TURN HEIGHT [17 records]

Record 1 2022-11-30

English

Subject field(s)
  • Atmospheric Physics
CONT

The earth's atmosphere is mostly transparent to the incoming solar radiation, and hence the above radiation from the sun is absorbed by the earth surface. The earth's atmosphere in turn absorbs the terrestrial long wave radiation from the earth surface resulting in a situation where the atmosphere is primarily heated from below. This results in a vertical distribution of air temperature, wherein the air temperature decreases with height.

CONT

SPIRAL DIVE. When you turn a series of tightening 360s the paraglider will enter a spiral-a highly banked turn with rapid height loss. The longer you hold the inside brake on, the faster the turn becomes. Safe descent rates of 8 metres/second(500 ft/min approx.) are possible in a spiral dive, but at these high speeds and G-forces it is easy to become disorientated, so you must pay particular attention to altitude.

CONT

It is possible to achieve sink rates as high as 5 or 6 metres/second by linking 360° turns [i.e. in a spiral dive - although the French says linking turns].

OBS

360° turns: term used in the plural.

CONT

On parle de 360 engagés quand le pilote, à haute altitude, engage un virage à 360° et le poursuit jusqu'à faire 3 ou 4 tours, ce qui l'amène à réaliser une spirale. C'est une technique qui nécessite tout de même une maîtrise du vol. La force centrifuge augmente à chaque tour et n'est pas à négliger, ni le taux de chute qui peut dépasser les 10 m/s.

CONT

Au cours de 360° enchaînés, des taux de chute de l'ordre de 5 à 6 m/s sont atteints.

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

Barometer whose sensitive element is composed of one or a series of aneroid capsules.

CONT

Pressure is measured using a barometer. An aneroid barometer has a capsule [usually metallic] which collapses slightly when pressure increases and expands when it decreases. These motions are transferred to a dial and calibrated in either millimetres of mercury or millibars or inches.

CONT

The aneroid barometer was invented by a Frenchman, Lucien Vidie, in 1843. He produced a metallic barometer which he called an aneroid, from the Greek, meaning "without liquid. "The principle of the aneroid barometer is the change in height of a sealed metallic chamber which has flexible upper and lower surfaces. As the pressure changes, so the height of the chamber varies which, in turn, moves an index pointer.

CONT

Aneroid barometer is temperature compensated at a given pressure level by adjustment of the residual gas in the aneroid or by a bimetallic link arrangement. The instrument is subject to uncertainties due to variations in the elastic properties of the spring and capsules, and due to wear in the mechanical linkages.

OBS

aneroid barometer: term officially approved by the International Civil Aviation Organization (ICAO).

DEF

[...] baromètre [dont] l'organe sensible [est] constitué par une ou plusieurs capsules anéroïdes dont la déformation élastique est fonction de la pression atmosphérique.

CONT

Le baromètre anéroïde est formé d'une capsule déformable vide d'air qui s'aplatit plus ou moins sous l'action de la pression atmosphérique. La déformation de la capsule est amplifiée par un système de leviers et transmise soit à une aiguille indicatrice, soit à un stylet enregistreur.

OBS

capsule anéroïde : Capsule métallique à parois minces, où l'on fait un vide partiel déterminé, munie d'un dispositif évitant l'écrasement par la pression atmosphérique et qui se déforme sous l'action de cette pression. (La mesure de cette déformation, par différentes techniques, permet d'obtenir la valeur de la pression.)

OBS

Le plus souvent, le baromètre anéroïde est à capsule métallique mais il peut également être à tube.

It effectively gives each pin twice the keying versatility, since the key cut can be the right depth and twist, but if it's not under the chisel tip, you lose.

The comb nephoscope consists essentially of a series of rods assembled in the form of a comb, and mounted on a vertical rod with the "teeth" of the comb horizontal. The vertical rod is free to turn, and is rotated by means of a pulley and rope device. The observer selects a recognizable feature of the cloud base, and then rotates the comb of the nephoscope until that feature appears to move along the longitudinal member of the comb.... By using the "teeth" of the comb, and a timepiece, the observer may time the motion of the cloud. The speed of the cloud may then be determined, provided its height is known.

