Géométrie des éprouvettes : - longueur 100 à 120 mm. - éprouvettes cylindriques : diamètre des queues compis entre 16 et 20 mm, zone active de section circulaire et diamètre au choix. - possibilité d'adapter des éprouvettes parallélépipédiques. Chargements possibles : Flexion ou torsion ou flexion-torsion combinées : - essais monotones: un ou plusieurs blocs programmés définis par une consigne de départ, une consigne d'arrivée et une durée (consignes en moments). - essais cycliques de fréquences comprises entre 1 et 60 Hz : un ou plusieurs blocs programmés définis par leur durée (nombre de cycles) et la fréquence, l'amplitude, la valeur moyenne et la phase de chaque moment. - essais "pseudo-aléatoires" : l'évolution temporelle des moments est telle que sa décomposition en série de Fourier a une fréquence fondamentale comprise entre 10 et 60 Hz ; l'harmonique de plus haut rang ne doit pas dépasser 60 Hz. La forme du signal est asservie en continu. Possibilité de programmer des blocs successifs avec différents spectres de chargement. Arrêt de l'essai : - nombre de cycles. - détection de fissure: mesure de la variation de raideur de l'éprouvette (profondeur de 0.5 mm pour un diamètre actif de 10 mm).

IENA PACKET FORMAT<br />
JP.CATURLA<br />
AIRBUS INTEGRATION TEST CENTRE<br />
To increase the quality and the pertinence of the test results provided to design offices, Airbus launched<br />
the ambitious project named IENA (Installation d’Essais Nouveaux Avions = Flight test Installation for<br />
New Aircrafts)<br />
This project leads to a complete review of the acquisition, recording and data processing format.<br />
The name of the new data format defined by Airbus is ‘IENA PACKET’. The goal is to carry under one<br />
unique format all the measures provided by flight test equipments with an accurate time tagging and<br />
minimum data.<br />
This paper describes the format of ‘IENA PACKET’ which will be used as a standard by all new test<br />
installation equipments.<br />
Introduce :<br />
The IENA high level principle that led the IENA PACKET format are:<br />
- The test installation provide an unique time base (GPS or internal) to the acquisition and recording<br />
systems. All test means (flight ,ground and external) are synchronised with the same time source. A<br />
parameter is time stamped with the time of its creation<br />
- The recording data process are either continuously (Sample frequency or repetitively cycle) or on<br />
asynchronous event<br />
- Test installation means and decoder exploitation tools have one unique data stream format<br />
The next part of this article describes and emphasises all fields of the IENA PACKETS format.<br />
