<p>Propulsion for a rocket engine is provided by a frozen gas in solid or liquid form 1 that is heated by a heating fluid or a working fluid 2 in the combustion chamber of a rocket 3 to provide thrust. The frozen gas may be carbon dioxide in solid form or nitrogen or hydrogen in liquid form. The heating or working fluid may be water. A cylinder of frozen gas may be fed using springs 4 which provide pressure against a grill (5, figure 2), such that when the heating fluid is injected against the frozen gas 6 it will be turned into gas and consumed and continuously fed by the pressure from the springs. The heating fluid is pumped into the combustion chamber by a pump 7.</p> |
