Definitions
- the present invention relates to a Hall effect thruster, also called a stationary plasma thruster.
- a Hall effect thruster comprises essentially an ionization and discharge channel with which an anode is associated, and a cathode disposed in the vicinity of the exit of the ionization and discharge channel.
- the ionization and discharge channel is made of insulating material such as ceramic.
- a magnetic circuit and electromagnet coils surround the ionization and discharge channel.
- a neutral gas such as xenon is injected at the rear of the discharge channel and into the cathode.
- the neutral gas is ionized in the ionization and discharge channel by collision with the electrons emitted by the cathode.
- the ions produced are accelerated and ejected by the axial electric field created between the anode and the cathode.
- the magnetic circuit and the electromagnet coils create within the channel a magnetic field which is essentially radial.
- FIG. 2 represents a diagrammatic view in axial section of an example of a Hall effect thruster of the closed electron drift type.
- FIG. 2 shows an annular channel 21 defined by a piece 22 of insulating material, such as a dielectric ceramic, a magnetic circuit 24 comprising external annular pieces 24a and internal 24b, a magnetic yoke 24d arranged upstream. a thruster and a central core 24c connecting the annular parts 24a, 24b and the magnetic yoke 24d.
- Coils 31, 32 make it possible to create a magnetic field in the annular channel 21.
- a hollow cathode 40 is coupled to a xenon feed device to form a plasma cloud in front of the downstream outlet of the channel 21.
- An anode 25 is disposed in the annular channel 21 and is associated with an annular distributor 27 of ionizable gas (xenon).
- a housing 20 protects the entire thruster.
- the magnetic field lines B, the electric field E, the atoms a, the ions i and the electrons e created from the injected ionizable gas are represented symbolically.
- ergol atoms such as xenon are ionized within a confined discharge in channel 21.
- the ions created i are accelerated in an electric field E created by the anode 25 and ejected at the open downstream outlet 26 of the annular channel 21 to generate the propulsive effect.
- An azimuth electronic current of a few tens of amperes is created inside the channel 21 because of the combination of the mainly axial electric field E and the predominantly radial magnetic field B.
- Hall effect thrusters are described in particular in documents FR 2 693 770 A1, FR 2 743 191 A1, FR 2 782 884 A1 and FR 2 788 084 A1.
- Hall effect thrusters have two important limitations in terms of operation.
- a first limitation is the limited lifetime imposed by the erosion of the ceramic discharge channel. Indeed, a portion of the ions created by the engine is accelerated in the discharge channel to the walls of the engine. Given their energy, these ions erode the ceramic of the discharge channel and thus limit the life of the propellant.
- a second limitation lies in the lowering of the engine efficiency and the acceleration of the engine aging for the high specific pulses (Isp).
- the increase of the specific pulse of a stationary plasma thruster is essentially achieved by increasing the discharge voltage Ud. This leads to generating a hotter plasma, strongly interacting with the walls of the discharge channel. In this case, the energy of the electrons increases significantly until levels that are incompatible with the motor channel ceramic are reached. The higher rate of ions also contributes to the increase in the erosion rate of the motor ceramic.
- Hall effect thrusters having a limited specific pulse, which can typically be of the order of 1000 to 2500 seconds.
- translatable discharge channels When the chamber is eroded, the ceramic of the discharge channel is advanced along the axis of the motor. However, this does not solve the problem of limiting high voltage operation.
- Bombardment ionic thrusters are also known which have grids to accelerate the ions and can operate with specific pulses greater than 4000 seconds.
- the implementation of grids however, has a number of disadvantages.
- the object of the present invention is to overcome the drawbacks of known plasma thrusters and more particularly to modify the Hall effect thrusters, or closed-electron drift plasma thrusters, in order to improve their technical characteristics, and in particular to improve the specific impulse and increase the service life with a significant reduction in the erosion of the discharge channel.
- a Hall effect thruster comprising at least one high-pressure gas tank, a pressure regulation module, a gas flow control device, an ionization channel, at least one cathode disposed at adjacent to the ionization channel output, an anode associated with the ionization channel, a power supply unit, an electric filter and coils for creating a magnetic field around the ionization channel, characterized in that it further comprises an additional power supply unit for applying a pulsed voltage between said anode and said at least one cathode and in that the additional power supply unit alternately produces a first discharge voltage (Udmin) during a first duration (t to t - tj / A ) of between 5 and 15 ps and a second discharge voltage (Ud max) for a second duration (tj / A ) of between 5 and 15 ps.
