In aircraft design, the term “velocity” of an airframe typically refers to the speed at which the aircraft is traveling through the air, which is commonly measured in units like meters per second (m/s) or knots (nautical miles per hour).
- ṁ is the mass flow rate in kilograms per second (kg/s).
- ρ is the air density in kilograms per cubic meter (kg/m³).
- A is the cross-sectional area of Airframe (in square meters, m²).
- V is the velocity of the Airframe (in meters per second, m/s).
