一种多任务仿真系统及其在过失速评估中的应用

Application of multi-task simulation system in post stall assessment

为研究新一代战机的过失速特性、作战效能和空战战法等不同需求,提出了能够灵活适应多任务需求的柔性仿真系统。基于敏捷仿真系统概念和框架,将仿真系统中的各模型单元设计为一系列自治的服务模型。通过描述契约定义可重用的仿真资源,亦即"服务",并可被机器处理。仿真系统被描述成系统层面上描述契约的组合。根据该开发方法实现多任务柔性仿真系统,支持研究飞行品质、空战战法和多机空战,并且易于扩展和适配后续变化的需求。利用该系统进行了战机过失速的作战效能评估,得出了最大迎角与捕获时间的定量关系。仿真结果表明,所开发的系统具有预期的仿真开发的快速适应性。

In order to research post stall characteristics,air-combat effectiveness and air combat tactics of the new generation fighters,a flexible simulation system is required to adapt to multi-task demand in this paper. Based on the concept and framework of agile simulation system,the model unit of the simulation system is designed as a series of autonomous service model. The reusable simulation resources are defined by description contracts,known as ＂ service＂,and can be machine-processing. The simulation system can be described as an abstract composition of description contracts. The development method is used to achieve the multi-task flexible simulation system,support the research of flying qualities,combat tactics and multi-aircraft air combat. The system is used to assess the closed-loop post-stall air-combat effectiveness,and the quantitative relationship between the maximum angle of attack and capture time is obtained. The results show that the system has expected rapid adaptability of the simulation development.
