摘　　要：为了实现用多少供多少的燃料可控的目的,建立了一种加热器燃料供应系统,该系统利用活塞挤压方式向脉冲燃烧风洞的加热器供应气体燃料,在规定试验时间内能供应流量恒定的燃料,系统结构简单,安全系数高。将加热器燃料供应系统运用于600 mm脉冲燃烧风洞并开展实验工作。A new fuel supplying system in CARDC was presented.The system uses a piston to squeeze gas fuel to the heater of pulse facilities.With very simple structure and high safety coefficient,the system achieves the purpose of controllably supplying fuel with needed amount to the heater,and also can feed fuel with constant mass flow rate in the fixed testing interval.The system has been applied successfully to the newly built pulse combustion wind tunnel with a diameter of 600 mm.
