The combustion efficiency of hybrid rocket motor is very low. In order to increase combustion efficiency, we can use vaporization chamber and mixing chamber.
混合发动机燃烧效率比较低，使用预燃室和补燃室、合理设计喷注器以及采用扰流装置，可以提高燃烧效率；

In this paper, we present a new type of hybrid arc quenching system, which controls the metal vapor and back flow of the hot air in splitters arc quenching chamber.
The property of the hybrid active silencer relies on the equivalent impedance at the secondary sound source position and the impedance distribution characteristics of the one-chamber pipe itself.
