A method and apparatus for increasing the propelling force of pulse engine features that the fuel nozzle of pulse explosion engine is arranged in combustion chamber to close jet tube exit, and the fuel is reversely sprayed out to generate a shock wave barrier near the jet tube for preventing the airflow from flowing out of the combustion chamber, resulting in raising the pressure in combustion chamber and in turn increasing the propelling force.

本发明公开了一种提高脉冲发动机推力的方法和装置，它是通过将脉冲爆轰发动机的燃料嘴置放在燃烧室中靠近喷管出口附近，并使燃料逆向喷出，在燃烧室内靠近喷管附近形成一道阻止气流流出燃烧室的激波，激波的作用是使燃烧室压力升高，从而的到较大的推力。同时由于本发明的结构特别的简单，所以实现非常容易，并且工作效果十分显著。

Cultured PC12 cells were incubated with Fluo 3-AM working solution (the final concentration of Fluo 3-AM is 5μmol/L) at 37℃for 45min, followed by 3 times washes with the culture medium. The cultured neurons grown on glass coverslips were placed in a cell chamber on the stage of an inverted microscope.
