Abstract:

Adding energetic solid particles, such as aluminum and boron, into liquid hydrocarbon fuel is an effective approach to improve the energy characteristics of the fuel, and it is also an important technological base in improving the performance of rocket engine and ramjet in the future. In this paper, the development and current demand of energetic hydrocarbon fuels are introduced, and two types of energy-containing hydrocarbon fuels and their respective advantages are analyzed and compared. Besides, the single droplet combustion experiments of hydrocarbon fuel containing solid particles at home and abroad are reviewed. The characteristic combustion process and typical combustion phenomena of energy-containing hydrocarbon fuel droplets are introduced. In addition, the application progress of energetic hydrocarbon fuels in rocket engine, ramjet and scramjet are summarized. Finally, the future research of hydrocarbon fuels containing solid particles is prospected.

Key words: solid particles, energetic hydrocarbon fuel, single droplet combustion, rocket engine, ramjet engine
