11493 - Aircraft and Aerospace Design

Learning outcomes

Aim of the course is:
- to introduce the fundamental concerns about the representation of parts and assemblies related to aerospace and industrial engeneering,
- to expertise the student in reading and understanding technical drawings according to standards and ISO rules -
- to expertise the student in the classification of materials and parts used in aerospace vehicles, components and plants.

Course contents

Papers and instruments for design and drawings. Standard lines; inscriptions; basic geometrical constructions; rules of orthogonal projection methods; sections; cavalier and isometric perspective. Standards in technical design; type of drawing: parts, assembly, installation, exploded, for manufacturing. Technological tests and materials classification. Applications and nomenclature of materials used in aerospace: steel, alluminum, magnesium, titanium, composite materials (glass, carbon, kevlar fibres); thermal processing. Standard numbers; Renard series; dimensional and geometrical tolerances; roughness; micro and macro geometrical errors. Joints; threaded connections; hot and cold riveting; shaft-hub joints; conical elements joints; other joints; articulated joints and guide. Llubrication methods. Plain bearings; rolling bearings; bearings assemblies; seal systems. Elastic and rigid joints; transmissions with belts and pulleys; friction wheels, gears; worm gears and cam. Nomenclature of airfoils and drawing of the NACA airfoils. Drawing of propellers. Applications of lofting techniques to fuselage drawing. Drawing of components and structures for aerospace: spars, ribs, stringers, frames, engine mountings, parts and components of aircrafts, helicopters, blimps and airships, hot air balloons, satellites. Short notes on ergonomy: drawing of the pilot and passenger size in the cabin. Short notes on rapid prototyping and reverse engineering. Basic concepts of Computer Aided Design (CAD).
