' ...aviation fuel is a small factor in a field of large and powerful forces. Its future is at the mercy of various developments: political, sociological, economic and technical.

Heat-transfer parameters for an annular packed bed

“…Greek Symbols al, aZ, ,8 = constants in eq 5 and 6 p, = gas viscosity, kg/(m.s) Subscripts g = gas o = initial condition or outer wall p = particle r = radial direction w = inner wall z = axial direction Vere, 1969;Petrarca, 1974;Goodger and Vere, 1985;Grabel, 1977).…”

“…More recent fuel lubricity problems have been experienced by military aircraft (Biddle et al, 1987;Grabel, 1977). These recent fuel lubricity related problems are believed to be a result of lubricity additive loss from fuel.…”

“…This additive was previously used to decrease iubricity fuels have occurred in the past 20 years. Aircraft corrosion to fuel-handling and -storage systems (Goodger components which derive lubrication from fuel have been and Vere, 1985). The additive is effective as a corrosion' experiencing increased wear and mechanical failure.…”

“…In early This additive's current important use is to increase the 1966, the Air Force designated corrosion inhibitor as a lubricity of low-lubricity jet fuel (Moses et al, 1984;. These recent fuel lubricity related Goodger and Vere, 1985). Lubricity is recognized as one problems are believed to be a result of lubricity additive of the most critical properties degraded by refining proloss from fuel.…”

Aviation Fuel Development - Past Highlights and Future Prospects

“…A fuel's tendency to knock was characterized by its "octane rating", developed by Thomas Edgar, which compared a given gasoline's tendency to knock to a reference fuel composed of a mixture of n-heptane (octane #=0) and iso-octane (octane #=100). On this scale, the Wright brother's 1903 fuel has been estimated to be 38 octane 3,4 , with their 1910 fuel estimated as 58 octane 5 . By 1932, industry had generally adopted a standardized method for knock rating, using an engine designed by H. L. Horning of the Waukesha Motor Company for the CFR Committee, and Edgar's fuel standards.…”
