| 摘 要： | 给出了一种利用高速摄影技术测量旋转条件下底排装药燃速的方法，其测量误差小于０．８％，并建立了燃速增大系数与径向加速度之间的函数关系。从实验得出，当径向加速度达到某一临界限值时才会出现旋转效应。

| Abstract: | By means of high speed photography,a measuring mothod of the burning rate of the base bleed propellant under high speed rotational conditions is presented.Its errors are less than 0.8%.And the relationship between the increasing coefficient of burning rate and the radial acceleration is established according to the measured results.It is obtained through the test that the rotational effect appears only when the radial acceleration reaches a threshold value |
