Abstract

To explore the feasibility of pulse detonation-turbofan combined engine(PDTE)

a whole test system of kerosene/air triple-tube aero-valve pulse detonation engine(PDE) was established.Aconverging nozzle and a converging-diverging nozzle were designed.Within detonation tube of 100 mm in inner diameter and 2000 mm in length

triple-tube PDEcould be operated at 30 Hz in total frequency

and the fully-developed detonation waves were successfully achieved.The effect of interaction among detonation tubes on detonation combustion properties of triple-tube pulse detonation engine was investigated.Because the detonation pressure in tube of triple-tube PDEwith common nozzle was raised

the performance of triple-tube pulse detonation engine was improved.The results lay a basis for preliminary design of practical multi-tube pulse detonation engine.
