【 摘 要 】

Metal additives are used in explosives and solid propellants in order to increase the energeticoutput and effectiveness of the explosives or fuel. Aluminum has been the primary solid fueladditive to solid fuel to improve the combustive properties of propellants. Several other metalsare being considered for explosive material applications, such as reactive materials, reactivefragments, and metalized explosions. It is important to understand the burning characteristics ofthese materials in order to optimize their use. This study focuses on comparing the spectroscopicoutputs of several energetic metals with that of aluminum. Spectroscopic analysis helps developoptical diagnostics for systems involving combustions of advanced metals. A shock tubeexperimental setup was used to ignite the powders, and resultant spectra were recorded. Metalstested include aluminum, boron, magnesium, hafnium, zirconium, titanium, manganese, silicon,strontium, and scandium. Finally, the resultant spectrum of each metal tested is explained, andan analysis on the results was performed.
