Definitions
- the present invention relates to the field of aeronautics and more particularly to the electrical actuation of aircraft equipment including mobile equipment such as: a landing gear, a wheel brake of the landing gear, a thrust reverser, a moving flight surface primary or secondary control such as an aileron or a flap...
- mobile equipment such as: a landing gear, a wheel brake of the landing gear, a thrust reverser, a moving flight surface primary or secondary control such as an aileron or a flap...
- Aircraft often include at least a single-phase electrical network and a three-phase electrical network.
- the single-phase electrical network is considered insufficiently powerful to power moving aircraft equipment, such as flight surfaces, thrust reversers, brakes, and landing gear.
- the three-phase electrical network is therefore used for the actuation of mobile equipment by supplying the necessary power to the electromechanical actuators used to move the mobile equipment between their various service positions.
- the architecture of the supply system for these actuators generally comprises a supply line connecting the motors of the actuators to the three-phase electrical network.
- the supply line usually includes:
- the power requirements are in the form of peaks as can be seen in FIG. 1 which represents the power consumed as a function of time for an aileron actuator.
- the power required at the time of power peaks is supplied by the three-phase network so that all the components of the power supply system must be dimensioned to absorb these power peaks. This results in a relatively high weight which is very penalizing for aeronautical applications.
- the object of the invention is in particular to enable the supply of aircraft actuators by limiting the weight on board.
- an architecture according to claim 1 is provided.
- the supercapacitor that provides most of the power needed by the motor during power peaks and the network is only used to supplement it if necessary or to maintain the charge of the supercapacitor or to the power supply. of the engine excluding power peaks.
- the supercapacitor is recharged by the engine in generator mode, when aerodynamic forces are exerted on the mobile equipment associated with the actuator and the downstream conversion device allows to regulate the voltage and the current, on the one hand, at the terminals of the motor when the latter operates in motor mode and, on the other hand, at the terminals of the supercapacitor when the motor operates in generator mode. It is therefore not necessary to dimension the whole of the architecture according to the power peaks but only the part located downstream of the supercapacitor. This results in a gain in weight and, consequently, a reduction in the fuel consumption generated by the propulsion of the aircraft.
- the invention also relates to an aircraft comprising a three-phase on-board electrical network and a single-phase on-board electrical network, the latter forming part of an actuator power supply architecture such as that mentioned above.
- FIG. 1 represents the power consumed as a function of time for an aileron actuator
- FIG. 2 represents the power to be supplied and the power restored as a function of time for a thrust reverser actuator

- FIG. 5 is a schematic view of the actuation system according to a second embodiment of the invention, the downstream conversion device having a structure different from that of FIG. 4;
- FIG. 6 is a schematic view of the actuation system according to a third embodiment of the invention, with a single-phase DC voltage on-board network, the downstream conversion device of the second embodiment and an internal low-voltage bus ;
- FIG. 7 is a schematic view of the actuation system according to a fourth embodiment identical to the third embodiment except that the upstream conversion device is reversible;
- FIG. 8 is a schematic view of the system for actuating aircraft equipment, according to a fifth embodiment of the invention, for a single-phase alternating voltage on-board network;
- Figure 9 is a schematic view of an aircraft according to
- the invention is described here in application to an aircraft A comprising two on-board electrical networks, namely a three-phase electrical network El and a single-phase electrical network E2.
- the three-phase electric network El is for example subjected to an alternating voltage of 115V or 230V and the single-phase electric network E2 is for example subjected to a direct voltage of 28V or 115V according to the embodiments envisaged.
- the aircraft A comprises mobile equipment including mobile flight surfaces V (primary control) and thrust reversers T. Mobile devices are moved between their different service positions by electromechanical actuators 1.
- the aircraft A is provided with an architecture for supplying the electromechanical actuators, an architecture of which the single-phase electrical network E2 forms part.
