    摘要:

    基于模型的软件开发技术(Model-Based Development, 简称MBD)具有可视化建模与仿真、自动生成符合适航要求的代码等特点,已在民用飞机机载设备研发领域被逐渐推广应用。越来越多使用MBD技术开发的机载软件的涌现,给民机机载软件适航符合性工作带来了前所未有的挑战。为解决这一问题,美国航空无线电技术委员会于2011年底发布了DO-178C作为民用航空界认可的机载软件符合性方法,并在此基础上发布了DO-331作为专门针对机载软件MBD技术的适航符合性要求的补充说明。通过对DO-178C和DO-331标准中MBD软件适用目标的研究,结合工程实践,总结归纳了一套民用飞机主制造商对MBD软件供应商的软件研发过程管控要求,用于在向适航当局表明符合性时提高适航置信度,以期对主制造商和供应商在处理MBD软件方面提供参考。

    Abstract:

    Software model-based development technology has been widely used in civil aviation airborne equipment area because of its convenience of visual modeling and simulation, automatic code generation and so on. More and more airborne software developed by MBD technology has brought significant challenges to the airworthiness compliance of civil aircraft on software. In order to solve this problem, at the end of 2011, the American Aeronautical Radio Technical Committee issued DO-178C as an airborne software compliance method recognized by the civil aviation industry, and on this basis, it issued DO-331 as a supplement to the airworthiness compliance requirements of airborne software MBD technology. Based on the research of MBD objectives in DO-178C and DO-331 standards, combined with engineering practice, this paper summarizes a set of engineering monitoring process requirements of main civil aircraft manufacturers for using MBD technology to develop embedded software suppliers of airborne equipment, which helps to improve airworthiness confidence, so as to provide reference for main manufacturers and suppliers in processing MBD software.
