Research On The Minimum Safety Distance Based On CNS Performance Under The Mixed Operation Of UAV And Manned Aircraft

At present,UAVs are developing rapidly and iteratively.In the fourth wave of industrial revolution dominated by new technological revolution such as artificial intelligence,UAV has become an important carrier of advanced productivity.With the promotion and application in general and transportation aviation fields such as aerial photography,plant protection,logistics,surveying and mapping,patrol inspection,security,UAV is gradually integrated into the national airspace system.This process has brought unprecedented opportunities for China’s civil aviation to transform from a big one to a strong one and to "change lanes and overtake".With the increasing application range of UAVs and the increasing demand for airspace resources,UAVs urgently need to share non-segregated airspace resources with manned aircraft.To accelerate the integration of UAVs into the national airspace system and promote the development of aviation industry.In this thesis,the safety distance between unmanned aerial vehicle(UAV)and manned aerial vehicle(UAV)is studied.Starting with the performance of CNS,the impact of CNS on the collision probability of UAV and UAV in mixed operation is analyzed.At the same time,other factors affecting the aircraft positioning error are analyzed,including anti-collision equipment,human factors,meteorological conditions,etc.Using the simulation experiment,the visual graph of the influence of various factors on the positioning error in a certain time is obtained.Combined with the Event collision risk model,a new collision risk model based on CNS performance is calculated according to the characteristics of UAV and UAV operation and the target safety level(TSL)specified by the Civil Aviation Administration.Considering other influencing factors,the collision risk model of CNS performance is improved,and the minimum safe distance calculation model combining other influencing factors is obtained.After that,the simulation experiment is carried out by python,and the calculation is carried out by substituting the aircraft example.According to the calculation results,the influence of CNS performance on the safety distance of UAV and UAV in mixed operation is analyzed,and the minimum safety distance is calculated.
