ATTITUDE TEST [7 records]

Record 1 2004-06-08

English

Subject field(s)
  • Orbital Stations
  • Research Experiments in Space
CONT

The European Technology Exposure Facility (EuTEF) is a programmable, multifunctional, fully automated system. The modular architecture provides uniform interfaces for instruments - up to seven instrument modules can be accommodated and operated simultaneously.

CONT

... the Technology Exposure Facility will [be used to] test superconductor systems destined for satellite communications. These systems will provide power saving and enhanced performance. The module will also be testing electric propulsion for communications systems for orbital transfer manoeuvering, station keeping and attitude control.

OBS

European technology exposure facility; EuTEF: term and abbreviation officially approved by the International Space Station official approval Group (ISSOAG).

Subject field(s)
  • Applications of Electronics
  • Aircraft Piloting and Navigation
  • Navigation Instruments
  • Flight Instruments and Equipment (Aeroindustry)
CONT

Ultra-sensitive accelerometry for space applications... The accelerometers developed are based essentially on the idea of electrostatic levitation of an inert test mass in the center of a cage... having particularly well-defined electric qualities. The position and attitude of the mass are measured by capacitive detectors. These measurements are used, with electronic slaving loops, to apply voltages to a set of electrodes distributed around the test mass.

  • Instruments de navigation
  • Instruments et équipement de bord (Constructions aéronautiques)
CONT

Lorsqu'il est lié par la centrale directement à l'avion, le gyroscope doit être complété par une boucle électronique d'asservissement (boucle gyrométrique) qui fait précessionner son rotor de manière à lui faire suivre les mouvements angulaires de l'avion. La commande de précession est proportionnelle à la vitesse angulaire et constitue donc une mesure de celle-ci.

Subject field(s)
  • Bearings and Bearing Systems (Mechanical Components)
  • Navigation Instruments

  • Ship Piloting
CONT

SIMSAT-The AFIT spacecraft simulator, a three-axis 200 lb. Testbed supported on a spherical air bearing. Capable of simulating three-axis rotational maneuvers of satellites. The Tri-Axis Spherical Air Bearing is a custom spin test machine which uses a spherical gas bearing to achieve a low friction support system with three rotational degrees-of freedom for use in testing cold gas attitude control systems(ACS) of small and large space vehicles. The Air Bearing System consists primarily of a highly polished ball on a stiff shaft, constituting a rotor assembly, which floats on a film of compressed gas. The rotor assembly supports objects weighing up to 300 pounds.

OBS

gas bearing. A journal or thrust bearing lubricated with gas. Also known as gas-lubricated bearing.

CONT

Gyroscope [...] Le corps solide en rotation est supporté dans son carter par l'intermédiaire de deux paliers à roulements à billes ou quelquefois à gaz assurant la liberté de la rotation du gyroscope autour de son axe de révolution. [...] Les paliers à gaz sont maintenant très répandus dans les matériels de navigation par inertie pour avions et navires. Ils sont de plusieurs types : sphériques, coniques, cylindriques.
