34、aft is an importantperformance requirement. The thermal stability measurements are related to the amount of deposits formed in the engine fuelsystem on heating the fuel in a jet aircraft. Commercial jet fuels should be thermally stable at fuel temperature as high as 163 C(325 F). Such fuels have bee
35、n demonstrated to have inherent storage stability.X1.3.2 In 1973, Test Method D3241 replaced Method of Test D1660, known as the ASTM Coker for the determination ofoxidative thermal stability. (See CRC Report 450, dated 1969 and revised in 1972. See also Bert and Painters SAE paper730385.15) Today, a
36、 single pass/fail run with the tube temperature controlled at 260 C is used to ensure compliance with thespecifications minimum requirements. For a more complete characterization of a fuels thermal stability, a breakpoint can beobtained. The breakpoint is the highest tube temperature at which the fu
37、el still passes the specification requirements of the tubedeposit color and pressure differential. Normally, obtaining a breakpoint requires two or more runs at differing tube temperatures.Breakpoints are therefore not used for quality control, but they serve mostly for research purposes.X1.4 Combus
38、tionX1.4.1 Jet fuels are continuously burned in a combustion chamber by injection of liquid fuel into the rapidly flowing stream ofhot air. The fuel is vaporized and burned at near stoichiometric conditions in a primary zone. The hot gases so produced arecontinuously diluted with excess air to lower
39、 their temperature to a safe operating level for the turbine. Fuel combustioncharacteristics relating to soot formation are emphasized by current specification test methods. Other fuel combustioncharacteristics not covered in current specifications are burning efficiency and flame-out.X1.4.2 In gene
40、ral, paraffin hydrocarbons offer the most desirable combustion cleanliness characteristics for jet fuels. Naphthenesare the next most desirable hydrocarbons for this use.Although olefins generally have good combustion characteristics, their poorgum stability usually limits their use in aircraft turb
41、ine fuels to about 1 % or less. Aromatics generally have the least desirablecombustion characteristics for aircraft turbine fuel. In aircraft turbines, they tend to burn with a smoky flame and release a greaterproportion of their chemical energy as undesirable thermal radiation than the other hydroc
42、arbons. Naphthalenes or bicyclicaromatics produce more soot, smoke, and thermal radiation than monocyclic aromatics and are, therefore, the least desirablehydrocarbon class for aircraft jet fuel use. All of the following measurements are influenced by the hydrocarbon composition ofthe fuel and, ther
43、efore, pertain to combustion quality: luminometer number, smoke point, percent naphthalenes, and percentaromatics.16X1.4.2.1 Smoke PointThis method provides an indication of the relative smoke-producing properties of jet fuels and is relatedto the hydrocarbon-type composition of such fuels. Generall
44、y, the more highly aromatic the jet fuel, the more smoky the flame.A high smoke point indicates a fuel of low smoke-producing tendency.X1.4.2.2 AromaticsThe combustion of highly aromatic jet fuels generally results in smoke and carbon or soot deposition, andit is therefore desirable to limit the tot
45、al aromatic content as well as the naphthalenes in jet fuels.X1.4.2.3 Percent NaphthalenesThis method covers measurement of the total concentration of naphthalene, acenaphthene, andalkylated derivatives of these hydrocarbons in jet fuels containing no more than 5 % of such compounds and having boili
46、ng pointsbelow 600 F (316 C).X1.5 Fuel Metering and Aircraft RangeX1.5.1 DensityDensity is a property of a fluid and is of significance in metering flow and in mass-volume relationships for mostcommercial transactions. It is particularly useful in empirical assessments of heating value when used wit
47、h other parameters, suchas aniline point or distillation. A low density may indicate low heating value per unit volume.15 Bert, J.

49、f CombustionThe design of aircraft and engines is based on the convertibility of heat into mechanical energy.The net heat of combustion provides a knowledge of the amount of energy obtainable from a given fuel for the performance ofuseful work; in this instance, power. Aircraft design and operation are dependent upon the availability of a certain predeterminedminimum amount of energy as heat. Consequently, a reduction in heat energy below this minimum is accompanied by an increasein fuel consumption with corresponding loss of range. Therefore, a minimum net hea
