摘要: 为实现发动机的水空两用,提出了一种新型的多涵道水空两用发动机概念设计。在建立了初步的三维有限元模型的基础上,重点对水中模式的工作情况进行了分析计算,初选金属钠作为水反应燃料,得到了燃料流量、燃烧室压强、推力的变化关系及燃料流量和比冲的变化关系,初步确定了燃料流量的适宜范围,肯定了水中工作条件下的推进效果。使用CFD软件对金属水反应冲压发动机的参数设计进行了模拟分析,确定了最有利于金属水反应和水冲压发动机推进效果的参数选择。初步评定新型水空两用发动机达到了设计目的。
Abstract: In order to realize the air-water engine, a new multi-bypass amphibious engine conceptual design is proposed. The situation of air mode is analyzed briefly based on the establishment of a three dimensional finite element model. The situation of water mode is analyzed and calculated, and determines the metal sodium as the fuel of the reaction of metal and water. The relationships of fuel flow, combustion chamber pressure, thrust, fuel flow rate and specific impulse are obtained. The suitable range of fuel flow rate is preliminarily determined and the effect of propulsion of water mode is affirmed. The simulation of the design parameters of the metal-water reaction engine is conducted with CFD software. The parameter which is the most advantageous to metal- water reaction and the propulsion effect of the metal-water reaction engine is determined. Preliminarily evaluating the design goal of the new air-water engine is achieved.
