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. Lift on airfoil is an example of application of the law of conservation of momentum - the force required to create the downwash is equal in magnitude and op...

A term applied to airstream deflected downwards behind a lifting aerofoil. The angle of downwash is the angle of the inclined airstream relative to the longitudinal axis of the aeroplane. The downwash behind the mainplane may have an important influence on the tailplane.
