As a multiple tube system is considered to be usefiil to increase the power, a two-cylinder pulse detonation turbine engine (PDTE) is constructed to be investigated the system performance and turbine efficiency. The integrated system is consisted of a two pulse detonation combustor (PDC) exhausting through an automotive turbocharger and operated 100 Hz. As a result, a turbine expansion ratio, a turbine rotation speed and a turbine output by measuring enthalpy difference between in-outlet of the compressor of a turbocharger have been increased with increasing fill fraction. Comparing with two turbochargers which turbine diameter are different, turbine efficiency and turbine speed ratio U/C0 of Model Ahave been higher than that of Model B. The turbine efficiency of Model A has been increased with increasing corrected turbine rotation speed. When fill fraction is in the range from 0.8 to 0.85, the highest turbine efficiency has been attained.
