Of Helicopter Flight - Principles

A pilot manages these forces using three main inputs that adjust the of the rotor blades: Principles Of Helicopter Aerodynamics - ftp.arcchurches.com

: In forward flight, the "advancing" blade (moving with the flight direction) experiences higher relative wind speed than the "retreating" blade. This creates unequal lift across the rotor disc, which is balanced by blade flapping , allowing blades to move up and down to equalise lift. Primary Flight Controls Principles of Helicopter Flight

: Helicopter blades are airfoils that create lift by moving through the air. According to Bernoulli’s Principle , air moves faster over the curved top surface, creating a low-pressure zone, while slower air underneath creates a high-pressure zone that pushes the blade upward.
