ACCOMPLISHMENTS AND CHALLENGES IN SOLID FUEL RAMJETS AND SCRAMJETS
要約
This paper summarizes the main features of solid fuel ramjets (SFRJs) and scramjets based on comprehensive theoretical and experimental studies. The main accomplishments and challenges are highlighted. Solid fuel ramjets and scramjets are the simplest airbreathing engines. They can provide propulsion solutions in the supersonic and hypersonic flight speed ranges, respectively, with substantially superior energetic performance to that of rockets. This paper presents theoretical and experimental results on the characteristics and performance of solid fuel ramjets and scramjets, emphasizing their particular potential use for increased-range gun-launched projectiles. Efficient combustion in miniature (5−10 mm internal diameter) SFRJ combustors as well as self-sustained supersonic combustion in scramjet combustors is demonstrated. One of the main conclusions is once sufficient specific thrust can be obtained, the solid fuel scramjet may be the most straight-forward hypersonic airbreathing propulsion means to be implemented.
