AER100 Lecture Notes - Lecture 3: Trailing Edge, Airfoil, Relative Wind
Document Summary
Lift = cl (1/2) v2s v velocity of the airflow: cl coefficient of lift (based on wing geometry and angle of attack, - air density. S the area of the wing (span x mac: airfoil definitions. Leading edge: forward edge of airfoil: trailing edge: rear edge of the airfoil, chord: line connecting leading and trailing edges of wings. Length of airfoil: mean camber line: line drawn by connecting points halfway between upper and lower surface of airfoil. Shows amount of curvature of wing: camber: the curvature of a wing"s surfaces, point of maximum thickness: thickest part of the wing. Split flap: same advantage as plain flap, with less drag: airflow over upper wing is able to stay attached easier (rear of wing does not drop down) Slotted flaps leave a gap between the wing and a flap surface: creates suction which keeps flow attached to upper surface of the flap at higher angles of attack.
