PITCH TUBE [7 records]

Record 1 2017-04-19

English

Subject field(s)
  • Nuclear Fission Reactors
CONT

Simplified reactor control resulting from reduced pressure tube lattice pitch and use of LEU fuel for a highly stable, more compact core. Further simplification achieved with mechanical zonal control rods and eliminating the liquid zone control system.

French

Domaine(s)
  • Réacteurs nucléaires de fission
CONT

Une simplification du contrôle-commande du réacteur résultant d'une diminution du pas de réseau des tubes de force et de l'utilisation du combustible LEU pour un cœur plus compact et extrêmement stable. La simplification a été poussée encore plus loin en recourant à des barres de réglage zonal mécanique et en éliminant le circuit à liquide de réglage zonal.

Subject field(s)
  • Technical Textiles
CONT

The Gold Plus retractable awning is characterized by a double supporting square steel bar enabling the easy installation of the available 17 ft. projection arms. The Gold Plus awning can be used to protect large spaces such as gardens, pool decks, patios or commercial areas... The arm and spring combination coupled with the oversized heavy wall roll tube is so strong the fabric will never sag and water runs off easily even with a shallow pitch.

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

Rapid vertical oscillations of the column of a mercury barometer.

CONT

The mercurial barometer... in its simplest form... consists of a glass tube a little more than 30 inches in length and of uniform internal diameter. With one end closed, the tube is filled with mercury, and inverted into a cup of mercury. The mercury in the tube falls until the column is just supported by the pressure of the atmosphere on the open cup, leaving a vacuum at the upper end of the tube. The height of the column indicates atmospheric pressure, greater pressures supporting higher columns of mercury. The mercurial barometer is subject to rapid variations in height, called pumping, due to pitch and roll of the vessel and temporary changes in atmospheric pressure in the vicinity of the barometer. Because of this... the mercurial barometer has been replaced at sea by the aneroid barometer.

Record 4 2001-05-17

English

Subject field(s)
  • Launchers (Astronautics)
CONT

The Ausroc 3(A3) launch vehicle has a liquid fuelled motor that burns JA-1 kerosene with liquid oxygen, and uses regenerative cooling. The motor produces 35 kN at sea level and has a burn time of 80 seconds. The motor is gimballed to facilitate pitch and yaw control. The wall of the combustion chamber, throat and expansion nozzle consists of 102 stainless steel tubes stacked side by side running parallel to the motor axis. The tubes will be brazed together and the assembly wrapped in a carbon fibre composite. The composite wrapping is used to relieve to tubes of the hoop stress generated by the combustion pressure(2 MPa), whilst the tubes contain the combustion heat(3500 K). The top end of the motor has a kerosene inlet manifolt, oxygen dome and injector block. The kerosene inlet manifold delivers kerosene to every second motor tube, where it travels down to the arse end of the motor. Here it enters the lower kerosene manifold which is a simple plenum ring. This allows the kerosene to flow into the other alternate tubes which deliver it back up to the inlet manifold. The inlet manifold then directs the kerosene to the injector block, which sprays it and the liquid oxygen into the combustion chamber.

English

Subject field(s)
  • Aeroindustry
CONT

The [helicopter] rotor shaft is a tube surrounding the mast and is wide enough to permit the pitch control linkage for the rotor blades to pass within it to a point above the rotor. From here, pitch-change motions are sent through tangential levers and push-rods down to the pitch-change horns.

OBS

CONT

L'arbre du rotor est un tube entourant un mât; il a un diamètre suffisant pour permettre aux biellette de commande de pas des pales de passer à l'intérieur jusqu'à un point situé au-dessus du rotor. A partir de celui-ci, des leviers tangentiels et des poussoirs transmettent aux cornes les commandes de changement de pas.
