Study Notes
Aerodynamics
- The deflection of air by an airfoil, wing, or helicopter rotor blade in motion is known as deflection.
Angle of Attack
- The angle between the oncoming air or relative wind and a reference line on the airplane or wing is called the angle of attack.
Newton's Third Law
- For every action, there is an equal and opposite reaction.
Venturi Shape
- The shape of a venturi is similar to a funnel.
Aerodynamic Lift and Drag
- The shape of an airfoil determines the aerodynamic lift and drag.
Airfoil Shape
- The shape of a subsonic airfoil is typically curved on top and flat on the bottom.
Airfoil Shape and Aerodynamic Lift and Drag
- The shape of an airfoil affects the aerodynamic lift and drag, with the curved top surface creating lift and the flat bottom surface creating drag.
Angle of Incidence
- The angle at which the wing is attached to the fuselage is called the angle of incidence.
Lift Production
- The process of producing lift through the change in direction of air deflected by an airfoil, wing, or helicopter rotor blade is called lift production.
