4. Higher Education Aviation Programs in Greece: A Missed Opportunity or a Challenge to Meet?
Abstract: The air transport industry in Greece has been experiencing a significant growth. However, higher education has missed so far this export opportunity. Public universities and technological educational institutes have very limited undergraduate offerings in the fields of aeronautical engineering and aircraft maintenance technology, respectively. Thes

7. Applicability of FT-IR Techniques and Goniometry on Characterization of Carbon Fiber Surfaces
ABSTRACT Carbon fibers have been widely used as structural reinforcement in aeronautical composites, because of their exceptional mechanical properties. However, carbon fibers present few polar groups on their surfaces inducing a weak interaction with some thermosetting and thermoplastic matrices. Surface treatments, such as thermal and electrochemical oxida

8. A new metamodel for reinforced panels under compressive loads and its application to the fuselage conception
This work presents a new metamodel for reinforced panels under compressive loads, typically used in light-weight aircraft structures. The metamodel represents a replicable cell structure of integrally machined panels. The presented formulation for conception is based on the synthesis of four stability criteria: section crippling, web buckling, flange bucklin

9. Evaluation of a nanostructured microwave absorbent coating applied to a glass fiber/polyphenylene sulfide laminated composite
The rapid coating of composites with absorbing paints yields materials that can absorb microwave radiation and still have approximately the same specific mass of the original composites. The use of paints with specific electromagnetic properties together with carbon- nanotube-based materials allows the production of structural materials of interest to the ae

10. Gestão de portfólio de serviços de MRO (Maintenance, Repair and Overhaul) aeronáutico: uma pesquisa ação / Portfolio management service MRO (Maintenance, Repair and Overhaul) aircraft: an action research
The aircraft maintenance centers in Latin America have limited portfolios of services; this is a factor that restricts the growth of air transport in the region. Therefore is necessary to develop new maintenance, repair and overhaul (MRO) services for aircraft and their components in those centers. New Product Development (NPD) process theory has received su

11. Uncertainty quantification of aircraft modal analysis using perturbation technique in the stochastic finite element method
Structural members, such as, stiffeners are applied to aeronautical structures in order to promote the necessary global or local dynamic stiffness. The manufacture and assembly process of these parts and machines capability can introduce variability in the parts and thereby incorporating uncertainties in the structural performance. Tolerances known as GD&T (
