Abstract
A fuel grain for a rocket, the fuel grain having a plurality of layers of fuel grain material, each layer comprising a plurality of concentric circular structures of different diameter fused together to form a central opening therein, wherein the fuel grain material comprises an ignitable substance. The plurality of layers are stacked and joined securely to form a cylindrical fuel grain with the central opening of each one of the plurality of layers aligned to form a combustion unit extending axially through the fuel grain and bounded by a combustion surface, and wherein the fuel grain is configured to permit mixing of heterogenous materials to enhance thrust performance.
