| 摘要: |
| 本文探讨了在φ90 实验发动机试验中出现的三种现象，即a)药柱与绝热塑料管脱粘；b)p～t 曲线尾部翘起；c)Al2O3 粒子在喉部沉积。推导了估计沉积对压力曲线影响公式(当药柱作端面燃烧时)。提出了克服脱粘和沉积的措施。 |

| Some Problems in the Experiment of φ90 Subscale Engines |
| Wang Rongxiang |
| Abstract: |
| Three phenomenons，occurring in the experiment of φ90 subscale engines，have been studied，i.e，a) unbounding of the grain to plastic tube to insulate; b) rising of the aft section of the pressre-time history，and c) the precipitating of Al2O3 particles on the throat of the nozzle. The paper derives for mulae of estimating the effects of the precipitate on the history as the burning grain is in smoking. The designs to overcome the unbounding and precipitating have been shown. |
