The environmental impact and the dependence upon fossil fuels in aeronautical sector have promoted demand for alternative greener fuels. implementation of is one o...

Automatic storage management, or garbage collection, is a feature usually associated with languages oriented toward "symbolic processing," such as Lisp or Prolog; it is seldom associated with "systems" languages, such as C and C++. This report surveys techniques for performing garbage collection for languages such as C and C++, and presents an implementation of a concurrent copying collector fo...

This paper presents a networking testbed, which is developed within the EC FP7 project SANDRA to test and validate IPv6-based protocols for future Air Traffic Management (ATM) network. The development was originally initiated within the EC FP6 project NEWSKY which aimed at developing a concept for a global, heterogeneous communication network for aeronautical communications, based on IPv6 proto...

Air Traffic Management (ATM) is evolving towards integration of all its parts into a global system-wide information management system for information sharing and collaborative decision-making. It would be useful to evaluate new technologies that would help in the integration of these large, heterogeneous, distributed, and often old ATM systems. The objective of this poster-paper is to introduce...

Abstract Aluminum-Scandium alloys offer a great potential in aerospace applications due their high corrosion resistance and improved strength properties. Furthermore, these have been qualified for laser additive manufacturing (AM), producing parts with static strengths rivalling conventionally manufactured counterparts. However, processing also results large residual stresses that can severely ...

The demonstration of compliance aeronautical structures with certification requirements is generally based on the building block approach, considering tests from coupon level up to full-scale level. Coupon-scale are numerous and focused uniaxial loading target elementary failure modes, whereas submitted complex combined loadings, leading costly test campaigns thousands coupons. This paper consi...

The US airspace is reaching its capacity with the current Air Traffic Control system and a number of flights that is constantly rising, and estimated to be over 54 million per year by 2002. The FAA has undertaken several projects to modernize the National Airspace System (NAS) to ensure the safety of the increasing number of flights. Of special importance is the modernization of the Air-Ground ...
