| Abstract: | The selection of an axial turbine or a radial turbine is a key problem for advanced micro-turbine engine with larger mass flow rate and power.A comparative research was completed to determine the suitable turbine form.For a micro-turbine engine of 12 centimeters diameter,one-dimension estimative model of axial turbine was established,and the output characteristic of axial turbine was analyzed.A micro axial turbine was designed,and the differences of power,efficiency,size and mass between the axial turbine a... |
