### Course description

The course aims to inform students about the behavior of fixed-wing aircraft in terms of motion around the center of gravity, addressing the aspects related to the various cases of static and dynamic stability.

### Prerequisites

The students need to know the principles of Flight Mechanics, Mathematics, Computer Science and a good knowledge of "Mathlab".

### Syllabus

Summary of the main topics related to aircraft performance: level flight, climbing flight, gliding flight, maneuvering flight, load factor, turning flight, pull-up maneuver, take off, landing, range and endurance.
Static stability and control - Longitudinal stability and control with stick-fixed: contribution of the airplane parts; rear neutral point of stability - Longitudinal control - Thrust effects - Center of gravity range - Longitudinal static stability and control with stick free - Hinge moment and floating - Rear neutral point of stability with stick free - The trim-tab - Stick force and its reduction - Maneuvering flight
Latero-directional static stability and control - Contribution of the airplane parts - Thrust effects - The directional control - Lateral Stability with stick-fixed - The lateral control - Approximate equations of latero-directional motion - Directional Stability with stick-free - Stick force and ailerons balancing.
Airplane equations of motion - Axes reference systems - Euler' angles - coordinate systems transformation - Equations of motion linearization - Longitudinal and latero-directional aerodynamic derivatives. 5) Longitudinal dynamics - Characteristic equation in longitudinal plane and system eingenvalues - Longitudinal stability criteria - Phugoid and short-period modes - Lateral-directional stability criteria:spiral, divergent, dutch-roll modes - Root Locus

The course includes the study of the static and dynamic stability of fixed wing aircraft with physical and analytical insights

### Teaching Methods

Frontal lessons (7 CFU: 56 hours); exercises and laboratory (2CFU: 16 hours)

### Textbooks

) From the book: "Fondamenti di Aeronautica Generale" by Valentino Losito,
Lecture notes by Giuseppe Del Core, available in intranet

### Learning assessment

The examination consists of a oral test in which the student introduces and discusses a paper prepared by himself, containing the analysis of an aircraft stability ducted by matlab and simulink. Other questions about the main topics of the course follow.
