Research On USV Platform Design For UAV-USV Cooperation

With the rapid development of information acquisition and transmission technology,positioning and navigation technology,control technology and artificial intelligence,more and more unmanned platforms have been paid attention.This paper aims at the cooperative mission between UAV and USV at sea.Under the condition of limited offshore operation capacity of USV or UAV single platform,UAV is introduced into USV platform to construct UAV-USV collaborative mode,on the basis of the respective advantages and collaborative requirements of UAV platform and USV platform.The design of USV platform in UAV-USV cooperation is studied as follows:(1)Through the analysis of the development of USV related technology and mission requirements,this paper understands the development process of USV,and analyzes the key technologies in UAV-USV cooperation in view of the present situation and development trend of USV.Make clear the specific requirements of the collaborative model for the USV platform.Besides,the specific requirements of the collaborative model for the USV platform are made clear.(2)Through the performance analysis of the high performance vessel,the trimaran is selected as the ship type of the USV,the influence of the hull on the navigation performance is discussed,and the shape line of the trimaran USV oriented to coupled USV-UAV cooperative is determined.(3)Taking the resistance of trimaran USV as the research focus,the resistance division and resistance characteristics of USV are analyzed.According to the designed hull parameters and configurations,the CFD method is used to calculate the independent main body,side body and six kinds of configurations of trisomy ship in the range of Fr(28)0.15 ~ 0.75.The flight state analysis,resistance analysis and resistance interference analysis of the t trimaran USV are carried out.(4)This paper analyzes the influence of hull configuration on navigation performance and stability probes into the static water stability of trimaran USV,explores the floating state difference of hull configuration in waves,and finally studies the wave stability of each configuration.
