13 maj 2021 · Here's another JavaScript program to calculate speed of sound and Mach number for different planets, altitudes, and speed. You can use this calculator to determine the Mach number of a aircraft at a given speed and altitude on Earth or Mars.
26 kwi 2024 · The Mach number is the ratio of the speed of the aircraft, or the speed of the gas, to the speed of sound in the gas. The speed of sound is equal to the speed of transmission of small, isentropic disturbances in the flow.
Mach number is a function of temperature and true airspeed. Aircraft flight instruments, however, operate using pressure differential to compute Mach number, not temperature. Assuming air to be an ideal gas, the formula to compute Mach number in a subsonic compressible flow is found from Bernoulli's equation for M < 1 (above): [9]
Mach number is the ratio of the speed of an object to the speed of sound in the surrounding medium. It plays a critical role in understanding various flight regimes, as it helps categorize the behavior of aircraft in different atmospheric conditions and speeds, influencing aspects like drag, engine performance, and compressibility effects.
19 maj 2009 · The Mach number is the ratio of the speed of the aircraft to the speed of sound. Flight that is faster than Mach 1 is supersonic. Supersonic includes speeds up to five times faster than the speed of sound, or Mach 5.
9 mar 2023 · Mach is the ratio of the velocity of an object relative to the speed of sound. Regarding aircraft, Mach measures how fast the plane moves through the air mass at its current altitude relative to the speed of sound, which is 761 miles per hour at sea level on a standard day.
