    摘要:

    为提高我国民用飞机实现主动重心控制功能的技术成熟度和工程实现的安全性,以主动重心控制功能原理为基础,参考国外典型飞机的设计方式,提出了主动重心控制功能应具备人工和自动两种控制方式,在一定的安全高度和系统状态条件下启动,并同时具有前向转输和后向转输的功能逻辑设计原则。在工程实现层面,构建了主动重心控制功能的系统架构,分析了典型飞机对座舱控制面板设计和显示告警等方面的考虑。在关键技术层面,分析了工程实现中可能遇到的燃油测量误差、飞机重心超限和控制器故障等问题,并提出了通过设置目标重心阈值和重心调节阈值、采用非相似的实时重心解算监控和允许重启并重新输入当前飞机重量重心等解决措施。相关结论可为我国民用飞机主动重心控制功能的工程设计提供参考。

    Abstract:

    To improve the technical maturity and engineering realization safety of the active center of gravity control function of civil aircraft in China, based on the principle of active center of gravity control function and referring to the design methods of typical foreign aircraft, it is proposed that the active center of gravity control function should have two control modes, manual control and automatic control, which can be started at a certain safety height and system state conditions, and it has the functional logic design principle of forward transfer and backward transfer separately. For the engineering realization, the system architecture of the active center of gravity control function was constructed, and the considerations of the design of the cockpit control panel and display alarms of a typical aircraft were analyzed. For the key technologies, the possible problems of fuel measurement errors, aircraft center of gravity overruns and controller failures that may be encountered in engineering implementation were analyzed, and the solutions were proposed by setting target center of gravity thresholds and center of gravity adjustment thresholds, using non-similar real-time center of gravity solution monitoring and allowing restart and re-enter of the current aircraft weight center of gravity. The relevant conclusions can provide references for the engineering design and realization of active center of gravity control function of civil aircraft in China.
