FIELD: engine building.
SUBSTANCE: present invention relates to an ion engine (1) for propelling space vehicles, containing a tank (2) for the working fluid (3), an emitter (4) for emitting ions (3+) of the working fluid (3), wherein the emitter (4) has one or more protrusions (11) made of a porous material and a base (12) with a first side (121) supporting the protrusions (11) and a second side (122) connected with the tank (2), and an extractor (5) facing the emitter (4) for extracting ions (3+) from the emitter (4) and dispersing said ions, wherein the base (12) is impermeable for the working fluid (3), at least on said first side (121), and has pores (13) or channels (14) for providing the flow of the working fluid (3) from the tank (2) to said protrusions (11).
EFFECT: creation of an ion engine for use in space vehicles.
