Energy Consumption Modelling of Coaxial-Rotor in Vortex Ring State for Controllable High-speed Descending

The ability to fast climb and descend is crucial for Unmanned Aerial Vehicle (UAV) applications in the mountains. The slower descent speed will affect the UAV’s working efficiency in reaching the rescue area. However, during the fast descent of the rotorcraft, a chaotic flow field rampages as the ro…
