A Trend Analysis and Future Opportunities on the Solid Fuel Ramjet Technology

The development trends of solid fuel ramjet propulsion technology are investigated, focusing on technically advanced countries. Basic research and system application research that began in the 1940s have achieved remarkable results for the purpose of applying various fuels and combustor shapes to ammunition or guided missiles. However, domestic research has remained within a very limited scope compared to the extensive and active research of these advanced countries, and there is no experience in conducting systematic basic research. Accordingly, the research stages and scope of development trends in technically advanced countries were broadly introduced from the beginning of development to the present, and opinions on the direction of domestic research were presented in light of the current status of our research and development.