The American Space Agency Nasa... is putting several million dollars into the project under its advanced concepts programme. At the heart of a space elevator would be a cable reaching up as far as 100, 000km from the surface of the Earth. The earthbound end would be tethered to a base station, probably somewhere in the middle of the Pacific ocean. The other end would be attached to an orbiting object in space acting as a counterweight, the momentum of which would keep the cable taut and allow vehicles to climb up and down it. A space elevator would make rockets redundant by granting cheaper access to space. At about a third of the way along the cable-36, 000 km from Earth-objects take a day to complete a full orbit. If the cable's centre of gravity remained at this height, the cable would remain vertical, as satellites placed at this height are geostationary, effectively hovering over the same spot on the ground. To build a space elevator such a geostationary satellite would be placed into orbit carrying the coiled-up cable. One weighted end of the cable would then be dropped back towards Earth, while the other would be unreeled off into space. Mechanical lifters could then climb up the cable from the ground, ferrying up satellites, space probes and eventually tourists. The biggest technical obstacle is finding a material strong but light enough to make the cable; this is where the carbon nanotubes come in. These are microscopically thin tubes of carbon that are as strong as diamonds but flexible enough to turn into fibre. In theory, a nanotube ribbon about one metre wide and as thin as paper could support a space elevator.

La NIAC (Institut des Concepts Avancées de la NASA) a publié une étude fin 2002 sur tous les aspects d'un système d'ascenseur spatial, de la construction aux opérations. Premièrement, l'ascenseur serait constitué d'un câble d'une longueur de 91 000 km et d'un diamètre variant de 1 micron à 11.5 cm. Ce filin serait mis en orbite à l'aide d'une navette spatiale aidée de quelques propulseurs supplémentaires, qui, une fois en orbite géostationnaire, serviraient de contrepoids. Les forces centripètes repousseraient alors la partie haute du filin vers l'espace tandis que la partie basse serait attirée par la Terre, mettant le tout en tension. Ce premier lien serait capable d'envoyer plus d'une tonne en orbite. Il suffira ensuite d'utiliser ce premier câble pour en mettre en orbite de nouveaux. Ces filins seront constitués de nanotubes de carbone. Le plus gros défi technologique serait de construire 91 000 km de nanotubes car aujourd'hui la technologie ne permet d'en construire que quelques centimètres. Le ratio actuel nanotube/résine epoxy est de 60/40. Il faudra réussir à descendre à 98/2. Les principaux risques liés au transport par ascenseur seront dus aux météorites, aux ouragans ou aux attaques terroristes. Le filin pourra être réparé in-situ. Ce système ne nécessiterait pas de maîtriser la fusion nucléaire. De simples batteries et panneaux solaires suffiront à alimenter l'ascenseur. La plupart des technologies nécessaires existent déjà ou existeront dans le court terme. Les prévisions actuelles prévoient un budget de 7 à 10 milliards sur 15 ans.

The buckwheat flower has no petals-the sexual parts, the ovary, three styles and eight stamens being enclosed in the petallike sepas. Four of the anthers bend out but turn their pollen inward. The other four turn their pollen outward(Knuth 1909, pp. 341-342). Some plants have flowers, referred to as the "thrum" type, with short styles and long filaments so the stamens extend above the styles. Other flowers, referred to as "pin" types, have long styles and short filaments so the stigma is avobe the anthers. Occasionally, the styles and stamens are at the same height. The long stamens and filaments are fully 3 mm; the shorter ones, about 2 mm. Although each plant bears flowers of only one form, the seeds from either form will produce plants having the dimorphic forms in about equal numbers. The thress styles lead to a single ovary with one ovule, so a flower can produce only one seed, which is about one-quarter inch long.
