摘要

可以用来提高轴式燃气涡轮发动机效率的方法之一是在以下两种配置中安装热交换器之一:低压涡轮后(一般情况);后高压涡轮(建议)。利用计算机程序分析了两种配置的理想循环和实际循环，其中研究了以下参数:热交换器效率、涡轮效率、压缩机效率、涡轮进口压力与压缩机输出压力之比(P3P2)和最高温度比(T3T1)。从两种配置的敏感性分析来看，在压气机和涡轮效率对总效率的相对影响以及涡轮进口压力对总热效率和功率输出的相对影响方面，异常配置不如建议配置。然而，通常的方法是优越的相对影响的压缩机和涡轮效率对功率输出。

Waste energy utilization in heat-exchange gas turbine cycles

One of the ways that can be used to increase the efficiency of a shaft gas turbine engine is by installing heat exchanger in one of the following two configurations:

1.
1. After the low pressure turbine (usual case);
2.
2. After the high pressure turbine (suggested).

Analysis of ideal cycles as well as a real cycle for both configurations is done by using a computer program, where the following parameters were studied: heat exchanger effectiveness, turbine efficiency, compressor efficiency, ratio of turbine inlet pressure to compressor delivery pressure ( $P_{3} P_{2}$ ), and maximum temperature ratio ( $T_{3} T_{1}$ ).

From the sensitivity analysis for both configurations the unusual configuration is inferior to the suggested in terms of the relative effects of compressor and turbine efficiencies on the overall efficiency and turbine inlet pressure on overall thermal efficiency and power output. However, the usual method is superior with respect to the relative effects of the compressor and turbine efficiencies on power output.
