Presentation Transcript

  1. BASIC AERODYNAMICS

  2. Aerodynamic Terms • Angle of Attack Angle Between Chord Line & Relative Wind • Relative Wind The direction of the airstream in relation to the airfoil

  3. Aerodynamic Terms • Lift • Is the force that acts in an upward direction to support the aircraft in the air. It counteracts the effects of weight. Lift must be greater than or equal to weight if flight is to be sustained. Lift acts perpendicular to relative wind • Weight • The force of gravity acting downward on • the aircraft and everything in the aircraft, such as fuel and cargo.

  4. LIFT WEIGHT

  5. Aerodynamic Terms • Drag Parallel & Opposite to Relative Wind • Total Aerodynamic Force Vector Sum of Airfoil Lift & Drag

  6. TAF LIFT DRAG WEIGHT

  7. Drag • Types of Drag • Induced: Caused by the Production of Lift • Parasite: All Drag Not Caused by Lift

  8. Airfoil Force Vectors

  9. Airflow
