BASIC AERODYNAMICS Aerodynamic Terms Angle of Attack

BASIC AERODYNAMICS Aerodynamic Terms Angle of Attack Angle Between Chord Line & Relative Wind Relative Wind The direction of the airstream in relation to the airfoil Aerodynamic Terms Drag Parallel & Opposite to Relative Wind Total Aerodynamic Force Vector Sum of Airfoil Lift & Drag Drag Types of Drag Induced: Caused by the Production of Lift Parasite: All Drag Not Caused by Lift Airfoil Force Vectors Airflow Aerodynamics * 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.
