Coefficient of Lift Design (Cldesign) typically refers to the maximum coefficient of lift that an aircraft can achieve at a specific configuration. The maximum coefficient of lift (CLmax) is a crucial parameter as it determines the maximum lift an aircraft can generate before it reaches a stall condition.
Formula: The maximum coefficient of lift (CLmax) is not expressed through a single formula; instead, it is determined through extensive aerodynamic testing and analysis. Engineers use wind tunnel testing, computational fluid dynamics (CFD) simulations, and flight testing to establish the CLmax for a particular aircraft design.
- CLmax is the maximum coefficient of lift (dimensionless).
- Lift is the actual lift force produced by the aircraft’s wing (in newtons, N).
- ρ (rho) is the air density (in kilograms per cubic meter, kg/m³).
- V is the velocity of the aircraft relative to the air (in meters per second, m/s).
- S is the reference wing area (in square meters, m²).
