Title: ROCKET ENGINE WITH SOLAR IGNITION
Abstract:
The invention relates to a rocket engine having more secure and better controlled solar ignition, said rocket engine comprising an axisymmetrical propulsion chamber (12) having a neck (12c) where the diameter of said propulsion chamber (12) is smallest, an injection head (11) designed to inject at least one liquid propellant into the propulsion chamber (12), and a destructible tubular guide (40) arranged coaxially in the propulsion chamber (12) so as to channel said propellant downstream of the neck (12c) of said propulsion chamber (12).
