Recent interest in pulse detonation engines (PDEs) has resulted in several experimental andtheoretical studies related to realizing multi-cycle detonations in tubes that simulate engineoperating conditions. These studies make a clear case that pulse detonation engines provide thepotential for higher specific impulse, reduced complexity and lower operational costs ascompared to current gas turbine technology. For air breathing applications, hydrocarbon-airpropellant combinations are being considered, which are particularly difficult to detonate withina practical length. In addition, a key barrier to the realization of an operational PDE is achievingreliable and repeatable detonations in the shortest distance possible to minimize system weight.Dr. Lee has focused on several areas of fundamental research related to the pulse detonationengine and pulse detonation engine driven ejector. This talk will briefly discuss the fundamentalunderstanding of detonation combustion and its applications including the deflagration-todetonation transition (DDT) process, detonation transition to a bigger thrust chamber, the PDEdriven thrust augmentation, and the plasma-assisted PDE.
