ECTS credits: 6
Acquiring fundamental knowledge of aircraft aerodynamics and flight mechanics essential for training to work in the field of aircraft exploitation and maintenance.
Fundamentals of aerodynamics: equations of state, conserving mass and motion quantity, the first law of thermodynamics, equation of isentropic flow, energy equation, speed of sound, isentropic flow, supersonic flow, nozzles. Friction drag: laminar, turbulent and mixed boundary layers. Thin airfoil at a small angle of attack: geometry, aerodynamic coefficients, incompressible flow, asymmetric airfoil, airfoil database, impact of compressibility, superposition principle, critical Mach number, supercritical airfoil. Supersonic flow: Mach cone, aerodynamic coefficient of a panel. Finite wing: geometry, influence of tips, lift, induced drag, flaps and slats, control surfaces. Fuselage. Static stability, lift, pitching moment, steady flight, static stability, neutral point, mass centre limits, yawing moment, free elevator influence on the neutral point, joystick force. Level flight: flight attitude, required force (power), available force (power), envelopes, range (propeller and jet power plants), flight duration (propeller and jet power plants). Climbing: BRC and BAC, climbing and fuel consumption time. Descending: range and angle. Level turn: turn radius and rate, load factor. Vertical turn: turn radius and rate, load factor. Take-off and landing: take-off procedure, rolling and take-off lengths, description of landing, descending, braking. Total energy: energy height, aircraft specific power, the scope of aircraft use. Aircraft performance testing: measurement accuracy, preparation and reporting, ground measurements (theodolitic and radar), on-board measurements (speed, angle of attack and temperature). Experimental setting of the polar star, BRC, lift stall. Take-off and landing tests.
Acquired basic knowledge in the field of aerodynamics and flight mechanics applicable to the field of aircraft maintenance. Competence for flight scheduling in the performance department of an airline company.
