Reasonaly coefficeint of lift

In fluid dynamics, the lift coefficient (CL) is a dimensionless quantity that relates the lift generated by a lifting body to the fluid density around the body, the fluid velocity and an associated reference area. A lifting body is a foil or a complete foil-bearing body such as a fixed-wing aircraft. CL is a function of the angle of the body to the flow, its Reynolds number and its Mach number. The section lift coefficient cl refers to the dynamic lift characteristics of a two-dimensional foil section, with t… Webb18 sep. 2024 · Because an aircraft in level flight is in equilibrium with gravity, a sudden reduction in lift can have a dramatic effect. A rapid sink and nasty shuddering as stall turbulence rocks the aircraft. However, checking the lift to AOA curve shows the plane still has significant lift in stall, but not enough to match gravity.
