The optimized rotor can evidently enhance the adiabatic efficiency and has fine off-design performance. 优化后叶片绝热效率有较大程度的提高，并且具有良好的变工况性能。
The highest adiabatic efficiency is increased by 7.4%and the stability operation margin also has a notable increase. 最高绝热效率提高了7.
The hot temperature difference and adiabatic efficiency increased by increasing cold air fraction,but cold temperature difference decreased. 冷流比增加
A multiobjective optimization for a two-stage axial-flow compressor design was performed for maximization of the overall adiabatic efficiency and the total pressure ratio. 针对一台两级轴流压气机,选定优化设计的目标是最大的总压比和最高的总绝热效率。
Calculation results illustrate that decreasing the blade hub-to-shroud loading level can increase the impeller adiabatic efficiency, and that aft-loaded impeller can obtain higher impeller adiabatic efficiency. 计算结果表明，在一定范围内，降低叶片轮缘－轮毂方向的负荷可以提高叶轮效率，后加载方式可以改善离心压气机叶轮性能。
