Definitions
- the invention relates to a hybrid-electric propulsion architecture for a multi-rotor rotary wing aircraft, an aircraft comprising such a hybrid-electric propulsion architecture and a method of dissipating electric energy in such a hybrid electric propulsion architecture.
- thermoelectric power A hybrid propulsion architecture of an aircraft, commonly called series hybridization, with generation of thermoelectric power is known from the state of the art.
- a hybrid propulsion architecture 10 generally comprises:
- an electric generator 14 coupled to the internal combustion engine so that in operation the internal combustion engine 12 drives the electric generator 14,
- a rectifier 16 connected to the electric generator 14 and configured to convert an alternating current delivered by the electric generator 14 into a direct current, means 18a, 18b, 18c, 18d of the direct current into alternating current,
- 18b, 18c, 18d electric motors 22a, 22b, 22c, 22d connected to the conversion means 18a, 18b, 18c, 18d so that in operation the conversion means 18a, 18b, 18c, 18d power the electric motors 22a, 22b, 22c, 22d in alternating current, and propellers 24a, 24b, 24c, 24d coupled to electric motors 22a, 22b, 22c, 22d so that in operation the electric motors 22a, 22b, 22c, 22d drive the propellers 24a, 24b, 24c, 24d.
- the electrical network 20 generally comprises a high voltage direct current bus (known by the acronym HVDC from the English expression “High Voltage Discret Current”).
- HVDC high voltage direct current bus
- the architecture 10 can also include a storage unit 26, for example a battery, to absorb the excess electrical energy from the HVDC bus or provide additional energy during the transient phases.
- a storage unit 26 absorbs this excess electrical energy in order to protect the components of the HVDC bus.
- an electric propulsion chain composed by the conversion means 18a, 18b , 18c, 18d, the electric motors 22a, 22b, 22c, 22d and the propellers 24a, 24b, 24c, 24d make it possible to fly a multi-rotary wing aircraft.
- An aircraft comprising such a hybrid propulsion architecture is multi-rotors, which makes it possible to have additional degrees of freedom, compared to conventional aircraft, as regards the controllability of the aircraft, for example braking, the strategy of avoidance, the change of direction, or the tilting of the rotors.
- the hybrid propulsion architecture 10 of FIG. 1 also comprises an energy recovery system 28 on the HVDC bus of the electrical network 20.
- the energy recovery system 28 is generally used when the storage unit 26 is fully charged. , and in transient phases, called “regeneration”, that is to say when there is a return of electrical energy coming from the loads located downstream which return towards the storage unit 26 and the electric generator 14 coupled to the internal combustion engine 12. This occurs in particular when a propeller 24a, 24b, 24c, 24d brakes and rejects electrical energy on the HVDC bus.
- the energy recovery system protects the electronic components arranged upstream, such as transistors.
- the energy recovery system 28 generally consists of an electrical resistance 30 converting electrical energy into thermal energy and of a chopper 32 making it possible to define a voltage threshold from the moment when it is useful to absorb the peak voltage. This energy recovery system is therefore a dissipative circuit, since it dissipates electrical energy in a calorific manner.
- the object of the invention is to propose a solution making it possible to remedy at least some of these drawbacks.
- the present invention proposes a management of the electrical energy allowing the elimination of the energy recovery system of the prior art.
- the present invention therefore proposes to lighten the hybrid propulsion architecture by managing the electrical energy of the HVDC bus, so as to eliminate the electrical equipment used to dissipate the “overflow” of electrical energy on the HVDC bus which would have. as a consequence a rise in voltage in a dangerous manner for static components, such as transistors, and passive components, such as filtering or decoupling capacitors.
- the invention relates to a hybrid electric propulsion architecture for a multi-rotor rotary wing aircraft, comprising:
- an electric generator coupled to the internal combustion engine so that in operation the internal combustion engine drives the electric generator
- a rectifier connected to the electric generator and configured to convert an alternating current delivered by the electric generator into a direct current
- HVDC high voltage direct current
- electrical energy storage means connected to the electrical network in parallel to the electrical generator
- propellers coupled to electric motors so that in operation the electric motors drive the propellers
- the architecture being characterized in that the electric generator is a motor-generator, and in operation the internal combustion engine drives the electric generator in generator mode,
- the storage means are configured to recover the electrical energy, in that during a regeneration of electrical energy on the high voltage direct current bus of the electrical network, depending on the state of charge of the storage means, the rectifier is configured to recover electrical energy,
- the electrical generator in that during a regeneration of electrical energy on the high-voltage direct current bus of the electrical network, depending on the state of charge of the storage means, the electrical generator is configured to operate in motor mode so that in operation the electric generator recovers the electric energy.
- the present invention allows a management of the electrical energy allowing the elimination of the energy recovery system of the prior art.
- this architecture allows good regulation of the HVDC bus of the electrical network and good stability, without integrating an energy recovery system.
- the mass of the architecture according to the invention is therefore optimized, and does not depend on the electrical energy which will be dissipated.
- the architecture according to the invention does not include an energy recovery system in the form of a resistive dissipation circuit. This advantageously makes it possible to reduce the weight and the volume of the architecture according to the invention, such a circuit generally being very heavy and bulky.
- the storage means when the state of charge of the storage means is less than 60%, the storage means are configured to recover electrical energy; when the state of charge of the storage means is between 60% and 80%, the storage means and the rectifier are configured to recover electrical energy; and when the state of charge of the storage means is greater than 80%, the electric generator operating in motor mode is configured to recover electric energy.
- the electrical network can be bidirectional. In other words, the current can flow in both directions in the electrical network, for example from the rectifier to the electric propulsion chains, or vice versa.
- the conversion means may comprise one or a plurality of inverters.
- the conversion means and the rectifier can be configured to be current reversible. This advantageously allows power absorption on the HVDC bus, without necessarily needing a dissipative circuit.
- the electric generator can be a synchronous electric machine.
- the electric generator can be an asynchronous electric machine.
- the internal combustion engine can be configured to consume the electrical energy recovered by the electrical generator operating in motor mode.
- the invention also relates to a multi-rotor rotary wing aircraft, comprising a hybrid electric propulsion architecture according to the invention.
- the invention also relates to a method of dissipating electric energy in a hybrid electric propulsion architecture according to the invention, comprising the steps consisting of:
- the recovery of the electrical energy is carried out by the means of storage.
- the state of charge of the storage means when the state of charge of the storage means is intermediate, for example between 60% and 80%, the recovery of the electrical energy is carried out by the storage means and the rectifier.
- the state of charge of the storage means when the state of charge of the storage means is high, for example greater than 80%, the recovery of the electrical energy is carried out by the operating electric generator. in motor mode.
- the method when the state of charge of the storage means is greater than 80%, prior to the step of recovering the electrical energy by the electrical generator operating in motor mode, the method comprises a step consisting in a defluxing of the electric motors. This advantageously makes it possible to directly avoid the reinjection of electrical energy.
- the method when the state of charge of the storage means is greater than 80%, prior to the step of recovering the electric energy by the electric generator operating in motor mode, the method comprises a step consisting in recovering the electrical energy by the rectifier.
- the method when the state of charge of the storage means is greater than 80%, prior to the step of recovering the electric energy by the electric generator operating in motor mode, the method comprises a step consisting in increasing the electrical voltage of the high voltage direct current bus of the electrical network. This advantageously makes it possible to avoid an increase in the electromotive force of the electric motors.

