We humans have a wonderful ability to keep developing, innovating, and engineering bigger, better, and faster contraptions. Close to Earth, we’ve been soaring through the skies in airplanes since 1903 thanks to the Wright brothers, and we’ve been launching spacecraft into space since 1957 when the Soviet Union rocketed the Sputnik satellite above our heads.
So why not try even further, and even faster using less energy and fuel? How does a flight from New York to Los Angeles in a mere 30 minutes instead of six hours spent sitting next to a stranger in cramped conditions sound? This may soon be possible thanks to a team of engineers from the University of Central Florida.
The team discovered a way of stabilizing detonation for hypersonic propulsion by creating a hypersonic reaction chamber for jet propulsions.
This breakthrough allows for a potential way to develop, and integrate ultra-high-speed detonation technology that allows for hypersonic propulsion, and advanced power systems, as the team explained in its study published in the journal Proceedings of the National Academy of Sciences.
They’re not the only ones working on such technology. For example, in late 2020 China was testing a hypersonic jet engine that’s able to go 16 times the speed of sound in a one-of-a-kind wind tunnel in Beijing. If this jet engine, called sodramjet, was used, you’d be able to travel anywhere on Earth in just two hours.
Other agencies, companies, and governments are focusing their energy on the future of hypersonic flight, not only for fast commercial travel across the world but to also improve how spacecraft engines launch up into space.
