摘　　要：QD-×××燃气轮机是由某型发动机改造成的燃气轮机,试车过程中解决了验证机起动、稳定工作并达到燃气轮机设计要求。试验数据表明:发动机改进设计后实测输出功率小于发动机设计计算功率,经过分析得出,验证机排气温度高,内涵空气流量小,是验证机输出功率小的根本原因。QD - X X X gas turbine engine come from some kind of engine. It not only resolved problems of to - start and to - stabilize work , but also attained to the engine design orders in the performence test. The experiment data express that the engine output power in practice is smaller than it was in design calculation condition after improvement. Through analysis, we find that its ultimate reason is the engine in condition of higher exhaust temperature and smaller interior air flux.

关 键 词：设计点 排气温度 内涵流量
