摘要:
为了研究高氯酸铵(AP)作为氧化剂的几种含硼(B)燃料配方在微小圆管中的点火燃烧特性,借助高速摄影仪和光线光谱仪,并用Grafula软件处理高速图得到燃
速.结果表明:当含硼燃料配方中,B的质量分数为1/2时,燃烧持续、均匀、稳定,燃速是4.25 mm/s;B的质量分数为2/3、3/4、4/5时,后半段燃料被喷出圆管;B的
质量分数为5/6时,反应不能自维持.且随着B的质量分数增大,光谱强度减弱,持续燃烧时间缩短,燃烧最剧烈的时刻提前,反应剧烈程度和燃烧稳定性均降低.因此合
理的含硼燃料配方可以克服微推进系统中推进剂稳定点火和燃烧困难的问题.
Abstract:
In order to study the ignition and combustion charateristics of several boron-containing fuels with ammonium perchlorate as the oxidizer in
mini-tubes, the high-speed camera and the fiber spectrometer were used, and the moving speed was calculated with high-speed image processing
using the software of GRAFULA. The results show that: for boron-containing fuels, when the mass ratio of B is 1/2, combustion is sustainable,
uniform and stable with the burning rate of 4.25 mm/s; when the mass ratio of B is 2/3, 3/4 and 4/5 respectively, the latter half of fuels is
sprayed from tubes; when the mass ratio of B is 5/6, reaction is not continous. And with the increase of the mass ratio of B spectral
intensity weakens, sustainable combustion time shortens, the moment of the most1 dramatic burning advances, and reaction intensity and
stability decreases. So the difficulty of stable ignition and combustion of propellant in micro-propulsion system can be overcomed by the
reasonable prescription of boron-containing fuels.
