1.2 — Airfoils, Pressure & Lift Generation

Key insights

Key ideas from this lesson:

• An airfoil is defined by chord, camber and thickness — geometry sets its lift character.
• Lift comes from a pressure difference: lower average pressure above, higher below.
• Lift = ½ ρ V² S C_L — speed and angle of attack are the pilot-controllable levers.
• Beyond the critical angle of attack the flow separates and the wing stalls.
