The tests were conducted in the hypersonic low density wind tunnel at nominal test conditions of mach 16, stagnation temperature 923k, stagnation pressure 1. 40mpa and 7. 30mpa. heat - transfer data were obtained on a hemisphere model, a sharp cone and a big blunt cone respectively by means of infrared thermal mapping techniques, that of a 0. 5mm thickness blunt cone by virtues of thermocouples. furth ermore, heat - transfer on all those models was calculated with the theoretical method
最後在名義m _ = 16 、 t _ 0 = 923k 、 p _ 0 = 1 . 40mpa及7 . 30mpa的高超聲速低密度風洞中，利用紅外熱圖技術獲得了半球圓柱、尖錐、大鈍頭三個模型表面熱流分佈，利用薄壁法技術得到了一壁厚為0 . 5mm的鈍錐模型表面的熱流分佈，並通過工程理論方法計算了模型表面的氣動熱，把理論計算結果與上述試驗結果比較，幾者符合得較好。 -
The results show that, for reynolds number of 4400 ~ 23800, heat transfer coefficients at stagnation point always increase with the increasement of reynolds number ; the average deviation of heat transfer coefficients at stagnation point from published results is about 10. 8 %, which shows the system is reliable for temperature measurement
實驗結果表明，在re = 4400 28300范圍內，駐點區換熱系數隨雷諾數的增大而增大；駐點區換熱系數與前人的實驗結果相比平均誤差10 . 8 ，實驗系統具有很好的可靠性。
