    摘要:

    飞机地面除冰系统是保障冰雪天气民航飞行安全的重要装备,加热管是该系统的关键元件。为满足对高黏度除冰液的快速加热需求,提出一种新型双螺旋梯形槽管。建立以槽深h、上底宽m、底角θ为结构特征参数的异型管数学模型,采用多项式函数构建响应面近似模型,综合考虑结构参数对努塞尔数、阻力系数和综合评价指标的影响。利用非支配排序遗传算法进行多目标优化,筛选得到结构参数的Pareto最优解集。结果表明:当h∈[1.06,1.08]、m∈[0.17,0.33]和θ∈[84.06,84.75]时,努塞尔数提高了78.7%,综合评价指标提高了60%~62%。优化后的异型管可实现除冰液的快速加热,有利于提高航班正点率。

    Abstract:

    The aircraft ground deicing system is an important equipment to ensure civil aviation safety in snow weather. The heating tube is crucial component in this system. Double spiral trapezoidal grooved tube is proposed in order to improve heating efficiency of high viscosity deicing fluid. The groove depth (h), upper base width (m) and base angle (θ) were selected as structural characteristic parameters to establish the mathematical model of special tube. Polynomial function was adopted to construct response surface approximate model. The influences of structural parameters were analyzed on Nusselt number, flow resistance coefficient and the comprehensive evaluation index. The non-dominant sorting genetic algorithm II was employed in multi-objective optimization of special tube. The structural parameters of special tube were calculated by the Pareto solution set. The result indicates that Nusselt number improves 78.7% and the comprehensive evaluation index improves 60%~62% when h∈[1.06,1.08], m∈[0.17,0.33], θ∈[84.06,84.75]. The optimized special tube effectively achieves the rapid heating of deicing fluid,JP which is significant to promote the punctuality rate of flight in winter.
