Low-Speed Aerodynamics

2-Dimensional AerodynamicLift and Drag

Lift dan Drag • Lift adalah tegak lurus terhadap arah aliran free-stream • Drag adalah parallel terhadap arah aliran free-stream

Relationship BetweenCirculation and Lift

Lift vs. Angle of Attack

Typical Flow Variationwith Angle of Attack

• At higher angles, – flow separates – wing loses lift

• Flow separation produces stall
