| Abstract: |
| 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. |
