In a world first, Chinese researchers have flight-tested new streamlined thrust technology in a high-speed drone, capping nearly two decades of research in the area for the lead scientist. The lighter and simpler aerodynamic thrust vectoring system abandons the complex mechanical parts of elite fighter jets like the F-35B and Su-37 to redirect engine exhaust to make the aircraft more manoeuverable. Nanjing University of Aeronautics and Astronautics announced last month that a team led by...
