摘要
从飞机配平角度出发,讨论了飞机的平尾面积和重心后移量对飞机纵向气动导数的单一和综合影响,推导出了平尾面积与重心后移量之间的数学关系,提出了一种新的分析和计算相结合的方法来快速分析放宽纵向静稳定度飞机的平尾面积收益,并应用该方法分析了放宽伊尔-76飞机纵向静稳定度的平尾面积收益。
As viewed from the air craft＇s trimming angle, the effects of the quantity of rearward movement of the c. g. and the horizontal tail area on the craft＇s longitudinal aerodynamic coefficients are investigated respectively and synthetically, then the mathematical relation between the horizontal tail area and the quantity of rearward movement of c.g. is built. According to the results, a new method to analyze the horizontal tail area benefits for the RSS aircraft efficiently is proposed and applied to the tail area＇s benefits computation of IL-76.
