WHAT IF you put half-critical lumps of a fissile material on the tips of a fan blade, and spaced other half-critical lumps around the circumference of the fan shroud. Then, when the fan was spun up, neutron flux in the gap between the lumps would heat the air and expel it to power the fan. If the fan is spinning fast enough, the lumps can be cooled after each pulse of neutrons.
