Abstract

A fuel grain is disclosed that comprises a core having a longitudinal axis and at least one internal aperture substantially aligned with the longitudinal axis wherein the core comprises a fuel composition comprising first and second fuel components. In some embodiments, the ratio of the first fuel component to the second fuel component at a first position relative to the longitudinal or latitudinal axis is greater than the ratio of the first fuel component to the second fuel component at a second position relative to the longitudinal axis or latitudinal. In another embodiment, the fuel grain comprises a fuel composition that includes less than 1 ppm sulfur. Some compositions use a Fischer-Tropsch wax as one or more of the fuel composition components. Methods of making such fuel grains are also described.
