Record 2 2003-08-18

English

Subject field(s)
  • Launching and Space Maneuvering
CONT

The Local Vertical Local Horizontal coordinate system is referenced to the near-circular orbital plane. In order to specify the attitude of the Station with respect to the Local Vertical Local Horizontal, a system based on Eulerian angles of roll, pitch and yaw is used.

CONT

The ISS [International Space Station] flies in an attitude that is referenced to the orbital plane of ISS using a set of local vertical/local-horizontal axes. The origin is at the ISS centre of mass, with the x-axis pointing along the direction of the orbital velocity vector(sometimes referred to as the "ram" direction). The z-axis points directly towards the Earth, and the y-axis parallel to the truss assembly... This orientation is referred to as "x-axis toward the velocity vector" Torque Equilibrium Attitude and is the "normal" orientation of the ISS. The overall ISS design is optimised to fly in this attitude, which places the most laboratory modules in the "best" microgravity volume, supports attitude reboosts, service vehicle docking and minimises aerodynamic drag.

OBS

local vertical local horizontal; LVLH: term and abbreviation officially approved by the International Space Station official approval Group (ISSOAG).

French

Domaine(s)
  • Lancement et manœuvres dans l'espace
OBS

local vertical local horizontal; LVLH : terme et abréviation uniformisés par le Groupe de travail de la terminologie de la Station spatiale internationale (GTTSSI).

Subject field(s)
  • Aeroindustry
CONT

For aerodynamic testing, CEAT [Centre d’essais Aéronautique de Toulouse] has two subsonic wind tunnels designated S4 and S5. The S4 tunnel can take test models of up to 2. 4 m(8ft) span and the airspeed can reach as much as 40 m/sec. It is equipped with a Denis-Gruson balance with profiled supports and a real time system for the acquisition and processing of test parameters.

OBS

mock-up: term officially approved by the International Civil Aviation Organization (ICAO).

Domaine(s)
  • Constructions aéronautiques
CONT

Essais aérodynamiques. Pour les essais de ce genre, le CEAT [Centre d'essais Aéronautique de Toulouse] dispose tout d'abord de deux souffleries subsoniques, S4 et S5. La première peut recevoir des maquettes de 2,4 m d'envergure, la vitesse pouvant atteindre 40 m/s. Elle est équipée d'une balance Denis-Gruson à mâts profilés et d'une chaîne d'acquisition et de traitement des paramètres en temps réel.
