Design And Implement Architecture Of Distributed Digital Simulation Test Platform For Aircraft

In order to solve the problems of aircraft flight test environment construction and less evaluation of sub-samples and complete the new joint test pattern at platform level,such as attack-defense confrontation,operational test,simulation exercises.Range needs to use the simulation technology to build simulation test environment,to provide users with the flight simulation test platform of aircraft with such as flight environment,target feature,scheduling control,visual display,data storage,the interaction between system.In the paper,a distributed digital simulation test platform for the aircraft is designed and implemented.The techniques of real-time simulation,time unification,environment and target modeling and aircraft digital model verification are studied.It has completed the design of the system hierarchical structure,functional module division,interaction protocol design,workflow design and typical test scheme design.The platform can be compatible with the digital model of multi-model aircraft to complete the aircraft simulation tests,including statistical simulation,real-time simulation,launch process simulation,joint simulation,training simulation,etc.The simulation platform has been applied in the two aircraft test identification.The simulation results effectively supply the shortage of actual flight test sub-samples.The test consumption in aircraft identification is greatly reduced and increased coverage of the identification test.The reliability of aircraft technical performance evaluation is increased and the auxiliary evaluation task is completed well.The platform has completed the preliminary application in the simulation training and the attack-defense test,which enriches the joint simulation test pattern.
