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 m 3 are presented. The experiments were carried out under conditions simulating the regimes of a passengercarrying airplane flight at pressures 20–110 kPa and temperatures from –20 to +20°C. The dehydration of kerosene was made by bubbling air enriched with nitrogen with a 10% volume fraction of oxygen at its specific 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°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 flight conditions has been confirmed.
