Study Notes
Aerodynamics of Flight
Four Forces of Flight
- Lift: upward force opposing weight, created by wing shape and airfoil
- Weight: downward force, opposing lift, resulting from aircraft mass
- Thrust: forward force, opposing drag, generated by propellers or jets
- Drag: backward force, opposing thrust, resulting from air resistance
Wing Aerodynamics
- Airfoil: curved surface of wing, deflecting air downward to create lift
- Cambered: curved upper surface, increasing lift
- Symmetrical: flat upper surface, used for high-speed flight
- Angle of Attack: wing's angle relative to oncoming airflow, affecting lift and drag
Bernoulli's Principle
- Pressure: inversely proportional to airspeed
- Lift: created by lower pressure above wing, higher pressure below
Airfoil Components
- Leading Edge: front of wing, influencing airflow
- Trailing Edge: rear of wing, affecting lift and drag
- Chord Line: imaginary line connecting leading and trailing edges
Wingtip Vortices
- Wingtip Vortices: rotating air masses at wingtips, creating drag
- Winglet: vertical extension at wingtip, reducing vortices and drag
Four Forces of Flight
- Lift is an upward force that opposes weight, created by the wing's shape and airfoil.
- Weight is a downward force that opposes lift, resulting from the aircraft's mass.
- Thrust is a forward force that opposes drag, generated by propellers or jets.
- Drag is a backward force that opposes thrust, resulting from air resistance.
Wing Aerodynamics
- An airfoil is the curved surface of the wing that deflects air downward to create lift.
- A cambered airfoil has a curved upper surface that increases lift.
- A symmetrical airfoil has a flat upper surface, used for high-speed flight.
- The angle of attack is the wing's angle relative to oncoming airflow, affecting lift and drag.
Bernoulli's Principle
- Pressure is inversely proportional to airspeed.
- Lift is created by lower pressure above the wing and higher pressure below.

- The leading edge is the front of the wing, influencing airflow.
- The trailing edge is the rear of the wing, affecting lift and drag.
- The chord line is an imaginary line connecting the leading and trailing edges.
Wingtip Vortices
- Wingtip vortices are rotating air masses at the wingtips that create drag.
- A winglet is a vertical extension at the wingtip that reduces vortices and drag.
