| 中文摘要: |
| 目的 研究涡轴发动机性能退化规律。方法 以某型涡轴发动机监控工作为基础， 根据该型发动机性能计算模型和发动机出厂时的排气温度基线， 计算稳定工作状态下该型涡轴发动机的排温裕度和燃油消耗率随工作时间的变化情况， 统计并分析近4～6年以来10台涡轴发动机的飞参数据。结果 随着工作时间的增加发动机的效率都会降低， 发动机的燃油消耗率随时间逐渐增大。结论 通过定期合理地清洗发动机， 及时采取防腐控制措施等方法， 可以减缓发动机性能的退化速度。 |

| Objective To investigate the performance deterioration regularity of turboshaft engine. Methods Base on the monitoring works of certain turboshaft engine, the performance calculation model was analyzed. The exhaust temperature margin and the fuel consumption during engine working were also determined based on the exhaust temperature baseline. The air data of ten turboshaft engines during the past 4 to 6 years was collected and analyzed. Results With the increase of working time, the efficiency of engines falls down. The fuel consumption rate of engines was gradually increased with time. Conclusion The performance deterioration speed of engines can be slowed down by regularly cleaning, in time corrosion protection and other methods. |
