Aerodynamics
This document discusses the key aerodynamic forces that act on aircraft in flight - lift, thrust, drag, and weight. It explains lift is generated by the angle of attack and lift coefficient, and how drag consists of parasite drag from friction and induced drag from creating lift. The document covers drag curves and how drag and power vary with velocity, with implications for maximum power and drag speeds. Stalls during flight are examined along with extensions like spins. The document also briefly lists additional aircraft design topics.

Editor's Notes
- #4 ρ = 1.225 kg/m3S example values: 747-400 = 525m2,Cessna 152 = 15m2V = true airspeed
- #9 D = Total drag
- #10 CD0 = Zero lift drag coefficientCDi = Induced drag coefficientCD0 is the sum of the drag coefficients for all wetted components on the airframe
- #19 Minimum drag = best lift to drag ratio
