Chord: The Length of a Wing Parallel to the Direction of Motion

The chord of a wing refers to the measurement of its length in a direction parallel to the direction of motion. It is the distance between the leading edge and the trailing edge of the wing, passing through the wing’s profile. In simpler terms, it is the straight line that connects the two endpoints of the wing. The chord is an essential component in determining the wing’s aerodynamic properties, such as lift and drag.

The chord should not be confused with the wing’s span, which refers to the measurement of its length perpendicular to the direction of motion. Thickness is another dimension that should not be mistaken for chord. The thickness refers to the distance between the upper and lower surfaces of the wing.

The chord of a wing plays a crucial role in its aerodynamic performance. The size and shape of the chord determine the amount of lift and drag the wing can generate. Therefore, wing designers carefully select the size and shape of the chord to ensure that the wing is efficient in flight.

In summary, the chord is the length of a wing parallel to the direction of motion. It is a vital component in determining the wing’s aerodynamic properties and should not be confused with the span or thickness of the wing. Its size and shape are crucial in ensuring that the wing is efficient in flight.
