摘　　要：面向平行系统运行需求,对飞行器航迹计算的积分、抽象计算、数学模型等进行建模和架构设计,实现了航迹计算过程中数据与算法的分离,并采用继承和指针注册机制完成与航迹计算相关的数据统一化分层管理,通过对飞行器状态转移模型的设计实现了飞行器不同状态或阶段之间航迹的顺利衔接,能够实现多状态并行转移和执行,以抵消平行系统不确定性和随机性的影响,为平行系统运行提供灵活、高效的仿真模型。In this paper,a flight simulation model architecture is designed by combining the integration method,flight algorithm,external force calculation,earth model and other factors in flight simulation for the parallel system.This architecture realizes the separation of data and algorithm in the process of flight computation at the software level,and adopts inheritance and pointer registration mechanism to achieve unified and hierarchical management of data related to flight computation.The state transfer model of aircraft is designed to realize the smooth connection of flight states between different stages,which can realize efficient large-scale parallel computation.The architecture proposed in this paper provides a flexible and efficient interaction mechanism for aircraft agents.
