Project 242: Fission fragments direct heating for space propulsion-Programme synthesis and applications to space exploration

摘要

The status and the main results achieved by Project 242 are presented. Project 242 is a programme (funded by AS11999/2002 from an idea of Carlo Rubbia) that studied a new concept of space propulsion motor by using direct conversion of the kinetic energy of fission fragments into increasing of enthalpy of a propellant gas. Project 242 studied the application of this propulsion system to a manned mission to Mars. Preliminary results were very satisfactory and it has been observed that a propulsion system with these characteristics could make the mission feasible. Results for other unmanned missions to the outer solar system are also presented.
