Module 8. Basic Aerodynamics (Part-66)

Content: Part-66 Module 8. Basic Aerodynamics

1. Physics of the Atmosphere

• International Standard Atmosphere (ISA), application to aerodynamics.

2. Aerodynamics

• Airflow around a body;
• Boundary layer, laminar and turbulent flow, free stream flow, relativeairflow, 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 washout, fineness ratio, wing shape and aspect ratio;
• Thrust, Weight, Aerodynamic Resultant;
• Generation of Lift and Drag: Angle of Attack, Lift coefficient, Dragcoefficient, polar curve, stall;
• Aerofoil contamination including ice, snow, frost.

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.

4. Flight Stability and Dynamics

• Longitudinal, lateral and directional stability (active and passive).
