开放式飞机总体设计环境的原型研究

Prototype System Research on Open Conceptual Aircraft Design

为综合集成飞机总体设计过程中所使用的各种设计分析工具以更大程度地发掘软件资源的技术价值、提高设计质量和设计效率,提出了采用开放式系统进行资源整合的方法。分析了飞机总体设计中软件应用所存在的问题及典型集成系统发展现状,定义了飞机总体设计中的模块、组件、子系统等功能实体单元及开放式系统架构的概念,并以此为基础设计了包含资源层、中间层、应用层和协同层4个层次的系统软件架构以及构建于网络之上的系统硬件架构体系。规划了系统集成与数据传输逻辑,提出了采用智能体进行飞机总体设计分析工具集成的途径,完成了包括组件自定义开发、方案设计和任务管理在内的各子系统构建逻辑并实现其正常运转。最后给出了基于系统开放式架构所形成的战斗飞机总体设计环境以说明系统集成的可行性及应用前景。

This article proposes an approach of building a system with an open framework for aircraft conceptual design.This approach is able to make better use of current tools and improve design quality and efficiency by integrating many tools applied in the conceptual design process.Some issues on software application during the aircraft conceptual design process are analyzed.The definitions of function units and open framework used in the design process are stated.The system software framework,including the resource tier,service tier,application tier and cooperation tier,and the hardware framework built on network are designed.The logic of system integration and data transmission are laid out.The approach of using agents to integrated analysis tools is brought forward.Subsystems of customized component development,concept design and solution management are established and operated successfully.A fighter conceptual design environment based on the open framework is finally outlined to illustrate the feasibility and application prospects of the system.
