Research on collision risk of large unmanned aerial vehicle operating in fusion airspace

With the rapid development of UAVs in recent years, UAVs are more widely used in all walks of life, and there is less discussion on the application of large UAVs. At present, the flight of large UAVs mainly relies on the joint operation of ground station operators and air traffic control systems, and is mainly based on experimental flights in non-converged airspace. Without reducing the acceptable level of safety, large UAVs enter the fusion airspace. Operation will be the inevitable development trend of airspace in the future. In this paper, the Reich model is improved. Based on the operation and error characteristics of large UAVs, a collision model between UAVs and manned aircraft is established. The existing Beijing-Shanghai route is selected for simulation, and the UAVs added to the existing airspace are calculated and compared. Before and after the collision risk, discuss and look forward to the feasibility of large UAVs entering the fusion airspace.
