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
Longitudinal Aerodynamic Forces
Circulation of Incompressible Air FlowAbout a 2-D Airfoil
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
What Do We Mean by 2-Dimensional Aerodynamics?
Effect of Sweep Angle on Lift
Typical Airfoil Profiles
