为了分析跑道坡度和风速分量对最大起飞重量的限制,以某型民用运输机为例,确定了不同特定情况下的修正跑道长度和跑道限制重量,通过线性回归分析得到了跑道坡度和风速分量对修正跑道长度和跑道限制重量的影响规律。研究表明:上坡时修正跑道长度和跑道限制重量均小于无坡度时的数值,且修正跑道长度和跑道限制重量均随坡度增大而线性减小,下坡时结论与上坡相反;上坡时修正跑道长度和跑道限制重量随坡度的变化率明显大于下坡时的情况;顺风对修正跑道长度和跑道限制重量的影响与上坡的影响类似,逆风则与下坡的影响类似。
In order to analyze the limitation of runway grade and wind speed component on the maximum take-off weight, take a civil transport plane as an example, determine the revised runway length and runway limit weight under different specific situations, and obtain the effect of runway slope and wind speed component on the correction Runway Length and Runway Limit Weight Impact Law. The results show that both the corrected runway length and the limited runway weight are smaller than those without slope, and both the corrected runway length and the runway limit weight decrease linearly with the increase of slope, while the downhill conclusion is opposite to the uphill slope. The effect of downwind on runway length and runway weight is similar to that on uphill, and upwind has a similar effect as downgrade.
