| Abstract: | On the basis of study on the burning characteristics of oxygen-poor fuel-rich propellant, such as frequency band and unsta-bility of burning acoustic signal, adopting the weak-signal testing circuit and computer, a new acoustic emission instrument for measuring burning rate of oxygen-poor fuel-rich propellant was developed. The instrument functions include autocontrol, automatic measurement and calculation of parameters, etc. |
| Keywords: | oxygen-poor fuel-rich propellant burning rate a- coustic emission test set |
