Introduction to Aerodynamics
The four forces
-Lift
-Weight
-Thrust
-Drag
Airfoils
-Symmetrical vs. Asymmetrical
-Leading edge
-Trailing edge
-Chord line
-Relative wind
-Angle of attack
-Bernoulli's Principle
-Tip path plane
Factors affecting lift and drag
-Surface area
-Angle of attack
-Velocity of airflow
-Air density
-Blade stall
The three axes
-Longitudinal/Roll
-Lateral/Pitch
-Vertical/ Yaw
Torque
-Newton's third law of motion
-Tail rotor thrust
-Controlling torque
Rotor systems
-Fully articulated
-Semi-rigid
-Rigid
Vibrations
-Resonance; sympathetic, ground resonance
-Low frequency vibrations
-Medium frequency vibrations
-High frequency vibrat
