Experimental investigations of interaction of a pulse detonation combustor with a turbine

Experimental investigations of a principle model of interaction of pulse detonation combustor(PDC) with turbine were made by using gasoline and air as fuel and oxidizer.The experimental results show that pulse detonation combustor can run stably.During PDC detonating,the air mass flow at the compressor outlet is about 100 kg/h more than that of PDC required for detonation.The full pulse detonation is achieved before the PDC outlet.The peak pressure and wave speed of pressure wave are significantly reduced after expansion through the turbine.Larger fill fraction can lead to a stronger detonation wave and a strong shock wave can be less affected by an obstacle like a turbine than a weak one.The turbocharger does not exhibit any signs of damage after over 40 minutes of detonation testing.
