The invention belongs to the technical field of helicopter design, and particularly relates to a helicopter longitudinal gravity center control method. The method comprises the following steps: acquiring characteristic data of a helicopter; determining a fuel oil combined weight G oil front and a gravity center C oil front in a front limit loading state; determining the combined weight G oil and the gravity center C oil of the fuel oil in the rear limit loading state; the minimum oil receiving value of the oil consumption delta G of the oil receiving tank at the beginning of transmission is determined; the maximum oil receiving value of the oil consumption delta G of the oil receiving tank at the beginning of transmission is determined; the oil transportation minimum value of the transfer oil transportation amount delta G is determined; determining the maximum oil transportation value of the transfer oil transportation quantity delta G; deltaG oil receiving and deltaG oil conveying are provided for the design of a fuel oil system, and the automatic transfer function is achieved.

    本发明属于直升机设计技术领域,尤其涉及一种直升机纵向重心控制方法。所述方法包括:获取直升机的特性数据;确定前极限装载状态的燃油合重量G油前、重心C油前;确定后极限装载状态的燃油合重量G油后、重心C油后;确定转输开始时受油箱的耗油量ΔG受油最小值;确定转输开始时受油箱的耗油量ΔG受油最大值;确定转输油量ΔG输油最小值;确定转输油量ΔG输油最大值;将ΔG受油、ΔG输油提供燃油系统设计,实现自动转输功能。
