Helicopter Rotor Wash Velocity at Jason Liller blog

Helicopter Rotor Wash Velocity. as a summary: in aeronautics, downwash is the change in direction of air deflected by the aerodynamic action of an airfoil, wing, or helicopter rotor blade in motion, as part of the process of producing lift. When hovering out of ground effect at greater than 1 rotor diameter, rotor downwash dissipates into the surrounding air without. If you want a lower downwash velocity, you need a helicopter with a low mass, and a massive rotor diameter. based on conservation of mass and momentum principles it may be shown that the maximum theoretical downwash velocity is twice the initial vi. Rotorcraft brownout is caused by the entrainment of dust and sand particles in helicopter downwash, resulting in reduced pilot visibility during low, slow flight and. the calculated downwash velocities for a helicopter with a 22m rotor diameter with a mass of 13t and 18t is shown in figure 3 where it can be seen that the 80km/h wind velocities are exceeded at up to 40m from the rotor diameter (this would require an 80m wide corridor). The opposite does exist however: the velocity of the downwash reaches a maximum about 2 rotor diameters below the disc.
