Hypersonic is, obviously, supersonic on steroids. But while "supersonic" has the clear cut definition of being faster than the speed of sound (Mach 1), hypersonic is a little fuzzier. Generally, hypersonic speeds are the point at which the molecules of air that surround the aircraft start ...
What Is Hypersonic Speed? Hypersonic speed is five times the speed of sound. Scientists measure speeds this fast with a Mach number, named for Austrian physicist Ernst Mach. Sound has a speed of Mach 1 and anything Mach 5 or above is considered hypersonic. While the speed of sound changes ...
Speeds swifter than Mach 10 are considered high hypersonic. If you've ever heard a supersonic aircraft fly overhead, then you've probably heard a sonic boom. Once an airplane attains Mach 1, the sound waves emitted by the plane can't speed ahead of it. Instead, these waves accumulate ...

Simulating flow conditions with computational flow diagnostics (CFD) is computationally expensive (if not impossible), and so to replicate the flow conditions, researchers at Purdue fabricated a giant burner to recreate the hot, fast, high pressure experienced in hypersonic flight. In short, they ...
The result is an immense explosion with a 10,000-kiloton yield — 700 times more powerful than the Little Boy explosion. Nuclear Bomb Delivery This graphic shows a comparison of ballistic and hypersonic flight trajectories. Many countries are now capable of delivering nuclear bombs via ballistic...
It ascended upwards at hypersonic speeds through a field of lightning bolts. While riding on these lightning bolts, the Skrill is capable of travelling a couple of kilometers in a tenth of a second, which would mean that it can travel at several times the speed of sound. This maneuver can...
Engines that work this way are called ramjets, and since they need the air to be traveling fast, are really suitable only for supersonic and hypersonic (faster-than-sound) planes. Air moving faster than sound as it enters the engine is compressed and slowed down dramatically, to subsonic ...
A rocket engine is generally throwing mass in the form of a high-pressure gas. The engine throws the mass of gas out in one direction in order to get a reaction in the opposite direction. The mass comes from the weight of the fuel that the rocket engine burns. The burning process accel...
