总体参数敏感性分析是确定客机总体参数的主要依据之一。以中短程客机作为背景机型,在开发了客机总体设计综合分析程序的基础上,首先应用优化方法确定出初步的总体参数,然后以此参数为基准点,着重分析总体参数对客机性能的影响,包括:机翼面积对质量和直接运营成本(DOC)的影响;组合参数(机翼面积与展弦比、机翼面积与后掠角)对质量的影响;发动机推力和机翼小翼的选装对起降性能和设计燃油质量的影响;组合参数(机翼面积与襟翼类型)对起降性能的影响;机身加长对起降性能和设计燃油质量的影响。最后将总体参数敏感性分析的结果以趋势图和地毯图的形式给出,可直观地洞察总体参数对性能指标的影响,为总体参数的调整和最终确定提供依据。

The determination of primary parameters in preliminary design is usually based on the sensitivity analysis of these parameters. This paper investigates the parameter sensitivity analysis for the preliminary design of a short/medium-haul airliner. A synthesis program for the preliminary design of civil jets is developed for use by the optimization and sensitivity analysis. The values of the primary parameters of the baseline design are found by optimization method. Based on the baseline design, the sensitivity analysis of primary parameters is investigated in detail, which includes the effects of wing areas on takeoff mass, fuel mass and direct operating costs (DOC), effects of multiple parameters (wing areas and aspect ratios, wing areas and sweep) on takeoff mass and fuel mass, effects of thrust of engines and winglet on the takeoff-landing performance and designed fuel mass, effects of wing area and flap types on the takeoff-landing performance, effects of fuselage stretch on the takeoff-landing performance and designed fuel mass. The results of the sensitivity analysis are presented in trend plots and carpet plots, from which the effects of primary parameters on the performances can be perceived directly. These results can guide designers to find more reasonable designs and make a final decision on the values of the primary parameters in preliminary design.
