The drag component that results from the generation of lift by an aircraft’s wings. It is a critical parameter used to assess the efficiency of an aircraft’s lift production and its impact on overall aerodynamic performance.
- lv: This likely represents the lift-induced drag coefficient for an aircraft.
- L’v: This may be the change in lift with respect to a change in the vertical velocity (sometimes represented as dL/dv), which can be influenced by changes in the angle of attack or other factors.
- ρ: This represents the air density.
- u0: This is probably the airspeed or the flight velocity.
- S: This typically stands for the reference wing area.
- b: This is likely the wingspan of the aircraft.
