액체 로켓엔진에서 레이저 점화 기술 적용 검토

다국어 초록 (Multilingual Abstract)

Ignition is very important in the safe and stable operation of liquid rocket engines, and a reignition function becomes very crucial for the realization of reusable space launch vehicles. Unlike the conventional ignition methods, the non-intrusive laser ignition allows the spatial control of ignition spots and a relatively simple construction of the system. Most of researches conducted focused on the non-resonant ignition, which is relatively easy to configure among various laser ignition methods. The key research results of laser ignition summarized in this article address the effects of the differences in laser pulse energy, laser wavelength, ignition system configuration type applied to combustion environments and generated pulse type. Suggestions for future research works on the laser ignition are provided for the successful development of reusable launch vehicle liquid rocket engines.
