EASA 66 Module 8 - Basic Aerodynamics
EASA 66 Module 8 covers the basics of Aerodynamics. Topics in this 53 page course include Physics of the Atmosphere, Aerodynamics, Theory of Flight, and Flight Stability and Dynamics.
- 8.1 Physics of the Atmosphere
- International Standard Atmosphere (ISA),application to aerodynamics.
- 8.2 Aerodynamics
- Airflow around a body; Boundary layer, laminar and turbulent flow, free stream flow, relative airflow, upwash and downwash, vortices,stagnation;The terms: camber, chord, mean aerodynamic chord, profile (parasite) drag, induced drag,centre of pressure, angle of attack, wash in and wash out, fineness ratio, wing shape and aspect ratio; Thrust, Weight, Aerodynamic Resultant;Generation of Lift and Drag: Angle of Attack,Lift coefficient, Drag coefficient, polar curve,stall;Aerofoil contamination including ice, snow,frost.
- 8.3 Theory of Flight
- Relationship between lift weight, thrust and drag;Glide ratio; Steady state flights, performance;Theory of the turn;Influence of load factor: stall, flight envelope and structural limitations;Lift augmentation.
- 8.4 Flight Stability and Dynamics
- Longitudinal, lateral and directional stability (active and passive).
