基于最小成本的高度能力计算方法

考虑了风速对巡航马赫数的影响，研究了最小成本巡航马赫数和基于最小飞行成本的高度能力计算方法，分析了质量、温度与质心位置对高度能力的影响程度。结果表明质量对高度能力影响较大，温度只影响推力限制高度，质心位置只影响过载限制高度。高度计算结果与波音IN—FLT软件计算结果相比，在无风条件下误差不超过1％，该方法可行。

Altitude capability calculation methods based on minimum flight cost

Based on considing wind speed effect on cruise Mach number, the computational methods of cruise Mach number and altitude capability were proposed, the minimum flight cost was their objective function, and the effective extents of wind speed, mass, temperature on altitude capability were analysed. Analysis results show that the effective extent of mass on altitude capability is great, the effective extent of wind speed on thrust-limited altitude is great, the effective extent of certrobaric location on maneuvering capability limited altitude is great. The maximum error is less than 1% between the computational results by the methods and the computational results by INFLT software without wind, the methods are feasible. 4 tabs, 2 figs, 4 refs.
