叙述了高燃速丁羟推进剂试片发动机和低燃速丁羟推进剂“锥一柱”形及星孔形装药发动机在旋转条件下的某些实验结果,其中包括:燃速对加速度的敏感性.残渣沉积及加速度阈值等。还与上一阶段所做的低燃速丁羟推进剂试片发动机旋转实验的结果进行了比较,所得结果可供发动机设计和推进剂配方设计参考。
The experimental results of “cone-column” and star-shaped charge engines with high firing rate of butyrolactam and low firing rate of butyrolactone under rotating conditions are described, including the combustion rate versus acceleration Sensitivity. Residue deposition and acceleration thresholds. The results of the engine rotation experiment of the low-burning-rate butyrolactam coupons made in the previous stage are also compared. The results can be used as a reference for engine design and propellant formulation design.
