摘要

根据平行层燃烧理论,推导了多种药型燃烧面积随燃去肉厚的变化规律。分析了星孔型药柱、车轮型药柱、套管型药柱和短管型药柱的减面性。结果表明,星孔型药柱和车轮型药柱的减面性大,且减面性可调范围大,套管型药柱和短管型药柱的减面性小。减面性较小时,优先选用短管型药柱。星孔型药柱的星角数和车轮型药柱的轮臂数相同时,相同的减面性,星孔型药柱的装填系数和肉厚系数都大于车轮型药柱。减面性较大时,优先选用星孔型药柱。

Abstract

Based on geometrical law of burning, the discipline of burning area changing with burned web thickness for variety of grain types was deduced. The regressive burning of star-shaped grain, wheel-shaped grain, sleeve-shaped grain and short tubular grain was analyzed. Results show that the regressive buring of star-shaped grain and wheel-shaped grain are larger, and the adjustable range of the degression buring is large. Regressive burning of sleeve-shaped grain and short tubular grain is smaller. When the degressive nature is small, the short tubular grain is selected preferentially. When the star angle of the star-shaped grain and the wheel arm of the wheel-shaped grain have the same number, further more, they have the same regressive burning; the filling factor and web thickness of star-shaped grain will be larger than wheel-shaped grain. When degressive nature is large, star-shaped grain is selected preferentially.
