Research on Development of Foreign Integral Solid Rocket Ramjet Engine Technology

Abstract

Missile power plant is a key factor in determining the missile’s range. This paper analyzes and discusses the current patented technologies and application status of integrated solid rocket ramjet engines in foreign countries (USA, Russia, Europe). Based on the analysis, the key technologies for the development of integrated solid rocket ramjet are summarized, mainly including gas flow regulation and control, high-energy oxygen poor propellant, thermal strength of structure and long-term thermal protection, wide range adjustable intake and exhaust, integrated aerodynamic shape design of missile and engine, etc.
