Problems solved by technology

However, the manipulation of thrust through the uneven flow rate of the gas injected into the annular channel described in these documents is relatively ineffective and even frustrating considering the additional complexity introduced by the flow regulator device

Embodiment Construction

[0027] figure 1 , Figure 1A with Figure 1B Different views of the same Hall effect thruster 1 in one embodiment are shown. The propeller 1 has an annular channel 2 delimited by two concentric walls 3, 4 around a central axis Z', these concentric walls being made of ceramic material. The annular channel 2 has an open end 5 and a closed end 6 . Next to the closed end 6 , radial walls 7 subdivide the upstream section 2 a of the annular channel 2 into separate compartments 8 . At the closed end 6 the annular channel 2 also has an anode 9 which can be separated from a plurality of compartments 8 and a nozzle 10 for injecting propellant gas into each compartment 8 . The nozzles 10 are connected to a source of propellant gas through an injection circuit 11 comprising individual flow rate regulator means 12 for each nozzle 10 . For example, each device 12 may be a pencil valve or a thermo-capillary; a thermo-capillary is a capillary with heating means to actively control its ow...

Abstract

A steerable-thrust Hall effect thruster in which a final stage of a magnetic circuit includes an inner pole and a facing outer pole, the inner pole being offset axially downstream relative to the outer pole, so that a magnetic field is inclined relative to a transverse plane of the thruster.

Description

technical field [0001] The present invention relates to the field of Hall effect thrusters. [0002] The present invention more particularly relates to a steerable thrust Hall effect thruster having an annular channel, an anode, an injection circuit, a magnetic circuit and a cathode. The annular channel is defined by two concentric walls having a central axis, has an open end and a closed end, and includes an upstream section adjacent to the closed end, which is subdivided by radial walls into a plurality of separate compartments . The anode is located at the closed end of the annular channel. The injection circuit is adapted to inject propellant gas, such as for example xenon, into the compartments of the annular channel and comprises at least one independent flow regulator means for each compartment. The magnetic circuit is adapted to form a magnetic field at the open end of the annular channel. The cathode is located outside the open end of the annular channel. [0003...
