An experiment on the outlet temperature distribution of an aero-engine reverse flow annular combustor was performed under several different working conditions.Outlet temperature distribution factor and radial temperature distribution factor were obtained.Temperature distribution along the height of turbine guide vane was studied in detail.A new concept called local sector radial temperature distribution along the height of turbine was proposed and it was recommended that when assessing the temperature factor it should be taken into consideration.The experiment results provide significant promotion for the evaluation and optimization of the outlet temperature distribution.
