Mach cones are shock waves that form in supersonic flow when an object moves faster than the speed of sound. They are cone-shaped regions of compressed air that extend outward from the object in the direction of its motion. These shock waves are created when the object pushes air molecules aside faster than they can move out of the way, causing a sudden increase in pressure and temperature.
The mach cone angle is important in supersonic flow dynamics because it represents the angle at which shock waves propagate from an object moving faster than the speed of sound. Understanding this angle helps researchers analyze and predict the behavior of supersonic flow around objects, such as aircraft or projectiles, which is crucial for designing efficient and safe aerodynamic systems.
Supersonic speed is defined as speeds greater than the speed of sound, which is approximately 343 meters per second (767 mph) at sea level. Aircraft flying at supersonic speeds typically travel at speeds ranging from Mach 1 to Mach 5, or roughly 343 meters per second to 1716 meters per second.
At Mach number 1 at the throat section of a converging-diverging nozzle, the flow is said to be choked. This occurs when the flow velocity reaches the local speed of sound, leading to a critical point where the mass flow rate cannot increase any further. The design of the nozzle is crucial to achieving this critical condition for optimal performance in applications such as rocket engines and supersonic aircraft.
They are called Supersonic aircraft. Some aircraft can only do that. Some planes have reached even Hypersonic speeds.
The Mach number at the throat section of a converging-diverging nozzle is 1. This is where the flow reaches its sonic condition, known as choked flow.

A supersonic plane is one that is flying faster than the speed of sound, or Mach 1. A hypersonic plane flies at a speed of Mach 5, so is much faster than a supersonic plane. Mach numbers are used for speeds greater than the speed of sound.
Critical Mach Number, or Mcr, refers to the lowest Mach number that air going over and around an aircraft can reach the speed of sound. If an airplane goes over its Mcr, handling might be greatly affected.
The threshold for supersonic speed is 761 mph in a temperature like 70 degrees. Supersonic speed is any speed greater than the speed of sound (mach 1) and a speed five times the speed of sound (mach 5?) is referred to as hypersonic speed.
Close! Actually, Mach-1 is the speed of sound. anything above Mach-1 (Mach-(1-5)) is supersonic, all the way up to Mach-5, at which point an object is called "Hypersonic". Sometimes speeds above Mach-10 are referred to as "High-Hypersonic". So, a jet moving at Mach-1 wouldn't actually be traveling FASTER than sound, it would be traveling AS FAST as sound.
Go over MACH 1. Preferably in a military jet.
One half the speed of sound. This is subsonic.
Answer Mach 12 Supersonic Speed usually refers to speed just above Mach 1, or as high as Mach 3. Hyper-speed is a higher range but there is no set definition.

The speed of sound is proportionally less and vary s according to altitude. when ever air craft exceeds the speed of sound it is defined as i mach. those air crafts capable of crossing sound speed is called supersonic.
One supersonic aircraft is the F-15 Eagle. -Supersonic means it can fly faster than Mach 1, the speed of sound. Most fighter jets today are supersonic, in fact many fly more than twice the speed of sound.
