When comparing the price of aviation gasoline from motor gasoline in virtually any foreign person a question “and where such a price is taken in principle on aircraft fuel?” The question itself is interesting enough, and the answer is not as straightforward as it might initially seem – so stop on it more .
The technical component
Specify aviation gasoline even different from “elite” automotive fuel: octane rating it above, composition and amount of fractions (unsaturated, saturated and aromatic hydrocarbons) also a little different, and for long-term storage requirements impose more stringent restrictions on its osmolyaemost and acidity. However, a fundamental difference lies in the presence in the aviation gasoline fuel additive, called TPP (tetraethyl lead). It is necessary not only to increase the octane rating of the fuel, but also simultaneously serves as a “grease” for certain parts of an aircraft engine (strictly speaking, not she, a metallic lead, released from her thin layer). fully “expel” TPP of aviation fuel could not be anyone in the world, reached the maximum – this grade with low content of TPP (eg, American Avgas 100LL and 100VLL).
Production and economic component
В России оптовая торговля бензином вынуждена балансировать между импортом и продукцией небольших частных предприятий, because large refinery production of leaded fuel do not wish to bind for several reasons:
- TPP throughout the former Soviet Union no longer produced, and this poisonous substance must somehow import, And on a larger scale;
- because TPP automobile and aviation gasoline, not only have separate workflows, but can not have a single container and reverse logistics (even in trace amounts TPP – this “resentment” catalytic converters for exhaust car);
- the total volume of the Russian market of aviation fuel consensually analysts estimate the figure of about thirty thousand tons per year, that the largest domestic refinery too little interest – kontrolkachestva since jet fuel is more difficult and costs.
In this way, meeting the demand for Russian aviation gasoline “small aircraft” It lies in small enterprises with their own, relatively low-tonnage (that is, a priori, with high cost / cost) production and import of two kinds (B-91/115 of Polish origin and 100LL) – hence obtained such “inhumane” price.
