摘要：
The natural frequency and the system frequency equation of the self-excited oscillation paralleled pulsed jet nozzle was deduced by single chamber's transfer function. Based on the Matlab software, its frequency characteristics were analyzed. The result showed that its natural frequency is decided by the single chamber's natural frequency and damping ratio of chamber; its pulse jet frequency decreases with the increasing of two chambers' length ratio and diameter ratio; when two chambers' structure parameters rational, its excitation frequency is higher than the single-chamber nozzle system.
