Can commercial planes fly at the speed of sound?
Among the several reasons commercial civilian aircraft don’t fly faster than the speed of sound is the objectionable sonic boom that going supersonic results in. Now, Nasa is working on developing an experimental plane that can fly at roughly double the speed of a commercial jet while keeping the aircraft quiet.
What is the speed of sound in airplane?
As the local temperature decreases, the sound speed also decreases, so for a plane flying at 35,000 feetwhere the ambient temperature is 54 Cthe local speed of sound is 295 meters per second (660 miles per hour).
How fast is supersonic in FPS?
1,100 feet per second
Generally speaking, the speed of sound is 1,100 feet per second, so anything at that speed or above is considered to be supersonic.
Can a 747 fly faster than the speed of sound?
Question: What is the fastest airliner and how fast does it fly? — submitted by reader James Kriplean, Knoxville, Tenn. Answer: The Boeing 747 can cruise at 92% of the speed of sound, Mach .
How fast do commercial planes fly mph?
around 460-575 mph
Most commercial aircraft typically fly at around 460-575 mph, or 740-930 km/h, according to Flight Deck Friend. But private jet speed can vary depending on a variety of factors, such as the weight onboard and the weather conditions.
Why can’t commercial airplanes fly faster?
Airplanes don’t fly faster because they burn more fuel at higher speeds, meaning that it isn’t economical. In addition, operating at higher speeds puts more stress on the engines as well as the airplane fuselage, which causes them to wear down faster.
What is the speed of sound in FPS?
At 20 °C (68 °F), the speed of sound in air is about 343 metres per second (1,235 km/h; 1,125 ft/s; 767 mph; 667 kn), or a kilometre in 2.9 s or a mile in 4.7 s.
What is the sound barrier in FPS?
The sound barrier is usually broken anywhere between 1,060 to 1,200 feet per second, depending on the conditions. The speed of sound is influenced by outside factors such as elevation, air pressure, and air temperature.
What is subsonic speed FPS?
Quite simply, subsonic ammunition is any cartridge that propels its projectile at a velocity that is below the speed of sound—approximately 1100 fps depending on atmospheric conditions and elevation.
Are private jets faster than commercial jets?
Private jets often fly at the same speed as commercial jets, which on average, fly 547–575 mph when they reach cruising altitude. Smaller private jets and private aircraft, on the other hand, often have the capability of flying faster than commercial airplanes.
How fast does a 747 fly in mph?
The top speed of the Boeing 747 itself is about 570 mph, and this flight maxed out at 825 mph. The difference between “ground speed” (zero bonus) and “air speed” (200+ mph bonus) is also why this speed, while technically faster than the speed of sound, didn’t ever go supersonic.
What Is the Speed of Sound in What Is the Speed of Sound in Fps? The speed of sound, known as Mach 1, varies depending on the medium through which a sound wave propagates. In dry, sea level air that is around 25 degrees Celsius, Mach 1 is equal to 340.29 meters per second, or 1,122.96 feet per second.
What is the speed of sound in sea level air?
In dry, sea level air that is around 25 degrees Celsius, Mach 1 is equal to 340.29 meters per second, or 1,122.96 feet per second.
What’s the average speed of a commercial jet?
How fast do commercial passenger jets fly? A typical commercial passenger jet flies at a speed of about 400 – 500 knots which is around 460 – 575 mph when cruising at about 36,000ft. This is about Mach 0.75 – 0.85 or in other words, about 75-85% of the speed of sound.
Are there any airlines that fly at supersonic speeds?
There hasn’t been a supersonic passenger airliner since the days of the Concorde. Now a test aircraft is ready to try again. Another plans to hit four times the speed of sound and enter the hypersonic age. It’s a fairly small aircraft, with a length of just 21 meters (68.8 feet).
