Research On Synergies Of Orient-task Unmanned Aerial Vehicle/Manned Aircraft Hybrid Formation

Synergies between UAVs and manned aircrafts is an effective way to solve the current complex reconnaissance mission.The effect of synergies between unmanned aerial vehicles and manned aircraft on reconnaissance missions is affected by differences in load capacity,communication performance and decision-making mechanisms among hybrid formation members,and thus the evaluation of synergies performance of hybrid formation in uncertain environments becomes an urgent problem to be solved.On the basis of introducing the basic theory and method of evaluation,this thesis takes the information interaction as the starting point between unmanned aerial vehicles and manned aircraft,and takes the information in the gathering,transmission and decisionmaking dynamic cycle of the formation members combined with the characteristics of the reconnaissance task itself as the criterion of evaluation.The entity of the mixed formation members and the decision-making body are abstracted into three types of nodes,and the synergies performance of the hybrid formation is transformed into a hybrid formation logical network structure composed of three types of nodes.The formation of a group of reconnaissance tasks to complete the assessment of the extent and effectiveness of the problem,from the target recognition ability,network carrying capacity,network resilience,communication support capabilities and command and control capabilities of the five capabilities to build a hybrid formation synergies performance evaluation model indicators system,for the foundation of unmanned/ manned aircrafts hybrid formation synergies optimization problem.At the time of building optimization model of hybrid formation synergies performance,this thesis analyzes the factors network survivability index,uses the natural connectivity as the measure of the network survivability,which affects the reconnaissance efficiency.The constraints of the communication distance,the command system and the number of inter-office links are transformed into the constraint conditions,the optimization model of hybrid formation is established,and the algorithm is used to solve the model.The optimization results can effectively improve the synergies performance of the hybrid formation.The simulation experiment verifies the feasibility and applicability of the optimization model.The establishment of evaluation and optimization models of synergies performance between unmanned aerial vehicle and manned aircraft provides a new solution and implementation method for the research on synergies of orient-task unmanned aerial vehicle/manned aircraft hybrid formation.
