Research On Overall Scheme Design Of Micro-miniature UAV Based On Swarming

Swarm UAV combines the swarm behavior of the animal with the micro UAV system.It integrates the advantages of large quantity,flexibility,distributed attack,anti-damage and low cost.With the deterioration of battlefield environment,the autonomous capability of UAV is constantly improving.A large number of micro UAVs with autonomous control ability can be used to form UAV swarm,which can be used to break through enemy defense system and carry out saturation attack on enemy targets,swarm UAV combat will become an important mode of UAV system application in the future.The main purpose of this paper is to develop the overall design technology of micro swarm UAV,and complete the overall design scheme of micro swarm UAV,including the overall parameter design,takeoff weight calculation,power plant selection,wing vertical tail design and so on.The aerodynamic characteristics of UAV are calculated and analyzed by CFD method.The aerodynamic layout of UAV is determined by aerodynamic analysis and comparison.The lift-drag characteristics of UAV are calculated.The longitudinal,lateral and heading static stability of UAV are analyzed.Then the motion modeling of UAV is completed,the formulas of aerodynamic force and aerodynamic moment are introduced,and the model of UAV system is established by using Simulink module of MATLAB software.The control characteristics of UAV's longitudinal and lateral motion are introduced.The control loops and control laws of UAV's climbing,sliding,flying and hovering are designed.According to the Simulink model and flight control law of UAV,the whole process of UAV's six degrees of freedom is simulated.
