In the context of aircraft design, the term “mass flow rate” is not typically associated with the aircraft structure itself. Mass flow rate usually relates to fluid dynamics, such as the flow of air or fuel through engines or systems in an aircraft. The mass flow rate represents the mass of fluid (air, fuel, etc.) passing through a particular area per unit of time
- 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 through which Aircraft Structure (in square meters, m²).
- V is the velocity of the Aircraft Structure (in meters per second, m/s).
