nv (n or n_z): The normal load factor (n) represents the ratio of the vertical aerodynamic force (lift) to the weight of the aircraft. It is a measure of the G-forces experienced by the aircraft in the vertical direction during flight. Positive values of n indicate an upward force exceeding the weight of the aircraft, while negative values indicate a downward force.
- nv: This likely represents the normal load factor in flight (sometimes denoted as “n” or “n_z”), which is the ratio of the vertical aerodynamic force (lift) to the weight of the aircraft.
- Nv: This may be the change in the normal load factor with respect to a change in velocity (sometimes represented as dn/dv), indicating how the load factor changes as the aircraft’s speed changes.
- 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
