This is because a helicopter generates its own gusty air while in a hover, which acts against … WebDefinition. Autorotation is a condition of helicopter flight during which the main rotor of a helicopter is driven only by aerodynamic forces with no power from the engine. It is a manoeuvre where the engine is disengaged from the main rotor system and the rotor blades are driven solely by the upward flow of air through the rotor.

WebCourse Introduction. This course provides an in-depth look at helicopter flight and rotor aerodynamics. As seen in Figure i-2, there are four forces acting on a helicopter in flight: Lift - The upward force created by the effect of airflow as it passes around an airfoil. Weight - Opposes lift and is caused by the downward pull of gravity. WebConing is a phenomenon which affects helicopter rotor discs. The tips of the helicopter rotor blades move faster through the air than the parts of the blades near the hub, so they generate more lift, which pushes the tips of the blades upwards.This is balanced by centrifugal force, resulting in a slight cone shape to the rotor disc. If rotor RPM drops too …
