FUELLING PRESSURE [7 records]

Record 1 2012-10-03

English

Subject field(s)
  • Aeronautical Engineering and Maintenance
CONT

Suction defuelling can be accomplished with a fuel truck defuelling pump through the pressure fuelling receptacle. Suction defuelling can also be accomplished by inserting a suction hose through the overwing fill ports, but this method is only recommended as a last resort. Aircraft system pumps and suction defuelling performed simultaneously through the pressure fuelling receptacle will provide the highest flow rates possible and should be used when time is critical.

CONT

Pressure fueling is used on many late model aircraft. This fueling process ... greatly reduces the time required to service large aircraft. There are also other advantages in the pressure fueling process. It eliminates aircraft skin damage and hazards to personnel and reduces the chances for fuel contamination. Pressure fueling also reduces the chance of static electricity igniting fuel vapors.

CONT

Pressure refuelling is much quicker than gravity fuelling. The fuel tanks are filled to the desired level according to the sequence selected by the fuelling personnel.

OBS

single point refuelling: term officially approved by the Aeronautical Terminology Standardization Committee (ATSC) - Helicopters.

  • Nuclear Power Stations
  • Nuclear Fission Reactors
OBS

The cylindrical tank containing the pressure tubes and moderator, called the "calandria", sits on its side. Thus, the CANDU core is horizontal. A fuelling machine visits each end of the core, one fuelling and the other de-fuelling, allowing operators to insert fresh fuel at alternate ends for neighbouring fuel channels.

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.
