摘要
提出一种改进型变通道内燃星形装药，它在结构尺寸上分作两段：前段等肉厚等通道，后段变肉厚变通道。它具有燃面变化平缓、侵蚀效应小、残药少的优点。
modified star-shaped grain configration is presented, with consists of two sections: the front section has a cross-section-constant port with constant web thickness, while back section has a variable port with variable web thickness. The grain features of smoothly varying burning surface, less erosive burning, and less slivers are obtained.
