By library research and an interview with Dr. Roger Reed of the Metals and Materials Engineering Department of the University of British Columbia, it is shown that Pulse Detonation Engine (PDE) technology is more efficient than current engine types by virtue of its mechanical simplicity and thermodynamic efficiency. As the PDE produces a higher specific thrust than comparable ramjet engines at speeds of up to approximately Mach 2.3, it is suitable for use as part of a multi-stage propulsion system. The PDE can provide static thrust for a ramjet or scramjet engine, or operate in combination with turbofan systems. As such, it sees potential applications in many sectors of the aerospace, aeronautic, and military industries. However, there remain engineering challenges that must be overcome before the PDE can see practical use. Current methods for initiating the detonation process need refinement. To this end, both Pratt & Whitney and General Electric have developed different processes to accomplish this. Also, current materials used in jet engines, such as Nickel-based super-alloys, are inadequate to withstand the extreme heat and pressure generated by the detonation cycle. Therefore, new materials must be developed for this purpose.
