The normal force coefficient (CZ) is a dimensionless parameter in aerodynamics that characterizes the lift generated by an airfoil or wing. It expresses the efficiency of lift production by relating the lift force to the dynamic pressure of the airflow and the reference area of the object. It enables a standardized comparison of the lift performance of different aerodynamic profiles, allowing engineers to assess and optimize aircraft components independently of their size or velocity. The formula to Calculate Normal force coefficient as follows:
where:
- is the Normal Force Coefficient,
- is the normal force (lift) in N,
- is the dynamic pressure in pa, and
- is the reference wing area in m2.
