6 lis 2013 · By 2030, an uncrewed spyplane will be able to fly at Mach 6 – six times the speed of sound. Engineers at Lockheed Martin’s Skunk Works lab in Palmdale, California, claim to have solved a...
2 dni temu · The Texan aerospace company is currently working on the Stargazer, a high-speed aircraft that moves three times faster than the Concorde at about six times the speed of sound and in much higher altitudes (likely over 110,000 feet).
9 paź 2020 · Above about 6 million times Earth’s atmospheric pressure, the sound speed limit would be broken, the calculations suggest.
13 maj 2021 · For speeds greater than five times the speed of sound, M > 5, the flow is said to be hypersonic. At these speeds, some of the energy of the object now goes into exciting the chemical bonds which hold together the nitrogen and oxygen molecules of the air.
Felix Baumgartner broke the speed of sound reaching an estimated speed of 1,357.6 kmh / 843.6 mph / Mach 1.25 jumping from the stratosphere, which when certified will make him the first man to break the speed of sound in freefall while delivering valuable data for future space exploration.
24 paź 2012 · Wolfram|Alpha tells us the jump was equivalent to a fall from 4.4 Mount Everests stacked on top of each other, or falling 93% of the length of a marathon. At 24.26 miles above the Earth, the atmosphere is very thin and cold, only about -14 degrees Fahrenheit on average.
In Earth's atmosphere, the speed of sound varies greatly from about 295 m/s (1,060 km/h; 660 mph) at high altitudes to about 355 m/s (1,280 km/h; 790 mph) at high temperatures.
