Abstract

For the characteristics of low speed and low expansion ratio for axial flow power turbine, the test bench was built by using the loading compressor as the power consuming component and the adiabatic efficiency characteristics of axial flow power turbine was then corrected with the temperature drop method. The similarity processing for design parameters of power turbine were conducted according to the similar principle during the test and the measurement was carried out by driving the power turbine with the low temperature gas below 80 ℃.In order to improve the test accuracy, some measures such as electric heating, pipeline wrapping and exit pressure fluctuation treatment were adopted. The test results show that the adopted technical measures can meet the test requirements of axial flow power turbine adiabatic efficiency characteristics.
