水空两用发动机燃烧室设计

Design and Study of Combustor for Air-water Engine

  • 摘要: 为了配合可以水空两用的发动机,在对原有燃烧室结构的分析改进和融合创新的基础上,设计了一种可以水空两用的燃烧室。该燃烧室的水空两个模型分别采用了航空发动机燃烧室与水冲压发动机燃烧室设计理论与公式。通过对其进行工作原理改进、热力学计算、三维设计及数值模拟,从而得出了燃烧室内部流场的分布图,并对其数值模拟结果进行分析,指出了以后可以改进优化的地方,其最终结果基本达到了预期设计目标。

     

    Abstract: In order to meet the engines that can adapt both on the air and in the water. Based on the analysis of improvement and integration of innovative original structure of the chamber, we designed a new air-water chamber. The combustion chamber model in the water and air were constructed by using chamber design theories and formulas of the combustion chamber and the water ramjet combustion engine. Through the improvement of working principle, thermodynamic calculation, 3D design and Numerical simulation, the distribution of the flow field in combustion chamber can be obtained. Moreover, we also analyzed the results of Numerical simulation and pointed out the room for improvement. The finally result proves that the design goal and desired effect is basically achieved.
