Abstract

International audience; Civil high-speed passenger transport only makes sense when deployed for long-haul intercontinental flights. Consequently, the related development and deployment of such a high-speed vehicle will most likely demand an international approach. The internationally funded HEXAFLY-INT project is a first step in the direction of civil high-speed transportation along with an international development where flighttesting is the focal point. The global aim is to flight test an experimental waverider-based vehicle concept above Mach 7 to verify its potential for a high cruise efficiency during a free-flight. In parallel, the concept will also be flight tested to prove the waverider concept is also able to take-off, to accelerate to subsonic speed and to land in an efficient and robust way. The feasibility for a 3m long vehicle was demonstrated during the European precursor project HEXAFLY. Its realization is now being enabled on an international scale preparing the grounds for global cooperation in case of a future deployment of a high-speed cruiser. These flight opportunities will increase drastically the Technology Readiness Level of developments realized in previous high-speed EC projects such as ATLLAS I & II and LAPCAT I & II. The present paper describes the various numerical and experimental investigations carried out so far by the different international partners.

Abstract

National audience; The displays used by the air traffic controllers involve many animated visual entities. They are constrained by precise rules of representation. The richness of these representations highlights the lack of tools that may characterize them. The increments of such an instrument are numerous, in terms of validation, design and safety. The objective of the thesis is to study representations, to find out methods of characterization that would allow comparisons between representations, and eventually to check their interests.; Les images utilisées par les contrôleurs aériens comportent de nombreuses entités visuelles animées.Elles sont soumises à des règles de représentation précises.La richesse de ces représentations a mis en évidence l’absence d’outils permettant de les caractériser.Les incréments d’un tel instruments ont multiples, en termes de validation, de design et de sécurité.L’objectif de la thèse est d’étudier des représentations,de trouver des méthodes de caractérisation afin notamment de permettre des comparaisons entres vues et de vérifier leur intérêt.
