Semi-physical Deduction Platform And Simulation Study Of Carrier-based Aircraft Transportation

The dispatch and recovery capability of the carrier aircraft is the most important technical indicator to characterize the combat capability of the aircraft carrier,and it is the eternal theme in the construction and operation of the aircraft carrier in the future.Under the condition of limited resources such as deck space and dispatch time,optimizing the carrier-based scheduling strategy can improve the recovery efficiency of carrier-based aircraft and is of great significance to the improvement of aircraft carrier's operational effectiveness.As a simple,effective and intuitive simulation form,hardware-in-the-loop simulation has long been used for the command and dispatch of carrier aircraft carriers at home and abroad.This paper builds a semi-physical simulation platform based on the "Ford" class aircraft carrier which is used to support the research of key issues such as path tracking for aircraft carrier deck scheduling and analyzes the dynamic scheduling strategy of the carrier.The research contents are summarized as follows:Firstly,the design idea and implementation method of the semi-physical simulation for carrier aircraft automatic dispatching are introduced,including aircraft carrier flight deck model system,carrier aircraft model system,image-based model perception system and communication system.The construction of the platform is the basis for the research of carrier-based tracking control and path planning.Secondly,a path tracking control system based on decision system,model system of carrier aircraft and its perception system is constructed.The decision system includes a visual navigation algorithm and a steering controller,which can track the target path points of the carrier aircraft model in the simulation platform.The validity of the path tracking system is verified by tracking typical paths through experiments.Then,considering the constraints of deck environment,a path planning algorithm based on graph theory is proposed.The target path points are expressed in the form of network structure,and the fast path planning can be carried out according to the task requirements.The path planning is carried out for the main deck operation tasks such as carried aircraft dispatch and recovery,and combined with the simulation platform for deduction and verification.Finally,the service rules of each major carrier aircraft service station are analyzed in depth,and the linear service-oriented service model is introduced to mathematically express the service rules.The simulation model of high-intensity carrier aircraft trip recovery process based on the linear strategy is obtained.The accuracy of the simulation model is verified to be reliable,and the effects of two different scheduling strategies on the carrier rate and operational safety of the carrier aircraft are compared.
