摘要
Abstract
The boron-loaded gel propellant,made by adding boron powder,gelling agents and other modified sub-stances into liquid fuel,is an ideal fuel providing power for limited volume propulsion devices such as ramjets.How-ever,the application of boron-loaded gel propellant also brings new technical challenges such as preparation of high-boron-content gel propellant with excellent stability and rheological properties,controllable supply and efficient atomiza-tion of propellant,and efficient combustion organization of ramjets.The development history of boron-loaded gel pro-pellant and related research work are summarized,and the atomization technology of gel propellant is introduced in detail.On the basis of integrating a large number of research achievements,the problems that still need to be further studied are presented.The combustion characteristics of single droplets and spray of boron-loaded gel fuel are sum-marized,the research work on boron-loaded gel ramjets at home and abroad reviewed,and the combustion organiza-tion characteristics of boron-loaded gel ramjets introduced.Finally,the research direction of boron-loaded gel ramjets is summarized.关键词
