Limiting values for
24、 the two types of fuel covered areplaced on fuel properties believed to be related to the perfor-mance of the aircraft and engines in which they are mostcommonly used.X1.2.2 The safe and economical operation of aircraft re-quires fuel that is essentially clean and dry and free of anycontamination pr
25、ior to use. It is possible to measure a numberof jet fuel characteristics related to quality.X1.2.3 The significance of standard tests for fuel propertiesmay be summarized for convenience in terms of the technicalrelationships with performance characteristics as shown inTable X1.1.X1.2.4 The accepta
26、bility of additives for use must ulti-mately be determined by the engine and aircraft type certificateholder and must be approved by his certifying authority. In theUnited States ofAmerica, the certifying authority is the FederalAviation Administration.X1.3 Thermal StabilityX1.3.1 Stability to oxida
27、tion and polymerization at theoperating temperatures encountered in certain jet aircraft is animportant performance requirement. The thermal stability mea-surements are related to the amount of deposits formed in theengine fuel system on heating the fuel in a jet aircraft.Commercial jet fuels should
28、 be thermally stable at fueltemperature as high as 163 C (325 F). Such fuels have beendemonstrated to have inherent storage stability.X1.3.2 In 1973, Test Method D3241 replaced Method ofTest D1660, known as the ASTM Coker for the determinationof oxidative thermal stability. (See CRC Report 450, date

For a morecomplete characterization of a
32、fuels thermal stability, a break-point can be obtained. The breakpoint is the highest tubetemperature at which the fuel still passes the specificationrequirements of the tube deposit color and pressure differential.Normally, obtaining a breakpoint requires two or more runs atdiffering tube temperatu
33、res. Breakpoints are therefore not usedfor quality control, but they serve mostly for research purposes.X1.4 CombustionX1.4.1 Jet fuels are continuously burned in a combustionchamber by injection of liquid fuel into the rapidly flowingstream of hot air. The fuel is vaporized and burned at nearstoich
34、iometric conditions in a primary zone. The hot gases soproduced are continuously diluted with excess air to lower theirtemperature to a safe operating level for the turbine. Fuelcombustion characteristics relating to soot formation are em-phasized by current specification test methods. Other fuelcom
35、bustion characteristics not covered in current specificationsare burning efficiency and flame-out.X1.4.2 In general, paraffin hydrocarbons offer the mostdesirable combustion cleanliness characteristics for jet fuels.Naphthenes are the next most desirable hydrocarbons for thisuse. Although olefins ge
36、nerally have good combustioncharacteristics, their poor gum stability usually limits their usein aircraft turbine fuels to about 1 % or less. Aromaticsgenerally have the least desirable combustion characteristicsfor aircraft turbine fuel. In aircraft turbines, they tend to burnwith a smoky flame and
37、 release a greater proportion of theirchemical energy as undesirable thermal radiation than the otherhydrocarbons. Naphthalenes or bicyclic aromatics producemore soot, smoke, and thermal radiation than monocyclicaromatics and are, therefore, the least desirable hydrocarbonclass for aircraft jet fuel
38、 use. All of the following measure-ments are influenced by the hydrocarbon composition of thefuel and, therefore, pertain to combustion quality: luminometernumber, smoke point, percent naphthalenes, and percent aro-matics.16X1.4.2.1 Smoke PointThis method provides an indicationof the relative smoke-
39、producing properties of jet fuels and isrelated to the hydrocarbon-type composition of such fuels.Generally, the more highly aromatic the jet fuel, the moresmoky the flame. A high smoke point indicates a fuel of lowsmoke-producing tendency.X1.4.2.2 AromaticsThe combustion of highly aromatic jetfuels
40、 generally results in smoke and carbon or soot deposition,and it is therefore desirable to limit the total aromatic contentas well as the naphthalenes in jet fuels.X1.4.2.3 Percent NaphthalenesThis method covers mea-surement of the total concentration of naphthalene,acenaphthene, and alkylated deriv
41、atives of these hydrocarbonsin jet fuels containing no more than 5 % of such compoundsand having boiling points below 600 F (316 C).X1.5 Fuel Metering and Aircraft RangeX1.5.1 DensityDensity is a property of a fluid and is ofsignificance in metering flow and in mass-volume relationshipsfor most comm
42、ercial transactions. It is particularly useful inempirical assessments of heating value when used with otherparameters, such as aniline point or distillation. A low densitymay indicate low heating value per unit volume.X1.5.2 Net Heat of CombustionThe design of aircraft andengines is based on the co
43、nvertibility of heat into mechanicalenergy.

Aircraftdesign and operation are dependent upon the availability of acertain predetermined minimum amount of energy as heat.Consequently, a reduction in heat energy below this minimumis accompanied by an increase in fuel consumption withcorresponding loss of range. Therefore, a minimum net heat
49、ofcombustion requirement is incorporated in this specification.The determination of net heat of combustion is time consumingand difficult to conduct accurately. This led to the developmentand use of the aniline point and density relationship to estimatethe heat of combustion of the fuel. This relationship is usedalong with the sulfur content of the fuel to obtain the net heatof combustion by Test Method D4529 for the purposes of thisspecification. An alternative calculation, Test Method D3338,is based on correlations of aromatics content, gravity, volatility,and sulf
