CATALYST CHAMBER WITH A CATALYST BED EMBEDDED THEREIN FOR A MONOPROPELLANT THRUSTER OF A ROCKET ENGINE

The invention refers to a catalyst chamber (10) with a catalyst bed embedded therein for a monopropellant thruster (1) of a rocket engine. The catalyst chamber (10) comprises an inlet (11) having a first cross-sectional area through which a propellant can be introduced into the catalyst chamber (10)...

More Information
Summary:The invention refers to a catalyst chamber (10) with a catalyst bed embedded therein for a monopropellant thruster (1) of a rocket engine. The catalyst chamber (10) comprises an inlet (11) having a first cross-sectional area through which a propellant can be introduced into the catalyst chamber (10) and an outlet (12) having a second cross-sectional area through which the propellant and/or resulting reaction products can be introduced into a combustion chamber of the thruster (1). The outlet (12) is connected to the inlet (11) via a catalyst volume of the catalyst chamber (10). At least one helical wall member (20) is arranged within the catalyst chamber (10) and is dividing the catalyst volume into two or more segments such that an effective length of the catalyst bed of each segment passed through by the propellant and/or its reaction products is larger than a geometrical length (l 10 ) of the catalyst chamber (10) defined between the inlet (11) and the outlet (12) along a direction of extension of the catalyst chamber (10).
