Flying at Speeds up to Mach 16 Could Become Reality In their latest research published Monday in the journal Proceedings of the National Academy of Sciences, the researchers discovered a way to stabilize the detonation needed for hypersonic propulsion by creating a special hypersonic reaction chamber for jet engines. “There is an intensifying international effort to develop robust propulsion systems for hypersonic and supersonic flight that would allow flight through our atmosphere at very high speeds and also allow efficient entry and exit from planetary atmospheres,” says study co-author Kareem Ahmed, an associate professor in UCF’s Department of Mechanical and Aerospace Engineering. “The discovery of stabilizing a detonation — the most powerful form of intense reaction and energy release — has the potential to revolutionize hypersonic propulsion and energy systems.”
