The lift per unit span at any specific station, often denoted as L′(yn), represents the distribution of lift along the span of an aircraft wing. It is a measure of the lift force generated by the wing at a particular location or spanwise station. This concept is essential for understanding the aerodynamic characteristics of an aircraft and how lift is distributed across its wingspan.
- L′(yn) is the lift per unit span at the spanwise station “yn.”
- 𝜌∞ is the air density of the free stream airflow.
- V∞ is the true airspeed of the aircraft.
- Γ(yn) represents the circulation around the wing section at the station “yn.”
