| 为获得机载系统轴功提取和引气一体化管控对发动机燃油经济性的影响机制，建立实现该功能的自适应动力与热管理
系统模型，利用4 阶龙格库塔法与牛顿迭代法耦合求解，分析了不同巡航高度H 下轴功提取与引气能量转换效率比浊、轴功提取与
引气作功比姿、APTMS 相对转速Nz 等对系统燃油代偿损失的影响。仿真结果表明：轴功提取与引气能量转换效率比浊大于临界值
时，系统燃油代偿损失随着轴功提取与引气作功比姿的增大而减小，反之则燃油代偿损失增大，变化幅度最大可达20%；APTMS 相
对转速Nz 越大，半闭式空气循环风扇涵道引气越小，动力涡轮低压级引气及功率提取量越大，则燃油代偿损失越大，增量最大可达
1 倍。说明通过轴功提取与引气一体化管控可有效提高发动机燃油经济性。 |

| In order to obtain the influence mechanism of shaft power extraction and air intake integrated control on engine fuel
economy，an adaptive power and thermal management system （APTMS）model to realize this function was established. By using the coupling
solution of fourth order Rungokutta method and New-Raphson iteration method，the effects of shaft power extraction and air intake energy
conversion efficiency ratio η，shaft power extraction and air intake power ratio λ，APTMS relative speed Nz on the fuel compensation loss of
the system were analyzed under different cruising altitude H. The simulation results show that when the shaft power extraction and air intake
energy conversion efficiency ratio ηis greater than the critical value，the fuel compensation loss of the system decreases with the increase of
shaft power extraction and air intake power ratio λ，on the contrary，the fuel compensation loss increases，and the maximum variation range
is 20%. The larger the relative rotation speed Nz of the APTMS，the smaller the air intake of the half-closed air circulation fan，the higher the
air intake and power extraction of the low-pressure stage of the power turbine，and the larger the compensation loss of the fue，the maximum
increment can be up to 1-fold. It is described that the fuel economy of the engine can be effectively improved through the integration control
of the shaft power extraction and air intake. |
