ABSTRACT:
A propulsion motor using a fine particulate material, having a heat content, the material being fed to a convergent portion upstream of and adjacent to the throat of a propulsion nozzle. A fluid under pressure is also fed to the convergent portion, to mix with the particulate material. The fluid is heated by the particulate material, increasing volume and speed, the particulate material and the fluid ejecting from the nozzle. A particular use of such a motor would be on the moon, or some other body, where a fine particulate material can be made available locally.
