The average Mach number in flight mechanics represents the ratio of an aircraft’s average true airspeed to the speed of sound in the surrounding air. It is a dimensionless parameter crucial for characterizing an aircraft’s speed, particularly in high-speed and supersonic flight regimes. The formula to calculate average Mach Number as follows:
Where:
- Vavg is the average velocity in m/s
- aSL is the sound of speed at sea level in m/s.
- Mavg is the Average Mach number.
