Thruster jet using monopropellant e.g. hydrazine

摘要

This thruster motor relies on catalytic and / or chemical decomposition of a fluid energy carrier, esp. hydrazine. This fuel is transferred through injector tubes into a catalyst-filled decomposition chamber. In a novel arrangement, the injector tubes (11) discharge first into an annular channel covered by, and connected into the decomposition chamber (2, 12), via outlet passages (20). Pref. there are at least three injector tubes (11) in circular arrangement. The annular channel (19) is separated from the catalyst bed (23) by at least one layer of wire fabric (22), which takes the form of an annular screen (22). This is semi-circular in cross section, with its outward curve facing in the direction of flow.