- Udmin first discharge voltage
- Ud max second discharge voltage
- the additional power supply unit alternately produces a first discharge voltage (Ud min ) between 150 and 250 V and a second discharge voltage (Ud max ) between 300 V and 1200 V.
- said first duration (t to t - tj / A ) is between 5 and 10 ps and said second duration (tj / A ) is between 5 and 10 ms.
- the first discharge voltage (Udmin) is between 180 and 220 V and the second discharge voltage (Ud max ) is between 400 and 1000 V.
- the additional power supply unit comprises at least one capacitor.
- the additional power supply unit alternately produces a first discharge voltage (Udmin) and a second discharge voltage (Udm ax ) respectively during a first duration (t to t - 3 ⁇ 4 / ⁇ ) and a second duration (tj / A ) which are substantially equal.
- the coils for creating a magnetic field are fed by said power supply unit and said electric filter independently of the supply of the anode by the additional power supply unit. said electric filter.
- FIG. 1 is a block diagram of the assembly of a Hall effect thruster according to the invention, with its power supply,
- FIG. 2 is a diagrammatic view in axial section showing an example of a Hall effect thruster to which the invention is applicable,
- FIG. 3 shows curves representing, as a function of time, the evolution of the discharge current I and the average density of the gas N in the form of low frequency oscillations for a Hall effect booster to which the invention can be applied
- FIG. 4 is a curve showing an example of the evolution as a function of time of the discharge voltage Ud which, according to the invention, alternately evolves between a high voltage Udm ax and a low voltage Ud min .
- the invention applies to a Hall effect thruster whose structure of principle has been described above with reference to FIG.
- a conventional Hall effect thruster Although often referred to as a "stationary plasma thruster", the operation of a conventional Hall effect thruster is anything but stationary. Several frequency ranges can be considered, ranging from 20 kHz to several gigahertz.
- a conventional Hall effect thruster is essentially characterized by the following phases:
- Figure 3 presents a simplified modeling of the oscillations in a Hall effect thruster.
- FIG. 3 shows the discharge current I as a function of time (curve 1) and the average gas density N as a function of time (curve 2).
- the oscillations of the ionization / acceleration front are clearly distinguished by the spatial oscillation of the neutral density.
- a Hall effect thruster is thus characterized by the alternation of an ionization / acceleration front ejecting the ionized neutrons and a front of non-ionized neutrals filling the thruster discharge chamber.
- the discharge voltage Ud of the thruster is set at a predetermined level high enough to allow the production of hot electrons suitable for good ionization and the acceleration of ions under a high electric field.
- the discharge voltage Ud of conventional Hall effect thrusters is kept substantially constant during operation. As indicated above, the value of this discharge voltage Ud is chosen at a level making it possible to limit the erosion rate of the ceramic of the discharge channel, typically of the order of 300 to 350 volts, but this leads to also to limit the specific pulse obtained.
- the Hall effect thruster according to the invention makes it possible to obtain a high specific impulse without, however, increasing the erosion speed of the ceramic of the discharge channel, or requiring a modification of the mechanical structure of the thruster.
- Hall according to the invention is made to draw the discharge voltage Ud of the thruster to control the propagation of the ionization front / thruster acceleration by reducing the amplitude of the spatial oscillations of the consumption of neutral atoms in the propellant.
- FIG. 4 illustrates the operation of the thruster with a discharge voltage Ud oscillating with time between a low discharge voltage equal to Udmin and a high charge voltage equal to Ud m ax (curve 3).
- the discharge voltage Ud is set to the low value equal to Ud min .
- the discharge voltage Ud is set to the high value equal to Udmax for a time t j / A which may for example be between 5 and 15 ps and more preferably between 5 and 15 ps. and 10 ps, a value close to 10 ps giving good results.
- the total time t to t of a cycle with a high value of voltage Udmax and a low value of voltage Udmin is imposed by the speed of filling of the thruster channel by the neutral atoms and can by for example, be between 10 and 30 ps and more preferably between 10 and 20 ps, a value close to 20 ps giving good results.
- the voltage Ud min can be for example between 150 V and 250 V, more preferably between 180 V and 220 V.
- the voltage Ud max can be for example between 300 V and
- FIG. 4 shows an example of pulsed operation where the durations tj / A and t to t - tj / A for which the discharge voltage is equal to Ud max and Ud min respectively are substantially equal, but this is not the case. is not required.
- the oscillation frequency of the value Ud between the minimum value Ud mi n and the maximum value Ud ma x depends on the fixed voltage Ud max and then itself determines the value of the specific pulse of the thruster.
