摘要
针对放宽静稳定性(RSS)飞机,提出了一种一体化参数化设计与优化方法。首先,建立了放宽静稳定性飞机的数学模型,并重点考虑了七个主要设计参数;在设计中,引入了将适航飞行品质定性要求转化为定量指标的思路,量化了与操稳特性有关的部分适航条例;同时,还考虑了飞行控制系统对飞机设计的影响,将设计参数、适航指标以及飞行控制参数进行了综合优化;最后,运用多目标遗传算法进行了总体参数优化,并通过一个算例说明了设计方法的有效性。
A MDO approach to the conceptual design of commercial transport aircraft with relaxed static stability （ RSS ） was proposed. First, set up a mathematical model for RSS and consider seven major design parameters. In the design, the idea of quantitative requirements of airworthniess quality transformed into quantitative index is introduced. Second, part of airworthiness regulations related to operation stability is quantified. At the same time, the flight control-system design for RSS aircraft is also considered. Then, the multiobjective optimization of the design parameters, airworthiness criteria and flight control parameters are taken into account in order to achieve a better configuration. A calculation case study using typieal single aisle commercial transport aircraft demonstrates the effectiveness of the proposed MDO methodology.
