### Course description

The Flight Mechanics course has the scope of introducing the students to the Flight Theory and the performances of fixed wing airplanes in gliding and powered flight.
Knowledge and understanding: the student must demonstrate knowledge and understanding of the fundamentals of fluidynamics, flight theory and main performance of fixed wing airplanes.
Ability to apply knowledge and understanding: the student must demonstrate the ability to use his acquired knowledge to know more the subjects of the aeronautical route.
Autonomy of judgement: the student should be able to assess independently the results coming from his own learning process.
Communication skills: the student should be able to draw up a report about the studied subjects.
Learning skills: students must be able to update and deepen topics about flight theory and performance of fixed-wing aircrafts.

### Prerequisites

The student has to understand algebra, Mathematics first module and Phisics first module

### Syllabus

- Aircraft classification - Aerodynamic lift - aircraft configurations: wing. fuselage, tails, control surfaces – Fluidynamics
Principal fluids properties - Equilibrium - Atmoshpere laws - The International standard Atmosphere - State equation. Fluids Viscosity: the boundary layer and the Reynolds number: laminar and turbulent boundary layer - Transition and separation of boundary layer Fluids compressibility : The sound speed - Shock waves
Applied aerodynamics
The finite wing: the induced drag. The Oswald' efficiency factor - The wing drag polar - Leading and trailing edge flaps - The complete airplane drag polar - Build-up method - The interference drag - The aerodynamic efficiency - Main points of complete airplane drag polar
The propeller - Nomenclature and functioning
The speed measurement on the aircraft: the pitot tube - IAS, CAS, EAS, TAS.
Introduction to the Flight Mechanics
The level and uniform flight: speeds, thrust, power requested. Aeronautical propulsion: available thrust and power: propeller and jets and their variation with altitude– Comparison between requested and available thrust and power - Minimum and maximum speeds - Ceiling
The climbing flight- Rate of climb - steepest and fast climb - Optimal conditions for propeller and turbojet
The descent and gliding flight– Range and endurance: typical points - The odograph curve in gliding flight - the wind influence on gliding flight- air and ground speeds.
The maneuvering flight: acceleration and load factor - True and apparent weight– The normal loads factor and its limitations - The gust diagram - The turning flight : equations, requested speed, thrust, power ; load factor and its limitations. Minimum turn radius - The standard turn - Maneuver speed
The pull-up maneuver: motions law -
The take-off maneuver: ground and air segments - The motion law - Typical speed in take-off - Decision – Take-off distance calculation - Optimum angle of attack during take-
The landing maneuver: air and ground segment - The motion law - Landing distance evaluation .
The fuel consumption, range and endurance of the airplanes - The Breguet formulas -

### Teaching Methods

Frontal lessons (50 hours) – Laboratory (16 hours) – Educational visits (6 hours). The lessons are actually held in Italian.

### Textbooks

- Lecture notes available on intranet
- V. Losito: Fondamenti di Aeronautica Generale
- Anderson, Jr, Introduction to flight
- A.C. Kermode: Mechanics of Flight.

### Learning assessment

The examination consists of an oral test: the student presents and analizes a paper prepared by himself that contains the study and the evaluation of the performance of an aircraft. Some questions about the main topics of the corse follow.
