Research On The Architecture Of Trajectory Module For A Hla-based Sounding Rocket Simulation System

With the development of Computer Network Technology and Mathematical Simulation Technology,the simulation technique has been more and more widely applied to the Aerospace filed.The Simulation System of Sounding Rocket was proposed consequently.The Delivery System of Sounding Rocket which contains HLA and Mathematical Simulation Technology is the most significant part in the Simulation System of Sounding Rocket,its main function is to make use of the real-time calculation results to drive the flight process of launch vehicle in the scene.This thesis is concerned with several aspects of Delivery System Simulation of Sounding Rocket which are listed as follows:Firstly,the mission of the Simulation System of Sounding Rocket is analyzed and Six-Degrees-of-Freedom trajectory of Sounding Rocket in disturbance of wind field is modeled and simulated.At the same time,considering the affection of the wind,the technology of iteration and approach are used to revise the standard trajectory of Sounding Rocket.Secondly,several common simulation methods and the history of distributed simulation technologies are introduced;also,the thoughts and main characteristics of HLA,the three aspects composed of rules of HLA,interface specifications and OMT are discussed.Run-Time Infrastructure is introduced in the thesis.It is illustrated that HLA distributed simulation technology can meet the design requirements of the Simulation System of Sounding Rocket and has important value for application in the simulation of Sounding Rocket.At last,the characteristics of the simulation task of Sounding Rocket are studied emphatically,distributed simulation technology based on HLA is adopted,and the structure,interface and OMT of distributed simulation platform for small satellite formation flying are designed.The whole federation was divided into four federates including manager federate,interface federate,Sounding Rocket federate and observer federate.The structure and interface of every federate are designed and programmed to realize.The orbit module and the wind revision and compensation module are imbedded into the simulation platform.The extensible distributed simulation platform is realized which is suitable for kinds of Sounding Rocket,can verify the orbit of Sounding Rocket and make use of the wind revision.
