New propulsion system could allow jets to reach speeds of up to Mach 17 without releasing powerful shock waves that would damage the environment

  • The new propulsion system contains a chamber to stabilize the detonation
  • Instead of the detonation going up or down, it is captured on a ramp
  • This allows it to be used as a power source and not to be released around the craft
  • Experts conducted an experiment that stabilized him for three seconds
  • This is the first time that a detonation has been stabilized experimentally
  • Scientists say this method will provide speeds from Mach 6 to Mach 17










New technology could make hypersonic flight a reality by allowing jets to reach up to Mach 17 without triggering an uncontrollable detonation.

Scientists at the University of Central Florida have developed a new propulsion system to stabilize detonation, which is a type of explosion that sends out waves faster than the speed of sound.

The facility contains a chamber with a 30 degree angle ramp near the thruster mixing chamber which stabilized the oblique detonation wave for three seconds in a controlled experiment – previous work only captured it for milliseconds.

This controlled method uses the toothing as a power source that could allow a jet to travel at speeds of Mach 6 to 17, or over 4,600 to 13,000 miles per hour, while stopping the powerful shock that could damage the environment of the machine.

“There is an intensifying international effort to develop robust propulsion systems for hypersonic and supersonic flight that would allow passage through our atmosphere at very high speeds and also allow efficient entry and exit of planetary atmospheres,” said said study co-author Kareem Ahmed, associate professor in the Department of Mechanical and Aerospace Engineering at UCF.

“The discovery of the stabilization of a detonation – the most powerful form of intense reaction and release of energy – has the potential to revolutionize hypersonic propulsion and energy systems.”

The technology improves the efficiency of jet propulsion engines so that more power is generated while using less fuel than traditional propulsion engines, thus lightening the fuel load and reducing costs and emissions.

In addition to faster air travel, the system could also be used in rockets for space missions to make them lighter by requiring less fuel, traveling farther and burning cleaner.

Scientists designed a small series of 2.5-foot-long chambers to mimic those that would fire a jet at Mach speeds, Live Science reports.

The chambers mix air and fuel together to produce a powerful combustion, which was released into the new chamber as a detonation.

And the small bang remained in a stabilized position for three seconds.

Ahmed told Live Science that although short, the timing was enough to prove that the innovation is capable of controlling a bang on its way up or down.

“This is the first time that a detonation has been stabilized experimentally,” Ahmed said.

“We are finally able to maintain the detonation in space as an oblique detonation. It’s almost like freezing an intense explosion in physical space.

This controlled method uses the toothing for a power source that could allow a jet to travel at speeds of Mach 6 to 17, or over 4,600 to 13,000 miles per hour, while stopping the powerful shock. which could damage the environment of the machine.

Gabriel Goodwin, an aerospace engineer at the Naval Research Laboratory at the Naval Center for Space Technology and co-author of the study, says their research helps answer many fundamental questions surrounding oblique detonation wave engines.

Goodwin’s role in the study was to use computational fluid dynamics codes from the Naval Research Laboratory to simulate experiments performed by Ahmed’s group.

“Studies like this are crucial in advancing our understanding of these complex phenomena and bringing us closer to the development of systems at the engineering scale,” says Goodwin.

“This work is exciting and pushes the boundaries of simulation and experimentation,” says Goodwin. “I am honored to be a part of it. “
