单基发射药燃烧速度与光谱特性的同步测量法
Synchronous Measurement Method for Combustion Rate and Spectral Characteristics of Single Base Propellant
摘要
Abstract
In this study,to gain deeper insight into the combustion characteristics of single-base propellant,a multi-parameter measurement system based on laser diffuse reflection spectroscopy was developed.This system was employed to measure the combustion parameters of both single-base and double-base propellants.As a result,the combustion spectra and burning rates of both propellant types were successfully obtained.The experimental results revealed that within the 250-500 nm wavelengh range,emission peaks of OH*(313.9 nm),CO2*(462.3 nm),and CHO*(421.7 nm)were observed,attributed to the active in-termediates generated during single-base propellant combustion.Meanwhile,in the 500-780 nm range,distinct emission peaks of Na*(588.7 nm),K*(766.8 nm),and Ca*(554.6 nm)were detected,analyzed to originate from residual lignin in nitrocellu-lose.Compared with the burning velocity measurement results from the image and target line methods,the laser diffuse reflec-tion spectroscopy method showed consistent results,with maximum relative errors of 4.17%and 9.97%.Furthermore,the re-sults from double-base propellant combustion parameter measurements indicated that this method is also applicable for the simul-taneous measurement of combustion velocity and spectra of double-base propellants.The developed method possesses feasibility and versatility,enabling non-contact and non-destructive measurement of propellant burning velocity.关键词
