| Abstract: |
| 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. |
