1. A propulsion apparatus comprising:
- a propellant comprising;
a solid surface comprising a hollow core disposed within the solid surface and a thrust-producing medium disposed within the hollow core;
a thrust member comprising a cavity;
at least one laser positioned to vaporize the propellant with at least one laser-beam into a thrust-producing flow within the cavity; and
a portion of the thrust member which bounds the cavity, the portion of the thrust member configured to reflect the thrust-producing flow created by vaporization of the propellant, the portion of the thrust member containing a material which undergoes fast neutron fission and energy release upon being contacted by fast neutrons from the propellant.

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.

16. A method of propulsion comprising:
-
vaporizing a propellant with at least one laser-beam, produced by at least one laser, into a thrust-producing flow within a cavity of a thrust member, the propellant comprising a solid surface, a hollow core disposed within the solid surface, and a thrust-producing medium disposed within the hollow core; reflecting the thrust-producing flow, created by vaporization of the propellant, off a portion of the thrust member which bounds the cavity to provide propulsion; and contacting a material contained within the portion of the thrust member by fast neutrons from the propellant to cause the material to undergo fast neutron fission and energy release. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
