基于模型的民机适航要求自动捕获方法

 民机型号设计任务中包含的适航要求往往种类多、数量大，如果在型号研制初期不能准确、完整地捕获相关适航要求，将会造成后期因不满足相关适航要求而导致设计方案的更改和设计过程的反复。提出了一种基于模型的民机适航要求自动捕获方法，包括建立设计任务模型以形成对不同型号设计特征的统一表达，建立适航条款约束模型以支持对适航要求的语义描述，在建模基础上分析两者之间的映射规则，并开发相应的检索算法，以根据当前设计任务中包含的型号设计特征自动捕获其适用的适航条款要求。根据理论方法进行相应的软件实现，并通过飞机燃油系统设计特征实例检索过程验证了方法的可行性。

Model-based automatic capture of airworthiness requirements in civil aircraft design

Civil aircraft design must be carried out in accordance with a large amount of airworthiness requirements. Failure to capture proper requirements in early design stage may lead to unnecessary design iterations and solution alternations. Therefore, a model based method is proposed for automatically mapping proper airworthiness requirements to a current design task in the early design. It mainly includes a design task model for formal representation of different aircraft features, and an airworthiness constraint model for semantically representing airworthiness regulations. Based on the study of model mapping rules, a searching algorithm is also developed to facilitate requirements acquisition. Finally, a software tool is also implemented using the above method and tested through a case study.
