目前已研究出了若干种供巡航导弹使用的高能量密度的液体燃油(可以通过添加固体燃料微粒的方法获得)。这些特殊的燃油的使用给导弹系统和主发动机带来了一些必须克服的特殊的流变学问题和化学方面的问题。高能量密度燃油包括的范围是,从纯液体(如,RJ-4、 RJ-5和JP-10)燃油到胶状和悬浊状的燃油。使用这些燃油时碰到的最严重的问题之一是,在发动机起动时燃油雾化和点火或重新点火都比较困难。已把甩油盘式燃油喷射器作为一种适于使用这些燃油的一种手段进行了验证。在使用甩油盘式燃油喷射器方面,特里达因CAE公司研制和生产的发动机已积累了175小时的使用各种高密度和悬浊燃油的试验经验。在试验中,不仅验证了巡航导弹主发动机可以使用高能量密度燃油,而且还验证了甩油盘式燃油喷射器在使用“脏的”燃油(比如,含有碳微粒的Bunker C燃油和热解得来的燃油)时工作的情况。在用高能量密度燃油作的试验中还鉴定了一些与发动机有关的问题,比如燃烧室耐久性和燃油系统的抽油与调节。下一步的研究计划将对这些问题作定量分析并鉴定一些解决这些问题的方法。
A number of high-energy-density liquid fuels (available through the addition of solid fuel particles) have been developed for cruise missiles. The use of these special fuels has given the missile system and main engine special rheological and chemical problems that must be overcome. High energy density fuels range from fueling pure liquids (eg, RJ-4, RJ-5 and JP-10) to gelatinous and suspension fuels. One of the most serious problems encountered when using these fuels is that it is more difficult to atomize and ignite or re-ignite the fuel at engine start-up. Oil-throw disc fuel injectors have been validated as a suitable means of using these fuels. In the area of throw-off disc fuel injectors, Trine Motors, which has been developed and manufactured by CAE, has accumulated 175 hours of test experience using a variety of high-density and suspended fuels. In the test, not only was it verified that the cruise missile main engine could use high energy density fuel, but also the use of “discarded” fuel (such as Bunker C fuel containing carbon particles and pyrolysis Fuel coming) when working. Some tests related to the engine were also identified in tests using high energy density fuels, such as combustion chamber durability and pumping and conditioning of the fuel system. The next research project will quantify these problems and identify some ways to solve them.
