2111334 9222742 PCTABS00018 With the intention of achieving more stable combustion conditions in solid-fuel ramjets, and particularly in the case of ramjets with spinning application, it is proposed that the inner surface of the ramjet fuel element (8) is provided with raised surfaces, or lands (14), preferably formed from the fuel element material. In one preferred embodiment, the lands (14) are straight and extend parallel with the longitudinal axis of the fuel element and have the same length as the fuel element. The tangential component of the rotating gasflow generated by rotation, forces the peripheral part of the gasflow to pass over these raised surfaces (14), thereby generating standing, stabilizing vortices downstream of the raised surfaces.