- the power supply architecture comprises at least one power supply line, generally designated at 100, connecting the single-phase electrical network E2 to an electric motor 2 of each of the actuators 1.
- the circuit of the motor 2 of each actuator 1 is arranged to have a motor operating mode in which motor 1 transforms the electrical energy which supplies it into mechanical energy moving the mobile equipment and a generator operating mode in which motor 1 transforms the mechanical energy which is transmitted to it by the mobile equipment into electrical energy.
- the invention is described here in application to the supply of a single motor; it goes without saying, however, that the supply architecture can be adapted to supply several motors. Such is for example the case when the mobile equipment is moved by several actuators each comprising a motor or several motors of a single actuator.
- the power supply architecture preferably comprises as many power supply lines as there are a set of actuators acting on the same equipment.
- the supply line 100 successively comprises an upstream conversion device 110, an energy storage device 120 connected by an internal bus to the upstream conversion device 110, and a downstream conversion device 130 connected by an internal bus to the energy storage 120 and to the engine.
- the energy storage device 120 comprises supercapacitors 121 and an electronic circuit 122 for managing the operation of the supercapacitors 121.

- the upstream conversion device 110 is arranged to convert the voltage of the single-phase electrical network E2 into a first internal bus voltage to supply the supercapacitors 121 and the upstream conversion device excluding power peak, the first bus voltage internal being single-phase and continuous.
- the upstream conversion device 110 is dimensioned to compensate for a loss of energy from the supercapacitors 121 due to leakage currents and to supply additional energy to the downstream conversion device 130 during energy peaks.
- the downstream conversion device 130 is reversible to provide voltage conversion both when motor 2 is in motor operating mode and when motor 2 is in generator operating mode.
- the downstream conversion device 130 is arranged to selectively have a voltage step-down function and a voltage booster function regardless of the operating mode of the motor 2 so that the supercapacitors 121 can power the motor 2 in motor operating mode and be recharged by the engine 2 in generator operating mode.
- the downstream conversion device 130 is thus arranged to, on the one hand, convert the first internal bus voltage into an alternating three-phase supply voltage of the windings of the motor 2 to drive the motor in motor mode and, on the other part , convert an alternating three-phase voltage supplied by the motor into the operating mode generator to a voltage suitable for recharging supercapacitors 121 .
- downstream conversion device 130 must make it possible to regulate the input and output voltage whatever the operating mode considered: this is particularly advantageous in generator operating mode because it is then possible to lower the voltage. to prevent an overvoltage beyond the maximum voltage acceptable by the supercapacitors 121 or, on the contrary, to increase the voltage to accelerate the charging of the supercapacitors 121 (while remaining below the maximum voltage acceptable by the supercapacitors 121) .
- the single-phase electrical network E2 supplies a low direct voltage of 28V and the first internal bus voltage is a high direct voltage equal to 270V.
- the upstream conversion device 110 is here a step-up DC/DC converter which is sized to convert the single-phase DC voltage of 28V into the single-phase DC voltage of 270V and which is connected to the energy storage device 120 by a internal bus to the first internal bus voltage.
- the downstream conversion device 130 comprises a Buck-boost and more precisely Y-Buck-boost topology inverter as represented in FIG.
- This inverter comprises for each phase of motor 2 a first bridge of transistors T1 and T2 (Buck bridge) having a midpoint connected via an inductor to a midpoint of a second bridge of transistors T3 and T4 (Boost bridge) in parallel with which a capacitor is mounted.
- the inverter is controlled in a manner known per se and for example by implementing the control method described in the document FR-A-3066660.
- the downstream conversion device 130 comprises a DC/DC converter 131 and a step-down inverter voltage 132 both replacing the Buck-Boost type inverter of Figure 4.
- the DC/DC converter 131 is arranged to be a voltage booster, reversible and isolated, and is connected to the energy storage device 121 by an internal bus at the first internal bus voltage, here 270V DC.
