Study and test validation of turboshaft engine on-line performance monitoring technology

  • A model based on-line turboshaft engine(TSE) performance monitoring technology was studied, while an on-line TSE performance monitoring software was developed and subsequently applied to an actual TSE land rig test. Test results show that the software could automatically distinguish the working state of TSE on rig test. With use of the atmosphere pressure and temperature, gas turbine rotor speed and power turbine rotor speed, the software could calculate the TSE performance parameters such as compressor pressure ratio, power turbine inlet gas total temperature, output shaft power and specific fuel consumption et al. The calculation error of compressor pressure ratio between TSE model and the specific engine in rig test is less than 2.3%, which shows the significant performance difference between testing engine and baseline engine, and the effectiveness of the on-line TSE performance monitoring technology is confirmed.
