Subject field(s)
  • Refrigerating Machines and Appliances
  • Flight Instruments and Equipment (Aeroindustry)
CONT

Air-cycle refrigeration systems ... are used in many modern commercial aircraft for air-conditioning the cabin. ... The compressed air, when expanded in an expander turbine, drops enough in temperature to be used to chill the cabin air. Such a system for aircraft is effective and lightweight because it makes use of air already compressed by the power compressors.

French

Domaine(s)
  • Machines frigorifiques
  • Instruments et équipement de bord (Constructions aéronautiques)
DEF

Machine frigorifique utilisant la détente de l'air préalablement comprimé.

CONT

[...] Comprimé, [l'air] subit un refroidissement à pression constante, puis est détendu dans une machine à turbine [...] On utilise aussi la machine frigorifique à air pour le conditionnement d'air des avions, parce qu'elle est légère et compacte.

OBS

La distinction que le «Nouveau dictionnaire international du froid» (DIFRA) établit entre les termes «machine», «système» et «installation» est intéressante, mais la plupart des sources consultées les emploient l'un pour l'autre.

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.

Key term(s)
