How Fast to Break the Sound Barrier?
The speed of sound is about 1,225 kilometers per hour (km/h) in standard conditions. This means that it would take about 12 minutes for the average person to walk one kilometer, and just over 9 hours to walk 1,000 kilometers. To break the sound barrier, you would need to travel at a speed greater than 1,225 km/h.
How fast does it take to break the sound barrier? It turns out that there is no definitive answer to this question. The speed of sound is affected by a number of factors, including temperature, humidity, and altitude.
As a result, the speed at which you need to travel to break the sound barrier can vary depending on these conditions. In general, though, it is thought that you need to be travelling at around 761 mph (1,225 km/h) to break the sound barrier. This is just over Mach 1, which is the measure used to describe the speed of sound.
Mach 1 is equal to the speed of sound in dry air at sea level and standard temperature (15 degrees Celsius). So how fast have people actually gone in order to break the sound barrier? In 1947, Chuck Yeager became the first person confirmed to have broken the sound barrier when he reached a speed of 700 mph (1,126 km/h) in his experimental aircraft called the Bell X-1.
However, there are reports that other pilots were able to reach supersonic speeds before Yeager. More recently, in 2004, NASA’s Helios solar-powered unmanned aerial vehicle reached a top speed of 96 knots (111 mph or 179 km/h). While this may not seem like much compared to Yeager’s record-breaking flight all those years ago, it’s important to remember that Helios was powered by nothing but sunlight!
How Fast Do You Have to Go to Break the Sound Barrier in Km H
To break the sound barrier, you need to be travelling at approximately 1,225 km/h. This is the speed of sound in dry air at sea level. In order to reach this speed, you would need a very powerful engine, and your vehicle would need to be extremely aerodynamic.
Even then, it’s not possible for a human-made object to travel faster than the speed of sound – so breaking the sound barrier is impossible!
How Fast Can You Go to Break the Sound Barrier?
Assuming you are referring to an aircraft, the speed of sound is about 767 miles per hour (mph) or 1,235 kilometers per hour (km/h). To break the sound barrier, an aircraft must be capable of flying at least that fast. The actual speed required depends on a number of factors, including the altitude of the flight and the temperature of the air.
The first manned aircraft to fly faster than the speed of sound was the Bell X-1, which was piloted by Chuck Yeager in 1947. The X-1 was a rocket-powered plane that was dropped from a bomber before igniting its engines. It reached a top speed of 700 mph (1,127 km/h).
Other notable supersonic aircraft include the North American X-15 (which set numerous altitude and speed records in the 1960s), NASA’s Space Shuttle orbiters (all of which were capable of reaching Mach 25 during reentry), and various fighter jets such as the MiG-21 and F-22 Raptor. The current land vehicle speed record is held by Bloodhound SSC, a British car that is designed to reach 1,000 mph (1,609 km/h). Bloodhound SSC is powered by both a jet engine and a rocket; it has yet to attempt its record run.
Is It Legal to Break the Sound Barrier?
Yes, it is legal to break the sound barrier. There are no laws against it. In fact, there are many people who have broken the sound barrier, both in aircraft and on land.
The world record for the fastest land speed is held by British driver Andy Green, who reached a speed of 763 miles per hour (1,228 kilometers per hour) in a car called Bloodhound SSC in October 1997. On October 15, 1947, American test pilot Chuck Yeager became the first person to fly an airplane faster than the speed of sound. He did it in an experimental rocket-powered plane called the Bell X-1.
Has a 747 Ever Broken the Sound Barrier?
Yes, a 747 has broken the sound barrier. On January 10th, 1973, in an attempt to test the newly designed Boeing 747-100’s capabilities, Captain William “Bill” Powell took off from Edwards Air Force Base in California. After reaching an altitude of 45,000 feet, he pushed the nose over and accelerated toward the ground.
At just under 662 miles per hour, he became the first person to fly a jumbo jet faster than the speed of sound. Though it was not an intentional flight into supersonic territory, it did prove that the new 747 could indeed reach high speeds.
How Fast Do Jets Go to Break the Sound Barrier?
The Lockheed SR-71 “Blackbird” is a long-range, Mach 3+ strategic reconnaissance aircraft that was operated by the United States Air Force. It was developed as a black project from the Lockheed A-12 reconnaissance aircraft in the 1960s by Lockheed and its Skunk Works division. American aerospace engineer Clarence “Kelly” Johnson was responsible for many of the airplane’s innovative designs.[2]
During aerial reconnaissance missions, the SR-71 operated at high speeds and altitudes to allow it to outrace threats. If a surface-to-air missile launch were detected, the standard evasive action was simply to accelerate and outfly the missile.[3] The SR-71 had no defensive armament.
While flying at Mach 3.2, typical flight duration was 1 hour and 42 minutes; thiswas due to fuel consumption rates of approximately one gallon per second (4 liters per second).[4][5] The ground crew required an average of 12 man hours of maintenance time per flight hour,[6] including refueling and rearming[7] while on alert status 15 minutes before take off in case of recall during takeoff roll.[8][9][10] Due to friction heating, airframe skin temperature increased during Mach 3 flights; temperatures reached as high as 470 °F (243 °C) near engine exhaust vents.
All exterior paint burned off on flights; pieces of metal expanded at different rates causing minor structural damage that could easily be repaired upon landing.[11][12][13], Jets typically fly anywhere between 500 mph and 600 mph, but can reach speeds upwards of 700 mph in some cases.
To break the sound barrier, a jet must be travelling at around 767 mph – which is about Mach 1. However, most commercial jets are not designed to travel this fast as it would cause too much wear and tear on the plane itself. There are only a handful of planes that have been designed to travel fast enough to break the sound barrier, with one of them being the Concorde – which could reach speeds of up to 1350 mph!
What Happens When You Break the Sound Barrier
Conclusion
The blog post discusses how fast an object needs to travel in order to break the sound barrier. The author explains that the speed of sound is about 343 meters per second, and that an object needs to be moving at least this fast in order to break the sound barrier. The author goes on to discuss how supersonic aircraft are able to fly faster than the speed of sound, and how this is done by using special engines called afterburners.
