What happens when the speed of an airplane is exactly equal to the speed of sound?

When the aircraft is just the same as the speed of sound, it belongs to the transonic stage, and the shock wave will be generated on the aircraft, which will form a very large drag, and the flight at this stage is unstable and very uneconomical. The speed of each point on the plane is not the same, in order to prevent the creation of shock wave drag. There will be a Mach meter on the plane, which will show the maximum number of Mach that can be flown at any point on the plane below the speed of sound.

The phenomenon you said will not happen, the so-called sound is the fluctuation of the air, when the plane flies at high speed, the air will be highly compressed, and the station, that is, the place where the speed is zero, will produce high temperature, high pressure, and high resistance.

The aircraft flies at supersonic speeds, which requires a high level of strength for the airframe. Because, the flight speed of the aircraft exceeds the speed of sound, the aircraft will catch up with the noise generated by the flight of the aircraft, which will produce a large squeezing force on the air and produce a sonic boom, which is enough to shatter the glass when the aircraft flies at low altitude and supersonic speed. But this energy doesn't accumulate forever, the sonic boom is the release of energy.

No, when you exceed the speed of sound, you will break the sound barrier and produce a sonic boom, you can search for "beyond the speed and reality of sound". Hehe, the answer is not exact, sorry

To put it simply, supersonic aircraft must accelerate from subsonic speed to supersonic speed before supersonic flight, and the transonic stage has to go through a time when the speed and speed of sound are equal, and if the plane is broken, there will be no supersonic flight.

will cause resonance (physics) The ending you know how serious it is!

What happens when an airplane is faster than the speed of sound? The camera records the whole process!

Problem description: The speed of the aircraft is either supersonic or subsonic, why can't it happen to be the speed of sound?

Analysis: When the speed of the aircraft reaches the speed of sound, the pilot will hear a loud "boom" sound from the surroundings, and gradually increase, this noise can sometimes deaf the pilot's ears, and even detonate the aircraft, which is the "sonic boom".

Because when the speed of the aircraft reaches the speed of sound, the aircraft "catches" the sound when it "races" against the sound, and the sound waves cannot be far away and rough; The noise emitted by the engine is continuous, so if the aircraft keeps flying at the speed of sound, the volume will continue to superimpose, and it can even reach the disintegration of the aircraft.

To avoid tragedy, aircraft (especially civil aviation) should try to avoid flying for long periods of time.

I guess you're probably talking about a supersonic aircraft. We have all seen one of them, which is the Concord style. (now retired).

Concorde; Also known as the Harmony airliner, the Taiwanese Concorde airliner) is a supersonic airliner jointly developed by the United Kingdom and France, and the design leader is MrLucien Servanty, a total of only 20 such aircraft were built. It has a maximum flight speed of up to Mach and a cruising altitude of 18,000 meters.

The Concorde was developed in 1969 and commenced commercial flight on 21 January 1976. British Airways and Air France use Concorde aircraft to operate transatlantic flights.

The Concorde had a total of four turbojet engines. The engine was developed by Rolls-Royce in the UK and R0LLS-Royce Snecma. The engine type is "Olympus" 593MK610 turbojet (Olympus 593).

Single thrust kiloN (38,000 lbs). The engine is equipped with an afterburner (afterburner) that is normally used only in supersonic fighters. The Concorde can fly faster than twice the speed of sound, with a maximum speed of Mach and a cruising altitude of 18,000 meters and a cruising speed of 2,150 kilometers per hour.

Ordinary planes, are we good with Boeing airliners? Take the example of the 747, which is the most common for transoceanic flights:

The Boeing 747, also known as the Jumbo Jet, is a double-deck four-engine aircraft, one of the most recognizable passenger aircraft in the world, and the world's first wide-body civil airliner, manufactured by the Boeing Civil Aircraft Group of the United States. The Boeing 747 prototype is twice the size of the Boeing 707, which was widely used in the 1960s. The Boeing 747 held the record for the world's largest aircraft by passenger capacity for 37 years from its inception in 1970 until the A380 entered service.

Its cruising speed is Mach; Approx. 860 km/h.

The absolute take-off speed and minimum flight speed are meaningless, and scientific analysis results can only be obtained in combination with the actual situation. That is, it is still slower than the speed of sound, but it is already very close to the speed of sound. In fact, it is still subsonic, but it is faster than the usual subsonic, so the word "high" is added to distinguish it.

How fast is it flying at about the speed of solsonic speed? Slightly less than 1000 km/h.

To put it simply:

1. The take-off speed of different aircraft is different, so it should be analyzed differently according to different situations. The take-off speed of a modern fighter jet from an airfield is generally 350 kilometers per hour.

2. The speed of sound is when the relative velocity of the aircraft in the atmosphere and the air reaches the speed of sound, and subsonic speed is lower than this speed.

3. The fastest known aircraft is the American SR-71 Blackbird reconnaissance plane, which can reach a maximum speed of 3,529 kilometers per hour. Faster than the bullets of the rifle.

1。The take-off speed of the plane depends on what type of aircraft, if it is a Cessna 172, it can take off at 65 knots.

If it's a 737-700, it will take off at about 125 knots!!

1 knot = 1 nautical mile hour.

2。The speed of sound is equal to the speed at which sound travels!

Subsonic speed is less than the speed of sound, less than the speed of sound.

Mach 1 = 1 speed of sound.

The Mach number is subsonic.

3。The fastest civil aircraft is the Concorde, which can fly at 2 times the speed of sound! But there was an accident before, and it was not economical, so I retired!

Military ones can be faster There is no fastest, only faster

Hello dear, according to the situation you described, in fact, the speed of the plane is usually much faster than the speed at which we can walk on the ground. But when you're on an airplane, you may not feel the speed of the airplane because you're sitting in a relatively stationary object, and the plane usually flies in a relatively smooth manner. Additionally, flights are usually flying at high altitudes, so the ground and other sights you see move slowly, which may also make you feel less like the speed of the plane.

Of course, during takeoff and bridge landing, you may feel the acceleration and deceleration of the aircraft, and that's when you can really feel the speed of the aircraft.

The flight speed of the aircraft is about 200 4000 kilometers per hour. It should be noted that there are many types of aircraft nowadays, and the flight speed will vary greatly. For example, civil aircraft generally fly at a speed of 800 to 1000 kilometers per hour.

In the case of fighter jets, the flight speed tends to be 200 400 kilometers per hour, while supersonic aircraft will fly even faster, generally reaching 1200 kilometers per hour by 4000 kilometers.

For example, the common Boeing 737 can reach a cruising speed of 900 kilometers per hour, while the Boeing 747 is faster than the Boeing 737, and the fastest cruise speed can be close to 1120 kilometers per small fluid trap. The flight speed and take-off speed of an airplane are different. Take-off speeds are generally slow, with most aircraft not exceeding 400 kilometers per hour.

In our country, the fastest flight speed of civil aircraft can reach 2600 kilometers per hour, but this speed is too fast, and the country does not allow civil aircraft to fly so fast. Because the plane flying too fast will bring more potential safety hazards, which may affect the personal safety of the aircraft and passengers, so the speed limit of civil aircraft is basically changed.

Airplanes are a mode of transportation that many passengers choose when traveling. The speed of the plane is relatively fast, which can greatly save time on the road. There are two types of aircraft, one is military aircraft and the other is civilian aircraft.

Military aircraft are mainly used in the military sector, while civil aircraft are non-military aircraft such as passenger planes or cargo planes.
