前言在航空环境中,喷气燃料可能遇到各种温度和压力,在周围环境或内部热源加热时,这种温度和压力就有可能使其形成可燃的蒸汽—空气混合物而被点燃。其他航空可燃液体如发动机油、润滑油和液压油,虽然它们着火时所需要的温度比喷气燃料要高,但也可能形成可燃的蒸汽—空气混合物。为估计它们在各种实际环境中着火的可能性,必须具备这些可燃物在遇到各种热源时其着火性能的有关知识。尽管对许多航空可燃液体的有关这方面的知识已有很多的报导,但所得到的数据都分散在大量的刊物之中。因此,应空军的要求编写了本 INTRODUCTION In aeronautical environments, jet fuel may encounter a wide range of temperatures and pressures that can be ignited by the formation of a flammable vapor-air mixture as the ambient or internal heat source heats up. Other aviation flammable liquids such as engine oils, lubricants and hydraulic fluids, although they require a higher temperature when ignited than jet fuel, may also form a flammable vapor-air mixture. In order to assess their probability of catching fire in all kinds of real environments, it is essential to have knowledge of the fire performance of these combustions when exposed to various sources of heat. Although much has been reported about the knowledge of many flammable liquids in aviation, the data obtained is scattered across a large number of publications. Therefore, at the request of the Air Force, this book was prepared
