Fueland Oil System

Theconstituents of a fuel and oil system comprise tanks, pumps amongothers as discussed in this paper. The tank position, shape andstructure are diverse according to the planned purpose of theaircraft. The purpose of the tank is to keep fuel or oil and, forthis reason they are made of materials that chemically unreactive tothe aviation oil(Luther, 2007).

Thereare two types of cells available. The first type is bladder-typecells constructed either by rubber or nylon which do not sealthemselves, used to minimize weight. The second type is integralcells usually located on the wing of the aircraft, and they arepermanent. They are dependent on the kind of the cavity to hold theweight of the fuel inside(&quotNRC, Boeing fuel cell system for safeuse of hydrogen on aircraft&quot, 2011).

Fueland oil lines are flexible metal tubing, usually coded with color atthe end for distinction, joining the fuel tank with other parts of anaircraft. Heat resistant hose is applicable where the lines areexposed to intense warmth. Mostly they are located in the tank toensure any leakage do not cause any fire hazard (Luther, 2007).

Strainersare fitted in the tank openings and often in the tank pitch collarsto prevent particles from getting into the system. Also, due to theirlocation, they trap traces of water that might be accessing thesystem(&quotNRC, Boeing fuel cell system for safe use of hydrogen onaircraft&quot, 2011).

Auxiliarypumps distribute fuel and oil under pressure to the entry of theengine compelled pump. The pumps are relevant to the systemespecially at high altitudes, as they allow the required pressurenecessary for oil or fuel to boil. Auxiliary pumps being boosterpumps also assist in the transmission of oil from one tank to theother(Luther, 2007).

Propermanagement procedures for fuel and oil systems include the avoidanceof direct contact with oil and fuel, especially when hot, with othermatters reducing the chances of mixing with them which may result inan explosion from the thermal shock. The safe keeping and labellingof containers containing various petroleum products reduce improperuse of the product which may affect the performance of the system.Also, it is recommended when filling the oil and fuel tanks it shouldbe done to a level several inches below the cork. The oil system isdependent and requires minimal preservation, altering oil and filtersregularly and visual check (Luther, 2007).
