Reference chord of the wing calculator

In flight mechanics and aeronautics, the “reference chord” of a wing refers to a specific chord length used as a standard measurement for the wing’s size and aerodynamic characteristics. The chord of a wing is the straight-line distance between the leading edge and the trailing edge of the wing, measured along the chord line.

Re=Vcref/v​​

where:

• $Re$ is the Reynolds number (dimensionless).
• Vcref​ is the reference velocity of the flow (usually the freestream velocity in aerodynamics).
• $v$ is the kinematic viscosity of the fluid
