介绍了水冲压发动机的性能研究。发动机由镁基推进剂和摄入的水的反应提供动力。在这项研究中,固体推进剂,其中包括一个大的百分比镁,粘合剂和少量的氧化剂,被用作水反应燃料。将冷水注入燃烧室作为主氧化剂。为了研究影响发动机性能的因素,在直连式地面试验系统上对某小型试验发动机进行了试验。结果表明:提高总水燃比、沿燃烧室沿着方向增加二次水进气口、提高推进剂中镁含量、减小一次水喷射角度、提高一次水喷射压力均能提高发动机性能。在试验08中获得了最大的发动机性能,并且通过所有试验,确定了用于最佳发动机性能的一组适当的参数和条件
A performance study of a water ramjet engine is described. The engine is powered by the reaction of a magnesium-based propellant and ingested water. In this study, a solid propellant, which consisted of a large percentage of magnesium, a binder and a small amount of oxidant, was used as a hydro reactive fuel. Cold water was injected into the combustion chamber as a main oxidant. A scaled-down experimental engine was tested in a direct-connect ground testing system to characterize the factors influencing the engine performance. The results show that the increasing of total water/fuel ratio, an addition of secondary water intake along the combustion chamber, a larger magnesium content in the solid propellant, a smaller primary water injection angle towards the coming main flow, and a higher primary injection pressure were all able to promote the engine performance. The maximum engine performance was obtained in test 08, and with all tests, an appropriate set of parameters and conditions for the optimum engine performance were determined
