摘要: |
针对冲压发动机地面试验应用需求,设计了基于燃气加热方式的煤油加热器,通过试验的方法研究了多个因素对其工作特性的影响规律。研究结果表明,该煤油加热器加热能力强,响应时间短,可在线制备超临界/裂解态煤油;其中,燃气温度、流量和煤油流量是影响煤油加热器工作特性的主要因素,通过控制燃气温度和流量可以大范围调节煤油温度,能满足冲压发动机不同试验工况的应用需求。 |

Abstract: |
In order to satisfy the demand of ground tests of ramjet, a kerosene heater based on gas heating was designed, and tests were taken to do research on the influence of several factors on the operation performance. The results indicate that the kerosene heater has a strong ability of heating, less responding time, and it can produce supercritical/cracked kerosene online; the main factors that influence operation performance of kerosene heater are temperature, mass flow rate of gas, and mass flow rate of kerosene. The kerosene heater can accommodate temperature of kerosene in a large range through control of temperature and mass flow rate of gas. Then it can satisfy demand of different status of ramjet ground tests. |
