硼点火实验技术研究进展综述OA

Ten existing ignition techniques of boron(B)were classified into four categories:thermal radiation type,pressure shock type,thermal convection type and special excitation type.The advantages,disadvantages and applicable working conditions of each technique were compared and analyzed.The analysis reveals that all existing ignition methods have complementary strengths,and both physical high-temperature shock and chemical oxide layer stripping can realize effective ignition of B-based fuels.Current research has entered a stage of refined performance regulation,and the core bottleneck restricting technological development lies in the difficulty of simultaneously achieving high-precision testing and high-efficiency ignition.On this basis,the future development directions of B ignition experimental technologies are prospected.Follow-up systematic research can be carried out in multiple dimensions including upgrading diagnostic regulation technologies,developing multimodal composite ignition systems,improving ignition energy efficiency,conducting engineering verification under extreme working conditions,perfecting industrial test standards,and establishing an early warning mechanism for experimental safety.Sustained technological iteration and standardized system construction will accelerate the engineering application of B-based fuels and provide strong support for the development of aerospace and national defense power sectors.
