Record 1 2021-07-14

English

Subject field(s)
  • Launchers (Astronautics)
DEF

An auxiliary rocket which fires in the direction in which the vehicle is pointed, used, for example, in separating two stages of a vehicle.

OBS

In direction of travel, hence rocket increases speed of satellite in order to reach higher orbit.

French

Domaine(s)
  • Lanceurs (Astronautique)
DEF

Fusée de séparation de deux étages d’un lanceur, fixée sur l'étage supérieur, dont la poussée est orientée dans le sens du mouvement de ce lanceur.

Record 2 2020-10-30

English

Subject field(s)
  • Spacecraft
DEF

A launch vehicle that uses two or more rocket stages, each of which contains its own engines and propellant.

CONT

Even if [the company] could get the technology working, so the X-33 was fully reusable, its ability to carry a payload would have been dramatically lower than a traditional multi-staged rocket.

Key term(s)
  • multistage rocket
  • multistaged rocket
  • multistep rocket

French

Domaine(s)
  • Engins spatiaux
CONT

L’effet Oberth est aussi à la base du comportement des fusées à étages multiples, dont le dernier étage peut produire bien davantage d’énergie cinétique que la somme de l’énergie potentielle chimique des propergols qu’elle emporte.

Record 3 2009-01-14

English

Subject field(s)
  • Spacecraft
CONT

The principle of staging rockets is similar to a plane jettisoning its empty wing tanks. When half the fuel is burned the rest is pumped into center tanks and empty rockets dropped.

French

Domaine(s)
  • Engins spatiaux
CONT

Sur le principe de la fusée à étages multiples [...] l'engin abandonne des charges inutiles à mesure que le combustible est consommé [...] on largue les réservoirs correspondants.

Record 6 2005-02-03

English

Subject field(s)
  • Launchers (Astronautics)
CONT

When it is completed, the K-1 will be the first commercially available, fully reusable launch vehicle to provide low-cost access to space for low earth-orbiting satellites. The K-1 is powered by modified Russian rocket engines, provided by Aerojet, that burn LOX (liquid oxygen) and kerosene. Thrust is produced when the appropriate mixture of LOX and kerosene is pumped into the combustion chamber and ignited.

CONT

The K-1 will be able to deliver approximately 3,200 kg (7,000 lbm) of pressurized cargo to the ISS and return approximately 900 kg (2,000 lbm) of recoverable downmass. The K-1 cargo module can accommodate a volume of 30 m³ (1,000 ft³) equivalent to five International Standard Payload Racks. The K-1 is also capable of providing up to 40km (25 nmi) reboost and attitude control for ISS, an important feature for maintaining the ISS orbit, and conducting on-orbit technology demonstration as precursor risk reduction missions.

PHR

K-1 is equipped with an active dispenser.

PHR

K1 fully reusable, two-stage.

French

Domaine(s)
  • Lanceurs (Astronautique)
CONT

Le premier vaisseau spatial entièrement réutilisable sera l'engin K-1 de la Société Kistler Aerospace. Il devrait voler à la fin de 1999. Cette fusée à deux étages utilise des moteurs russes qui fonctionnent au kérosène et à l'oxygène liquide. Les étages séparés retourneront sur Terre par parachute.

French

Domaine(s)
  • Lanceurs (Astronautique)
CONT

Mais une première série de modifications interviendra dès 1997. Tout d’abord, la fusée n’ aura plus d’éléments provenant des autres pays de la CEI et sera donc de construction purement nationale. Ensuite, le système de pilotage analogique sera remplacé par un nouveau calculateur de bord qui permettra d’éliminer le pointage azimutal, de diminuer le poids de 200 kg et de réduire de 40 % l'aire de retombées des étages.

OBS

Lanceur Ariane.

Record 8 2002-06-10

English

Subject field(s)
  • General Scientific and Technical Vocabulary
CONT

In order to study the ozone layer, it is important to get instruments into this level of atmosphere. One method of doing this is to place the instruments in a rocket that lifts the instruments to the top of the ozone layer (48,000 m) and lets them parachute back down to earth. ... There are two important stages to consider in the rocket's ascent. The rocket will speed up while its engine is firing, and then slow down after the engine has shut off.

CONT

The future scientists and engineers will seek to measure radiation levels, audio frequencies, and light waves during the rocket ascent and descent.

French

Domaine(s)
  • Vocabulaire technique et scientifique général
CONT

S. Petat a étudié plusieurs intégrateurs numériques d’équations algébrico-différentielles, et a plus spécialement travaillé sur l’intégration numérique de l’arc singulier dans le problème de Goddard (ascension optimale d’une fusée).
