Abstract
A gas inlet suitable in particular for use in an ion thruster includes a housing which is made of a gas-tight ceramics material, and an insert which is arranged in the housing and is made of a porous ceramics material. The geometry and pore structure of the insert are such that the insert forms a desired flow resistance for a gas stream flowing through the insert.
Claims15
A gas inlet for use in an ion thruster, comprising:
- a housing made of a gas-tight ceramics material;
- and
- an insert which is arranged in the housing and made of a porous ceramics material, wherein a geometry and pore structure of the insert are configured such that the insert forms a desired flow resistance for a gas stream flowing through the insert.
A method for producing a gas inlet which is suitable in particular for use in an ion thruster, comprising:
- producing a housing green body;
- producing an insert body;
- inserting the insert body into the housing green body;
- and
- jointly baking the housing green body and the insert body, wherein the baking cycle is so chosen that the housing green body sinters to form a housing made of a gas-tight ceramics material, and that an insert arranged in the housing and made of a porous ceramics material is produced from the insert body, the geometry and pore structure of which insert, after baking, is such that the insert forms a desired flow resistance for a gas stream flowing through the insert.
An ion thruster having a gas inlet for use in an ion thruster, the gas inlet comprising:
- a housing made of a gas-tight ceramics material;
- and
- an insert which is arranged in the housing and made of a porous ceramics material, wherein a geometry and pore structure of the insert are configured such that the insert forms a desired flow resistance for a gas stream flowing through the insert.
