摘　　要：针对超燃冲压发动机再生冷却系统运行条件,实验研究了大庆RP-3煤油的比热容热物理性质。为了检验实验装置的可靠性和准确度,测定了纯水的定压比热容,经与文献值进行比较,测量偏差小于1%,在流动型比热实验台上测量了常压下航空煤油RP-3的定压比热容,温度范围为253 K^393 K,并将实验数据与文献值进行对比,偏差在1%之内。In view of the scramjet regenerative cooling system operating conditions,the experiment studied the specific heat capacities of kerosene RP-3. In order to test the reliability and accuracy of experimental device,we measured the specific heat capacities of pure water at constant pressure,by comparing with the literature values,the measurement deviation is less than 1%. Based on the flow type heat experiment,we measured the specific heat capacities of kerosene RP-3 at constant pressure and temperature range of 253 K ~ 393 K,and compare the experimental data with the literature value,deviation is within 1%.
