Video Details

Codename: Afterburnpower

The National Police of the Netherlands is vigilant and subservient to the values of the constitutional state. Working on the safety of society, tackling crime and protecting and helping citizens are key priorities for the police. 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 Newton's third law of motion - the force required to create the downwash is equal in magnitude and opposite in direction to the lift force on the airfoil. Lift on an airfoil is also an example of the Kutta-Joukowski theorem - the Kutta condition explains the existence of downwash at the trailing edge of the wing.
