109 years ago today, on September 12, 1916 (August 15, 1916 in the lunar calendar), the world's first radio-operated unmanned aircraft was tested in the United States. On September 12, 1916, the first radio-operated unmanned aircraft was tested in the United States. Unmanned aircraft are also known as unmanned aerial vehicles, referred to as drones. The drone has a simple structure, low cost, and can complete a variety of tasks that manned aircraft are not suitable for. It has been widely used in the military. The functions and functions of drones are mainly as follows: ¢Ù As a target aircraft; ¢Ú Reconnaissance and surveillance; ¢Û Deception of enemy bait; ¢Ü Implementation of interference; ¢Ý Ground attack; ¢Ü Calibration; 0006 Communication relay. Israel's miniature drone solar-powered drone can be traced back to 1914. At the time of World War I, two British generals, Kadeer and Pitcher, made a proposal to the British Academy of Military Aviation: to develop a small airplane that could fly over the enemy without humans and be controlled by radio, so that it could drop bombs. This idea was supported by Sir Day Henderson, the director of the British Academy of Military Aviation at the time. The experiment was led by Professor A.M. Lowe. To keep it secret, the project was named "Project AT". After many experiments, the development team first developed a radio remote control device. The aircraft designer Geoffrey de Havilland designed a small upper monoplane. The development team installed a radio remote control device on the small airplane. 1914 The birth of the unmanned aircraft
