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。通过算例的数值计算和分析可知,改进算法不仅能完全符合法规要求,而且大大缩短了计算时间并提升和优化了起飞性能,为开发客户化性能分析软件提供了一种改进思路。
Under the framework of the standards of airworthiness regulation conforming to FAR25 and CCAR25, the performance calculation algorithm of commercial aircraft take-off midair is studied and an improved algorithm is proposed. The MATALB program was compiled by using variable step-length Runge-Kutta method, and the improved algorithm model was solved and compared with the current common algorithm. Through the numerical calculation and analysis of the example, it can be seen that the improved algorithm can not only fully comply with the regulatory requirements, but also greatly shorten the calculation time and improve and optimize the take-off performance, providing an improved idea for developing customized performance analysis software.
