Experimental investigation on the mixing chamber in pulse detonation chamber;

Pulse detonation engine has received much attention of late because of its several advantages compared to existent engines.

Using kerosene as fuel and air as oxidizer,two-phase detonation experiments were successfully conducted in two pulse detonation engine models with the diameters of 30 mm and 50 mm respectively.

Numerical investigation of multi-tube pulse detonation engine with common nozzle;

Exprimental investigation of integrating pulse detonation engine system;

Experimental investigation of air-breathing valveless pulse detonation engine;

Numerical simulation of the flow field of multicycle pulse detonation engine(PDE) is helpful for understanding the engine principle and performance analysis,and can provide the useful information for PDE design.

To improve the reliability of pressure measurement in detonation combustor of pulse detonation engine(PDE),the pressure/time curves of detonation were measured at single detonation and multicycle detonation,respectively,by using a dynamic pressure measurement system.

The results show that all nozzles can augment the thrust of baseline pulse detonation engine(PDE)and there is an optimal nozzle area ratio where thrust augmentation is maximized.

A new device system was developed to measure the pulsed temperature and vapor concen- tration in the exhaust flow during the multicycle process of pulsed detonation engine.

Based on a turbofan engine,the afterburner is replaced with pulse detonation combustor to form a turbofan-pulse detonation hybrid engine.

A hybrid pulse detonation engine principle test system which is make up of turbocharger,pulse detonation combustor,fuel supply cell,lubricant cell and measuring and control cell was designed and integrated.
