Experimental investigation of the process of aviation kerosene dehydration in a fuel tank

The results of experimental investigations of the dehydration of aviation kerosene TS-1 in a model tank of volume 1.8 m³ are presented. The experiments were carried out under conditions simulating the regimes of a passengercarrying airplane fl ight at pressures 20–110 kPa and temperatures from –20 to +20^o C. The dehydration of kerosene was made by bubbling air enriched with nitrogen with a 10% volume fraction of oxygen at its specifi c consumption of 0.0002–0.0007 s^–1. A decrease in the concentration of the dissolved water to the values ensuring the absence of phase transitions in the water–kerosene system at temperatures down to –30^o C has been established. The concept of using on-board systems of generation of inert gases for dehydrating the kerosene in the fuel tank of an airplane under cruising fl ight conditions has been confi rmed.
