Another characteristic dress is molecular-structural detail. A. W. Weitkamp, in his study of the hydrogenation of polycyclic aromatic molecules, provides us with an excellent demonstration of the role of the finer points of stereochemical architecture and conformational adaptability. Incidentally, his introductory sentence ( Perhydro derivatives of monomethyl- and dimethylnaphthalenes should be among the very best candidates for components of.. . fuels for aviation turbine engines ) provides an interesting illustration for the strong motivating role of the industrial community in the expansion of catalytic research.

Jet fuel is classified as aviation turbine fuel, and in the specifications, ratings relative to octane number are replaced with properties concerned with the ability of the fuel to bum cleanly. Jet fuel is a light petroleum distillate that is available in several forms suitable for use in various types of jet engines. The exact composition of jet fuel is established by the U.S. Air Force using specifications that yield maximum performance from the aircraft. The major jet fuels used by the military are JP-4, JP-5, JP-6, JP-7, and JP-8. 

The first aviation gas turbine engines were regarded as having noncriti-cal fuel requirements. Ordinary illuminating kerosene was the original development fuel, but the increased complexity in design of the engine has required fuel specification tests to be more complicated and numerous. 

The low-density products manufactured in the SMDS process are predominantly paraffinic and free from impurities such as nitrogen and sulphur. Both the kerosine and gas oil have excellent combustion properties (smoke point and cetane number), and their cold-flow characteristics meet all relevant specifications - even the stringent freezing point requirements of aviation turbine kerosine. They also make excellent blending components for upgrading low-quality stock that would otherwise have to be used in fuel oil. The excellent quality of the products was proved in extensive engine tests. 

RCT are designed to successfully solve a whole number of tasks in nuclear power when testing fuel elements, in aviation and space industry when testing construction materials, nozzles and engine units, turbine blades and parts, in electromechanical industry-cables switching elements, electric motors in defense sphere- charges, equipment in prospecting for research of rock distribution and detection of precious stones in samples.

In this paper, an overview of the important phenomena is given. The supercritical combustion process employed is also known to occur in liquid propellant rocket motors (e.g. in LOX/GH2-motors), liquid propellant guns (LPG), advanced aviation gas turbines and, to a lesser extent, in internal combustion engines. Supercritical combustion is characterized by (1) injection of at least one liquid state fuel component into a chamber which is thermodynamically in the supercritical state, (2) density ratios of fuel to oxidizer near one, (3) supercritical phase transitions of fluid-particles due to combustion, (4) non-ideal properties of the fluids. Additionally a short description of pertinent design criteria is given.
