摘要
研制了分析脉冲射流动态压力信号的软件,作为评价这种信号的波形特征、频率结构及能量分布的依据。测试分析表明:自激脉冲喷嘴振荡腔室的几何尺寸显著地影响着射流的振荡效果,其有效喷距较普通喷嘴更长、更宽。
In this paper, a software for analysing the test signal of the dynamic pressure has been developed to evaluate the waveform features, frequency structure and energy distribution. It is found that the geometric size of the oscillation chamber of self - excited pulse nozzles has great effect on the results of oscillation and the effective injection distance is much longer and its range is much wider than normal nozzles.
