Speed Mach facts
While investigating facts about Speed Machine and Speed Machine 2019, I found out little known, but curios details like:
An American Airforce Sergeant found a dead General while he was on his way to work at area 25, a nuclear test area in Nevada. It turns out the General had ejected while flying a captured Russian Mig at Mach 2. The force of the air at that speed instantly snapped his neck and killed him.
how to speed up time machine backup?
Lockheed Skunkworks is working on SR-72, the successor to the legendary SR-71, with a speed of Mach 6 and powered by a radical new engine which combines the features of a turbine and a scramjet.
What mach is the speed of light?
In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what spin speed to use washing machine. Here are 31 of the best facts about Speed Machine Silverstone and Speed Machine Festival 2019 I managed to collect.
what speed mach 1?
-
The SR 71 design could actually go to mach 6 speeds if it wasn't for the material melting past mach 3.3
-
Lockheed Martin is currently developing an unmanned aircraft that is capable of reaching speeds exceeding Mach 20. Able to cross the United States in under 12 minutes
-
SABRE engine technology - basically planes that go from the ground to an altitude of 25 km, reach Mach 5.5 and then become rockets, kick you back into your seat and reach a speed of Mach 25. Such planes could reach anywhere in the world in roughly 4 hours.
-
Several test pilots were once awarded astronaut wings despite not being in a space program. They managed to exceed 50 miles in altitude or more while attempting to break the world speed record in an X-15 test aircraft. They even managed to break Mach 4, 5, and 6...at up to 67 miles above earth.
-
The United States Air Force SR-71 Blackbird "is the fastest aircraft propelled by air-breathing engines. . . . It could operate safely at a maximum speed of Mach 3.3 at an altitude more than sixteen miles, or 25,908 m (85,000 ft), above the earth."
-
Once the SR71 Blackbird accelerated to mach 3, it only required about 30% throttle to maintain that speed. (ctrl F "mach")
-
The SR-71 Blackbird leaked fuel until it went fast enough that friction from the air heated the titanium body panels of the aircraft to the point that they expanded, sealing the gaps between them that enabled the aircraft to function at speeds above Mach 3.
-
The speed of sound is not a static speed, it depends on altitude AND temperature, hence the Mach scale was invented and Mach 1 being the point at which you break the sound barrier
-
The fastest speed recorded for a manned/powered aircraft was almost 50 years ago in 1967. (The X-15, Mach 6.72)
-
Mach 10 is the posted speed limit sign at the Holloman Air Force Base high speed sled test track operated by the 846th test squadron in New Mexico.
Why speed limits should be raised?
You can easily fact check why speed limits are bad by examining the linked well-known sources.
Supersonic speed is Mach 1 (around 768 miles per hour at sea level), while hypersonic speed is Mach 5. The Mach number is ratio of the aircraft speed to the speed of sound.
Years before the SR-71, and even before the AQM-60, Kelly Johnson designed a hypersonic test drone that exceeded mach 4. The X-7 prototype was made of steel and boosted to supersonic speeds, where a ramjet would take over. The first of its 131 test flights was in 1951. - source
BrahMos, jointly developed by India and Russia is the world's fastest anti-ship cruise missile in operation.The missile travels at speeds of Mach 2.8 to 3.0. A second version with speeds of upto Mach7 is planned - source
We all travel at over 87 Mach because that is the speed of Earth.
Years before the SR-71 existed, the B-58 bomber set no less than 19 world speed records. The "Hustler" was capable of mach 2.... and still holds the record for longest supersonic flight, 8024 miles. The Mig-25 Foxbat actually began development immediately after the B-58 was revealed. - source
When are school zone speed limits in effect?
MythBusters achieved a world record speed of Mach 1,5(1100 mph or 1770 kmph) with a Ping Pong ball.
How many machs is the speed of light?
NASA's hypersonic X-43A scramjet set the air speed record for an air-breathing unmanned aircraft at Mach 9.6 in 2004, nearly 7000 miles per hour.
Bill Weaver survived the breakup of a jet plane at a speed of Mach 3.18 and an altitude of 78,800 ft without being ejected from the plane.
Ernst Mach (for whom Mach numbers are named; Mach 1 = the speed of sound) was cited by Einstein as providing a partial foundation for the theory of general relativity, but Mach himself rejected both general relativity and the concept of the atom
In 1967 Maj. William "Pete" Knight flew a plane at Mach 6.7 or 4,520 mph (7,274 km/h) , a speed which remains the fastest anyone has ever flown an aircraft.
