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。 In order to relax the static stability (RSS) aircraft, an integrated parametric design and optimization method is proposed. First of all, the mathematical model to relax the static stability aircraft is established, and seven main design parameters are emphatically considered. In the design, the idea of ​​converting the qualitative requirements of airworthiness flight into the quantitative index is introduced, which is related to the stability characteristics At the same time, the influence of flight control system on aircraft design was also considered, and the design parameters, airworthiness indicators and flight control parameters were comprehensively optimized. Finally, the overall parameters were optimized by using multi-objective genetic algorithm An example illustrates the effectiveness of the design method.
