Module 8-Basic Aerodynamics

REGULATION (EU) 2023/989
8.1 Physics of the atmosphere
International Standard Atmosphere (ISA), and its 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, and 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 High-speed airflow
Speed of sound, subsonic flight, transonic flight, supersonic flight, Mach number, critical Mach number, compressibility buffet, shock wave, aerodynamic heating, area rule;
Factors that affect airflow in engine intakes of high-speed aircraft;
Effects of sweepback on critical Mach number.
8.5 Flight stability and dynamics
Longitudinal, lateral, and directional stability (active and passive).
