Downwash
In aeronautics downwash is the air forced down by the aerodynamic action of a wing or helicopter rotor blade in motion, as part of the process of producing lift.[1]
An aircraft produces aerodynamic lift by deflecting air downwards as downwash. This generates an equal and opposite upwards force on the wing called lift. When the downwash force exceeds the weight of the aircraft, the aircraft will rise.[1][2][3]
