In aeronautics, the chord is an imaginary straight line joining the leading edge and trailing edge of an aerofoil. The chord length is the distance between the trailing edge and the point where the chord intersects the leading edge. The point on the leading edge used to define the chord may be the surface point of minimum radius. For a turbine aerofoil the chord may be defined by the line between po… WebFeb 11, 2024 · The reduced frequency is defined as k = ωc/(2U ∞), where ω is the circular frequency of oscillation ω = 2πf, f being the frequency in Hz, c is the wing chord, including the flap chord and U ∞ is the free stream speed. The instantaneous flap angle is β (in degrees) and half amplitude of the flap oscillation is denoted by the angle β 0. iowa fb recruits https://mickhillmedia.com
