It is a common emergency procedure taught to helicopter pilots as part of their training. In normal powered helicopter flight, air is drawn into the main rotor system from above and forced downward, but during autorotation, air moves into the rotor system from below as the helicopter descends.
In helicopter aerodynamics, the Lock number is the ratio of aerodynamic forces, which act to lift the rotor blades, to inertial forces, which act to maintain the blades in the plane of rotation. [1] It is named after C. N. H. Lock, a British aerodynamicist who studied autogyros in the 1920s. [2] [3]: 267

Law 1. A body continues in its state of rest, or in uniform motion in a straight line, unless acted upon by a force. Law 2. A body acted upon by a force moves in such a manner that the time rate of change of momentum equals the force. Law 3. If two bodies exert forces on each other, these forces are equal in magnitude and opposite in direction.
