New and improved air and space travel may be here.

00:00The key to hypersonic air and space travel could lie in generating a never-ending detonation
00:10that propels vehicles seamlessly into and out of the atmosphere, and scientists may
00:16have just figured out a way to make this possible.
00:19Detonations are powerful explosions that blast outwards faster than the speed of sound.
00:25That's why scientists for so long have wanted to build aircrafts that can harness these
00:29great amounts of energy.
00:31They could enable us to fly from New York to London in under an hour.
00:35However, the problem up until now has been controlling detonations and making them last
00:41more than a few microseconds.
00:43Recently, a team from the University of Central Florida set out to tackle these challenges.
00:49What we're trying to do here is control that detonation.
00:53We want to freeze it in space and harness that energy, said team researcher Kareem Ahmed.
00:59Theoretically, such an explosion could propel aircrafts up to speeds 17 times the speed
01:05of sound, which would get rid of the need to use rockets to carry aircrafts up and out
01:10of the atmosphere.
01:11To do so, the team funneled a mixture of air and hydrogen gas towards a ramp at extremely
01:17fast speeds and used a propulsion system to generate a shock wave that rapidly caused
01:23the mixture to detonate and blast exhaust gas.
01:26Ahmed and his team successfully created a detonation that lasted for three seconds in
01:32a fixed position, confirming that they were able to stabilize the explosion.
01:37Now, the challenge lies in figuring out how to change the air speed, fuel mix, ramp angle
01:43while maintaining explosion stability.
