| 摘 要： | 在一次燃气参数及总水燃比相同的情况下,研究了进水方式对水冲压发动机性能的影响,所得结论得到了试验结果的部分验证。研究表明,要使发动机获得较高比冲,进水方式的设计至少应该遵循两个原则——一次进水流量和活性铝粉流量接近1∶1;后部进水位置尽量靠前,以使所有水雾都能完全蒸发。

| Abstract: | The effects of water spray mode on water ramjet performance were studied under the same fuel gas parameters and to-tal water fuel ratios conditions. The conclusions were validated partially by the test data, The results show that at least two principles should be obeyed during designing the water spray mode for obtaining higher specific impulse, namely,mass flow ratios of H_2O and Abstract should be nearly 1: 1 ,and rear water spray location should be possibly close to head so as to make water fog evaporated com-pletely. |
