C’est quoi Mac 20 ?
Des vitesses de l’ordre de Mach 20 imposent des matériaux conçus pour supporter des températures de quelque 2.000 °C mais aussi des commandes de vol particulières. E. B.
Quelle vitesse représente Mac 2 ?
L’avion supersonique Boom, le nouveau Concorde ? L’avion (qui n’a pas encore de vrai nom officiel) pourra atteindre sur le papier la vitesse Mach 2,2 (soit 2,2 fois la vitesse du son, environ 2 300 km/h). E. B.

What does Mach 23 mean?
- Mach 23 to mph conversion. Mach is the ratio of an object’s speed to the speed of sound. For example, something traveling at Mach 5 is traveling at 5 times the speed of sound. The speed of sound varies depending on many factors. In dry air, at 0 degrees Celsius, the speed of sound is about 331.3 meters per second.
How fast is the speed of sound Mach 23?
- At sea level in clear and calm conditions the speed of sound is approximately 760mph. How fast Mach 23 is depends upon where you are and what the temperature and local pressure are. At sea level on Earth the speed of sound is around 660 mph on an average day, so Mach 23 is 15,410 mph.
What is the relationship between Mach number and altitude?
- Technical answer: Mach number is the ratio of velocity to speed of sound. Speed of sound is a function of temperature, which is a function of altitude (though at Mach 23, you’d better be above the thermopause), so it really depends.