- the DC/DC converter makes it possible to regulate the voltage at the terminals of the supercapacitors 121 .
- the DC/DC converter 131 is here of the “Dual Active Bridge” type.
- Step-down inverter 132 is reversible and is connected to motor 2 .
- the DC/DC converter 131 and the step-down inverter 132 are interconnected by an internal bus isolated from the first internal bus voltage, ie here 270V DC.
- the upstream conversion device 110 is, as before, a step-up DC/DC converter which is sized to convert the single-phase DC voltage of 28V into the single-phase DC voltage of 270V and which is connected to the energy storage device 120 by an internal bus to the first internal bus voltage.
- the voltage applied to the supercapacitors 121 is regulated so as not to exceed the maximum voltages and currents supported by the supercapacitors 121;
- the allowable variation in voltage on the internal bus is greatly increased (within the limit of acceptable currents) for the same amplitude of the voltages of the phases of motor 2 in order to reach the speed range sought for the motor.
- the third embodiment of Figure 6 is identical to the second embodiment except in that the energy storage device 120 is connected to the upstream conversion device 110 by an internal bus at a first relatively low voltage, here being 28V continuously and to the downstream conversion device 130 by an internal bus at the first voltage, i.e. 28V continuous.
- the conversion device 110 and the DC/DC converter 131 are adapted to these voltage values.
- the DC/DC converter 131 is arranged to be a voltage booster, reversible and isolated, and is connected to the energy storage device 121 by an internal bus at the first internal bus voltage, here 270V DC.
- the DC/DC converter 131 is arranged to greatly raise the voltage to supply the inverter 132 in motor mode and to regulate the voltage across the terminals of the supercapacitors 121 in generator mode.
- the DC/DC converter 131 is here of the “Dual Active Bridge” type.
- the galvanic isolation of the DC/DC converter 131 makes it possible to provide a barrier between the supercapacitors 121 and the motor 2 to avoid an uncontrolled supply of energy to the motor 2 . It also makes it possible to generate a very low DC voltage on the inverter 132 to verify its operability before it is used (“power built in test/in flight test”).
- the upstream conversion device 110 is connected to the energy storage device 120 by an internal bus at a first relatively low voltage, here being 28 V continuously and is arranged to be reversible and have a voltage step-down function and a voltage step-up function to authorize distribution of energy from the supercapacitors 121 to the single-phase electrical network E2.
- the downstream conversion device 130 includes a DC/DC converter 131 and a step-down inverter 132.
- the DC/DC converter 131 is arranged to be a voltage booster, reversible and isolated, and is connected to the energy storage device 121 by an internal bus at the first internal bus voltage, here being 28V DC.
- the step-down inverter 132 is reversible and is, on the one hand, connected to the motor 2 and, on the other hand, connected to the DC/DC converter 131 by an isolated internal bus at a second relatively high internal bus voltage either here 270V continuously.
- the single-phase electrical network E2 delivers an alternating voltage of 115V and the upstream conversion device 110' comprises a half-wave passive rectifier or a power factor correction rectifier.
- the rest of the supply line 100 is identical to that of Figure 3.
- the supercapacitors 121, the circuit 122 for managing the operation of the supercapacitors 121, the upstream conversion device 110, 110' and at least part of the downstream conversion device 130 are part of the same electronic device incorporating at least one processor.
- the actuation sequence comprises:
- the supercapacitors 121 are sized so as not to be fully charged during the flight time of the aircraft, the complete recharging of the supercapacitors being ensured during the second driving phase. This is valid for any application implementing an actuation sequence beginning with a generating or driving phase of relatively low power followed by a generating phase.
- an energy dissipation resistor connected to the downstream conversion device will preferably be provided to dissipate the energy produced when the motor is in generator operating mode and that the supercapacitors are saturated.
- the power supply architecture may have a different structure from that described.
- the downstream conversion device may comprise a converter having a Boost, Buck-boost, Cuk, etc. topology.
