| 摘 要： | 巡航速度是飞机重要的性能参数之一,波音等飞机制造公司的性能软件可以计算基于最小成本的巡航马赫数,但考虑的影响因素不全面。给出了最小成本巡航马赫数计算的通用方法,编制了FORTRAIN语言程序进行计算,分析了成本指数、风速、温度、质量等对经济巡航马赫数的影响。为制作最小成本飞行计划,降低航空公司飞行成本,提供了可靠的计算方法和分析依据。

| Abstract: | Cruise speed is one of essential performance parameters.Performance software of airplane manufacturing companies,like the Boeing Company may figure out the cruise Mach number based on the minimum flight cost.However,in view of the incomprehensive impact factors with the software,this paper offers a general calculation method for cruise Mach number based on the minimum cost,composes FORTRAN language program for calculation,and analyses the impact on economical cruise Mach number by cost index,wind speed,temperature and mass,which provides a reliable calculation method and analysis gist for composing flight plan with minimum cost and decreasing aviation cost resulted in higher economical benefit. |
