摘要:
对面关机针栓式喷注器发动机头部的传热情况进行了分析建模，应用数值方法分别计算了发动机在工作过程和关机后头部集液腔内推进剂温度的瞬态变化情况。计算结果表明，发动机在工作过程中头部集液腔中的推进剂温升很小，关机后推进剂有不超过200℃的温升。从计算结果来看，头部的推进剂处于安全的温度范围内。
Abstract:
In this paper, the heat transfer condition of a FSO（Face Shut Off） pintle injector engine head is analyzed and modeled with numerical method. The instantaneous temperature states of the propellant in the engine head during working and shut-off states are computed. The results show that the rise amplitude of the propellant temperature is small when the engine is at work, and the propellant temperature rises less than 200℃ after the engine is shut-off. The conclusions above show that the propellant in the engine head is at a safe temperature range.
