English

Subject field(s)
  • Types of Aircraft
  • Weather Stations and Meteorological Instruments and Equipment
DEF

A ... balloon attached to a cable that is used to raise and lower the balloon.

CONT

Captive balloons were used for military observations in the U.S. Civil War, and now these craft can thrill passengers with unparalleled views.

OBS

In order to hold the balloon steady at a predetermined position in the sky, two methods are possible. One is to tether it by cables, and the other is to provide it with power.

OBS

A tethered balloon [may be] carrying instruments for making observations in the lower layers of the atmosphere.

OBS

Tethered balloons have been deployed from fixed locations over land and from ships.

OBS

tethered balloon: term used in Australian Civil Aviation Safety’s, Federal Aviation Administration’s, and Transports Canada’s Regulations.

OBS

In Canada, a permanently-tethered balloon system is an "aircraft" under the definition of the Aeronautics Act. Specifically, a balloon is defined as a "non-power driven lighter-than-air aircraft". Whether operating freely, under temporary tether or as a permanently-tethered unit, balloons are subject to the Canadian Aviation Regulations (CARs).

OBS

captive balloon: term used in the International Civil Aviation Organization’s and ISO’s documentation. Term opposed to "free balloon."

OBS

captive balloon: term standardized by ISO.

OBS

tethered ballon, moored balloon: Federal Aviation Administration regards any balloon which is designed for carrying persons as an aircraft, and as such it must be certificated and operated in accordance with the applicable rules for aircraft. Such a passenger carrying balloon is considered tethered when it is inflated and held to the ground, in whatever manner. A moored balloon (for which there are no prescribed airworthiness standards because passenger carrying was not intended) is essentially any lighter-than-air object operated under 14 CFR [Code of Federal Regulation] Part 101. Such a balloon must be restrained with mooring lines to hold it stationary in the intended location, and the balloon must comply with the provisions of 14 CFR Part 101.

PHR

Gas, non-spherical, spherical captive balloon.

French

Domaine(s)
  • Types d'aéronefs
  • Stations, instruments et équipements météorologiques
DEF

Ballon [...] relié par un câble à un appareillage qui le monte ou le descend.

CONT

Les ballons captifs furent [au] XIXe siècle des attractions recherchées; par exemple le ballon géant de Giffard relié à un treuil à vapeur enlevait 50 voyageurs à la fois jusqu'à 500 m de haut.

CONT

En 1939, la France restait le seul belligérant à mettre en œuvre des compagnies de ballons. Elle dut très rapidement les retirer du front en raison des pertes qu'ils subirent [...] Les captifs furent désormais, dans toutes les aviations militaires, employés comme ballons de protection destinés à empêcher, grâce à un quadrillage de câbles d'acier, l'approche des avions ennemis à basse altitude.

OBS

Le ballon captif peut être équipé d'instruments pour faire des observations dans les basses couches de l'atmosphère. Il peut aussi servir à la surveillance aérienne, à l'observation des paysages (tourisme aérien), à l'étude du couvert végétal en forêt, à la photographie aérienne de basse altitude, au tournage de films, etc.

OBS

ballon captif : terme normalisé par l'ISO.

Record 2 2005-12-06

English

Subject field(s)
  • The Sun (Astronomy)
  • The Moon (Astronomy)
CONT

The variation of the direction in space is a conical motion, with vertex at the center of mass, around a perpendicular to the plane of the earth's orbit around the sun, in which the earth and the axis of rotation move together with no change in the position of the axis within the earth. This motion is caused by the gravitational attractions of the sun and the moon. The axis describes a sinuous conical surface at an irregularly varying rate; the motion is, therefore, represented as the resultant of a steady progressive motion in a circular cone of angular opening about 47°, called the "lunisolar precession"...

CONT

Equinoctial precession is a circular motion of Earth’s rotational axis with respect to the "fixed" stars, also known as lunisolar precession. It is caused by the torque of the Sun and Moon on the Earth’s rotational bulge.

French

Domaine(s)
  • Soleil (Astronomie)
  • Lune (Astronomie)
CONT

La précession, due à l'action du Soleil et de la Lune, s'appelle «précession luni-solaire».

OBS

lunisolaire : Cette graphie, puisée des Rectifications de l'orthographe recommandées par le Conseil supérieur de la langue française, est attestée dans le Petit Robert (2004).

English

Subject field(s)
  • Road Construction Equipment
  • Airport Runways and Areas
CONT

Dynamic methods. These methods involve a dynamic loading device which is mounted for travel on a vehicle or trailer and which is lowered, in position, onto the pavement. Devices make use of counter rotating masses, hydraulically actuated reciprocating masses, or falling weights(masses) to apply a series of pulses either in steady state by the reciprocating or rotating masses or attenuating by the falling mass.

French

Domaine(s)
  • Matériel de constr. (Voies de circulation)
  • Pistes et aires d'aéroport
CONT

Méthodes dynamiques. Ces méthodes font appel à un dispositif de charge dynamique qui est monté sur un véhicule ou une remorque pour en faciliter le transport et que l'on abaisse sur la chaussée à l'endroit choisi. Ces dispositifs comprennent soit des masses animées d'un mouvement rotatif en sens inverse l'une de l'autre, ou d'un mouvement alternatif obtenu à l'aide d'un mécanisme hydraulique, soit des poids (masses) que l'on laisse tomber pour appliquer une série d'impulsions. L'intensité de ces impulsions est constante dans le cas des masses animées d'un mouvement alternatif ou rotatif et décroissante lorsqu'il s'agit de masses qu'on laisse tomber.

Subject field(s)
  • Applications of Automation
DEF

Difference between actual position response and position desired or commanded of an automatic control system as determined in the steady state, that is, when all transient responses have died out.

French

Domaine(s)
  • Automatisation et applications
DEF

(...) l'aptitude du robot industriel à positionner et orienter le trièdre en conformité avec la position et l'orientation programmées. Cette exactitude peut être fonction de la position considérée et du mode d'accostage.

English

Subject field(s)
  • Computer Graphics
CONT

All joysticks perform in basically the same way; variations in features are what set one joystick apart from another. The most important feature to watch for is self-centering. Self-centering sticks are a poor choice for absolute cursor control because you must constantly hold the stick to keep a steady cursor position. Self-centering sticks can usually be converted to noncentering by simply removing the springs on the gimbals.
