Abstract:

Scramjet fueled by solid propellant has the advantages of simple structure, convenient storage, fast launch speed and large specific thrust, making them the preferred future hypersonic missiles power with important military application value. In this paper, the current research progress of combustion organization technology for solid fuel scramjet, solid rocket scramjet and solid powder scramjet are reviewed. Firstly, the working principle of three types of typical solid scramjet is introduced. Secondly, the research progress of three types of solid scramjet is analyzed from the perspective of combustion organization technology. Finally, the three types of solid scramjet are summarized and prospected from aspects of engineering application prospect and future development direction.

Key words: solid fuel scramjet, solid rocket scramjet, solid powder scramjet, combustion organization technology, gas-solid two-phase flow
