FUEL OPENING PRESSURE [3 records]

Record 1 2008-05-05

English

Subject field(s)
  • Aircraft Systems
CONT

Normal fuelling is accomplished through dual fuel nozzle adapters located on the right wing leading edge spar at the fuelling stations. All fuelling operations, except fuel pump control, are accomplished at the fuelling station. Opening the station access door applies DC power to the fuelling system and removes the N3 inhibit to the centre tank fuel pumps. Fuel flows through the dual nozzles to pressurise a fuelling manifold. Fuelling valves control the flow of fuel from the fuelling manifold into each of the three switches on the fuelling panel. A fuel quantity may be preselected for each tank. The fuelling valves close automatically when the preselected quantity is reached or when the tank is full, whichever occurs first. A tank overfill system is provided to prevent fuel spillage. If any fuel is sensed in the surge tanks during fuelling, a signal is sent to close all fuelling valves. The aircraft is filled automatically by hydrant or tank truck pressure. All tanks may be fuelled at the same time. The main tanks may also be fuelled manually through over wing fill ports. There are no over wing fill ports for the centre tank.

CONT

Chaque raccord de remplissage de réservoir de carburant doit empêcher la pénétration de carburant dans toute partie de l'avion autre que le réservoir lui-même. De plus, [chaque] raccord de remplissage encastré qui peut recueillir une quantité appréciable de carburant doit avoir un drain qui assure un écoulement sans mouiller l'avion, [chaque] bouchon de prise de remplissage doit comporter un joint étanche au carburant, et [chaque] point de remplissage carburant, à l'exception des points de raccord de remplissage de carburant sous pression, doit être aménagé pour relier électriquement l'avion à l'équipement de remplissage de carburant au sol.

point de remplissage : terme uniformisé par les Comités d'uniformisation de la terminologie aéronautique (CUTA) - Opérations aériennes et Maintenance.

Subject field(s)
  • Burners and Steamfitting
CONT

Domestic burners... employ either one of two methods to prepare the fuel oil for combustion. These are atomization(spraying) and vaporization(heating). Atomization or spraying is divided into three types, namely, high-pressure atomization, low-pressure atomization, and centrifugal atomization... Low-pressure air atomization is also a well-known method that has been used successfully by domestic oil burners to prepare the oil for combustion. This method is peculiar to low-pressure burners. These burners achieve their objective by delivering oil and air to the nozzle at a pressure of from 1 to 15 psi, depending upon the make of the burner. With these burners the oil and air come in contact with each other before leaving the burner. The air is used to atomize the oil into fine particles, and it leaves the nozzle opening in the form of a mist.

CONT

Pulvérisation par l'air sous basse pression. Les brûleurs qui fonctionnent en utilisant de l'air sous basse pression sont construits pour des débits compris entre 5 et 150 kg/h lorsqu'il s'agit de pulvérisateurs statiques et entre 5 et 1 500 kg/h pour les pulvérisateurs rotatifs (coupelle rotative).

Subject field(s)
  • Aeroindustry
CONT

The TRI60 demonstrated start-up and acceleration to cruise thrust in less than five seconds entirely by means of the windmilling effect created by ram pressure. At launch, the only engine-starting actions required are the opening of the fuel cock and the firing of two pyrotechnic igniters in the combustion chamber.

CONT

Saab-Scania (...) participait à ces essais (...) qui ont démontré l'aptitude du turboréacteur à atteindre le régime de croisière en moins de 5 secondes sous le seul effet de l'autorotation créée par la pression dynamique, les actions requises au moment du lancement se limitant à l'ouverture de la vanne de carburant et au déclenchement des deux allumeurs pyrotechniques de la chambre de combustion.
