One of the current strategies employed for enhancing the deflagration-to-detonation transition (DDT) process in pulse detonation engines (PDEs) is the employment of bluff-body obstacles. The combustion process is enhanced by the presence of the obstacles due to the turbulence created as the flame-induced flow interacts with the obstacle structure, in addition to possible shock-wave structure ... [Show full abstract] interactions. Although optimized obstacles will provide a net gain in thrust due to the promotion of earlier transition to detonation, there will be a penalty due to the form drag associated with the obstacles. Recent studies on steady-flow premixed combustion systems have demonstrated the capability of using fluidics to provide a "virtual" bluff body for flame stabilization. Several benefits have been observed through the employment of the fluidics in terms of combustion rate enhancement, reduced total pressure losses, and diminished receptivity to thermo-acoustic oscillations. The current paper describes research conducted at the Air Force Research Laboratory's Pulse Detonation Research Facility (PDRF) that is an extension of this approach for enhancement of unsteady combustion processes such as that found in pulse detonation engines. The ability to manipulate the flame speed and post flame combustion processes will likely lead to a reduction in the required length for DDT as well as removal of the form drag penalty. The use of fluidics will provide active control of the flame speed as opposed to passive control of the fixed geometry obstacles. The development of fluidic technology for PDE applications has potential to improve impulse, thrust-specific fuel consumption, and allow shorter cycle periods.
