Thermophysical properties of a carbon-reinforced epoxy composite laminate (T700/M21 composite for aircraft structures) were evaluated using different innovative characterisation methods. Thermogravimetric Analysis (TGA), Simultaneous Thermal analysis (STA), Laser Flash analysis (LFA), and Fourier Transform Infrared (FTIR) analysis were used for measuring the thermal decomposition, the specific ...

Optical fiber based Extrinsic Fabry-Perot Interferometric (EFPI) sensor significantly emerged as an advanced optical sensor for the health monitoring of civil, mechanical and aeronautical structures. This sensor responds its well capability also towards the measurement of acoustic/shock wave pressure. This paper presents an approach for high blast (acoustic/shock wave) pressure measurement usin...

This paper proposes a reliable system to overcome the weakness of current the HF radio communication system for oceanic aeronautical flight routes. This system uses only one aeronautical VHF channel with air-toair radio relay system based on local mobile Ad-hoc networks. For access to/from all aircrafts in the system, a TDMA (Time Division Multiple Access) scheme is proposed to be used where ea...

The permanent growth of air traffic volume, being a main contributor to economic growth, is reaching the limits of what current Air Traffic Management (ATM) systems are capable to handle. Fundamental changes in ATM operations are required to cope with the expected increase in the next decades. On one hand, the bottleneck of centralized control of air space operations has been identified as a co...

Aspects of a draft version of the Aeronautical Telecommunications Network (ATN) Standards and Recommended Practices (SARPs) under development by ISO-compliant committees of the International Civil Aviation Organization (ICAO) have been mathematically modelled using a formal description technique. The ATN SARPs are a specification for a global telecommunications network for air traffic control s...
