Helicopter Dynamics topics include: Helicopter rotor and its notations, momentum theory, helicopter blades propellers, blade element theory, combined blade element and momentum theory.
Helicopter dynamics is a field of aerospace engineering that includes theoretical and practical aspects of helicopter flight.
It includes: Aerodynamics, Stability, Control, Structural dynamics, Vibration, Aeroelastic and aeromechanical stability.
Helicopters have two rotors, the main rotor and the tail rotor. The main rotor blades are attached to the engine and rotate against the surrounding air to produce a flow along each rotor blade. The main rotor produces lift and thrust, and the tail rotor compensates for the torque generated by the main rotor. Helicopters are affected by the same four forces that planes are: Lift, Weight, Drag, Thrust. Helicopters also have some unique aerodynamic principles, including: Dissymmetry of lift: The blades are spinning in a circle as the aircraft moves forward Gyroscopic precession: The effects of any input which is made will take place 90-degrees later
