垂直发射装置中压力振荡与温度振荡的相互作用

The Effects between Pressure Oscillation and Temperature Oscillation in VLS

对垂直发射装置燃气流的低频不稳定性进行了分析，给出了压力振荡与温度振荡二者之间数学表达式，并给出了定性的实验证明本文首次测得了燃气流温度整体振荡。

An analysis is presented in which the instability known as low-frequency of hot gas flow is studied in the vertical launching system.A mathematical model is obtained about the relationship between pressure oscillation and temperature oscillation and a quantitative experimental result is given.These experimental data about the temperature perturbation of low-frequency whole oscillations are first obtained in the experiment .It shows that it is not light considering whole oscillation as equal temperature.
