The characteristics

development trend and existing problems of liquefied natural gas(LNG)as aviation fuel were analyzed. The differences among LNG

new and traditional aviation fuels were compared and analyzed by using the method of horizontal comparison in order to study the feasibility of LNG as the aviation fuel. The results showed that LNG had the advantages of wide source

good economy and strong adaptability compared with the new aviation substitute fuels. Compared with the traditional aviation fuel

LNG had large reserves which can be used for more than 100 years; it also had the advantages of wide flammability limit

low emissions of NOx only accounting for 1/4 of aviation kerosene; LNG had high energy density and lower cost

as the fuel cost is only half of the aviation gasoline and 1/3 of aviation kerosene. As a highly potential aviation fuel

LNG also can be used for cooling high temperature components of engine with cold energy. It was also pointed out that many work had to be done on matching power system with the aircraft structure

effectively transforming the fuel phase and researching the reaction characteristics of different fuels in the combustion chamber if LNG was used as an aviation fuel.
