (uav) and environmental adaptability; By high energy power system and redundancy airborne equipment with high reliability, greatly improved the mission reliability of unmanned aerial vehicle (uav) long-endurance flight. 'Through coordinate matching design of each subsystem unmanned aerial vehicle (uav), with its high altitude, solar energy battery life long outstanding advantage, can be widely used in emergency communication support, remote sensing mapping, meteorological observation, and many other fields, has wide application prospect. 'Hong-wen zhang said. Hong-wen zhang introduces, feiyun uavs air LAN with solar energy engineering equipment, can provide greater than the ground base station network coverage and not subject to regional restrictions 'with type' network access services, to achieve regional user information connectivity, and for the user's IP data, voice, video and other business provides interface and transmission link; For remote mountainous area, such as small reef is difficult to set up base areas for effective communication network coverage solutions, at the same time can in a natural disaster area communication facilities damaged conditions, rapid recovery to communication skills. In addition, different coverage of unmanned aerial vehicle (uav) through the relay link information interaction between forming machine and machine, which can realize a wide range covered in network and communication.
