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 ...
How fast is light speed?Speed:Consider a kid running in the garden for a certain time duration and covers some distance during this time period. In this case, the speed of the kid can be given as the distance divided by the time duration and it is measured in meter per second....
Angling the glider downward, trading altitude for speed, allows the glider to fly fast enough to generate the lift needed to support its weight. The way you measure the performance of a glider is by its glide ratio. This ratio tells you how much horizontal distance a glider can travel ...
All this talk of air-tearing speed and space-brushing altitude might leave you wondering how high or how fast we've already gone. As of November 2012, the X-15 rocket plane holds the world's unofficial speed record, 4,520 mph (7,274 kph, a hypersonic Mach 6.7), and unofficial altitud...
The problem with fast flying is that disturbances can propagate only so fast through a fluid, including air. Approach or exceed that speed, and it's the difference between gliding through a pool of water and belly flopping from the high dive. Rather than fight such a brutal battle, some ...
How fast is the Parker Solar Probe traveling? The Parker Solar Probe is traveling at 430,000 mph, making it the "fastest human-made object in history," Rayl said. MORE: Binary star system found near the Milky Way's black hole: An 'amazing' discovery, astrophysicists say ...
How fast does air come out of a jet engine?Commercial Jet SpeedsCommercial jets typically fly at a speed that ranges from 400 mph to almost 600 mph. Even though they travel fast, the air that comes from their engines travels even faster....
This is how the world's fastest, most technologically advanced set of wheels is made: the wheels for Bloodhound, Richard Noble's land-speed-record car that, all being well, should do 1,000mph in the hands of Wing Commander Andy Green on South Africa's Hakskeen Pan; wheels that must wi...
Japan’s high-speed rail revolution The next generation of bullet trains, known as ALFA-X, is currently being tested at speeds of almost 250 mph (400 kph), although the service maximum will be “only” 225 mph. The defining features of these and other recent Shinkansen trains are their ex...
