【摘要】 在符合FAR25部和CCAR25部适航法规标准框架下,对商用飞机起飞空中段性能计算算法进行了研究,提出一种改进算法。采用变步长Runge-Kutta法编制了MATALB程序求解改进算法模型,并与目前通用算法进行比较,通过数值计算和比较分析得到,改进算法不仅能完全符合法规要求,而且大大提升了计算时间和优化了起飞性能,为客户化性能分析软件开发提供思路。更多还原

【Abstract】 The algorithms of flare performance computation were studied based on the aviation law of part 25 of FAR and CCAR,and a new improvement algorithm was introduced.The variable step Runge-Kutta method is employed to the improvement model by MATLAB codes,and the same time compared with the common algorithm.The simulation results show that the improvement algorithm not only is full compliance with regulatory requirements,but also decreases the computation time and improves take-off performance.更多还原
