在航空替代燃料缺乏足够飞行数据,几乎不可能通过有限发动机和飞行实验来评价其安全特性状况下,研究开发了一种简便却可保证适航安全性的方法来研究航空替代燃料的安全性能.“即用性”航空替代燃料被认为是发动机更换最频繁的部件,从而采用相似类比、使用经验方法来验证“即用性”燃料的适航符合性.以航空煤油实际使用经验为基准,提炼燃料性能、燃料系统、燃烧性能、发动机性能、飞机性能5个层次上参数化描述的安全边界,与通过航空替代燃料在5个层次上得到的工作边界进行相似类比,从而预测发动机使用替代燃料的安全性.该方法提炼了替代燃料在发动机安全性上的判定准则,还降低了认证流程的燃料成本和时间成本.
In the absence of sufficient flight data for alternative aviation fuel, it is almost impossible to assess its safety features through limited engine and flight experiments. A simple but safe method of ensuring airworthiness was studied to study the safety of alternative aviation fuel. “Usability” Aviation alternative fuels are considered to be the most frequent part of engine replacement, using a similar analogy and using empirical methods to verify airworthiness compliance for “ready-to-use” fuels. Based on practical experience with aviation kerosene As the benchmark, refine the safety boundaries parameterized on the five levels of fuel performance, fuel system, combustion performance, engine performance, and aircraft performance, and analogize with the working boundary obtained by aviation alternative fuel at five levels to predict the engine The safety of alternative fuels This methodology refined the criteria for determining the safety of alternative fuels and also reduced the fuel and time costs of the certification process.
