The forward variable area bypass injector (FVABI) is a key component of double bypass variable cycle engine (VCE) to achieve mode transition and bypass ratio adjustment. In this paper, an experimental system for FVABI was constructed based on the analysis of relevant experimental theories, and then the experiments on FVABI were carried out for a specific working state in double bypass mode of VCE and for the comparison working states with different area ratios and different back pressure ratios. The results showed that the FVABI designed in this paper meets the requirements of VCE at this working state. The analysis of the influence of area ratio and back pressure ratio on the injection coefficient showed that the first bypass valve and back pressure were effective means to control the mass flow of FVABI.

变速发动机前可变面积旁通喷油器性能的实验研究

前可变面积旁路喷射器(FVABI)是双旁路可变循环发动机(VCE)的关键组件,可实现模式转换和旁路比调节。本文在对相关实验理论进行分析的基础上,构建了FVABI实验系统,然后针对VCE双旁路模式下的特定工作状态进行了FVABI实验,并比较了不同面积比的工作状态。和不同的背压比。结果表明,在此工作状态下,本文设计的FVABI符合VCE的要求。分析面积比和背压比对喷射系数的影响表明,第一旁通阀和背压是控制FVABI质量流量的有效手段。
