Boeing has patented nuclear powered aircrafts. The engines of these aircrafts include a unique propulsion system.
A stream of pellets containing nuclear material such as Deutrium or Tritium is fed into a hot-stop within a thruster of the aircraft. Then multiple high powered laser beams are all focused onto the hot-spot. The pellet is instantly vaporized and the high temperature causes a nuclear fusion reaction. In effect, it causes a tiny nuclear explosion that scatters atoms and high energy neutrons in all directions. This flow of material is concentrated to exit out of the thruster thus propelling the aircraft forward with great force.
And this is where Boeing has done something extremely clever. The inner walls of the thurster are coated with a fissile material like Uranium-238 that undergoes a nuclear fission upon being struck by the high energy neutrons. This releases enormous energy in the form of heat. A coolant is circulated along the inner walls to pick up this heat and power a turbine which in turn generates huge amounts of electric power. And guess what this electric power is used for? To power the same lasers that created the electric power! In effect, this space-craft is self-powered with virtually no external energy needed.
Soon, tiny nuclear bombs exploding inside a plane may be business as usual.

Abstract
A propulsion apparatus includes a propellant, at least one laser, and a thrust member. The propellant includes a solid surface having a hollow core disposed within the solid surface and a thrust-producing medium disposed within the hollow core. The at least one laser is positioned to vaporize the propellant with at least one laser-beam into a thrust-producing flow. The thrust member is for flowing within the thrust member a thrust-producing flow created by vaporization of the propellant.
