摘要
将放宽静稳定性与飞机的经济性指标直接关联,研究主要设计参数对飞机气动性能和直接使用成本的影响。首先分析了静稳定性设计对民机气动性能、结构质量及燃油消耗的影响;然后与民机使用经济性相结合,得出重心后移量与直接使用成本的函数关系和曲线。结果显示,采用放宽静稳定性技术有助于提高民用飞机的使用经济性。该研究方法可以为我国大型客机采用主动技术提供技术依据。
In this paper,the effects of the main design parameters on the aerodynamic performance and direct operating cost（DOC） of aircraft are studied by correlating the relaxed static stability（RSS） to the economic indexes of the civil aircraft.Firstly,the effects of RSS on the civil aircraft aerodynamic performance,structural quality and fuel consumption are analyzed.Then,combining RSS with DOC,the functional relationship between the gravity center shift and DOC is established.The results show that RSS contributes to improve the economics of the civil aircraft.The research method can provide useful reference for the application of the active control technology on the large transport jet aircraft.