- the electric generator 114 can generate a polyphase, for example three-phase electric current as shown in FIG. 2.
- the rotational speed NI of the rotor shaft of the internal combustion engine 112 connected to the electric generator 114 can be controlled by means of control 102 (EECU, from the English expression "Electronic Engine Control Unit”).

- only one, or more, or all of the electric propulsion chains can regenerate electric energy.
- Step S02 represents a step of acquiring the state of charge of the storage means 126. During this step S02, it is determined whether the state of charge of the storage means 126 is low, intermediate, or high. .
- a low state of charge of the storage means 126 can correspond to a state of charge less than 40%, preferably less than 50%, and more preferably less than 60%.
- An intermediate state of charge of the storage means 126 may correspond to a state of charge of between 40% and 90%, preferably between 50% and 80%, and more preferably between 60% and 80%.

This step S20 is carried out when the storage means 126 are in a state of. intermediate charge, for example when the state of charge of the storage means 126 is between 60% and 80%.
- This step S20 can also be carried out when the storage means 126 are in a thermal state which does not allow full recharging of the storage means 126, that is to say when the storage means 126 are in a thermal state which risks a unnecessary overheating of the constituent elements.
- This step S20 is a management of the high frequency electrical energy so as to allow protection of the static components of the transistor type.
- the term “high frequency” corresponds to frequencies at the level of the currents on the HVDC bus of the electrical network 120 being greater than 1 kHz.
- Absorption of the over-current is carried out by the capacitive components integrated into the storage means 126 on the one hand, and via the rectifier 116 on the other hand.
- the rectifier 116 absorbs the over-current, denoted IR116 in FIG. 2, and converts it into current with a strong reactive component, that is to say into current with a large variation in the current Id received by the rectifier 116 of the generator.
- electric 114 in the Park landmark This has the consequences of degrading the performance of the electric machine, formed by the electric generator 114, by degrading the power factor of the electric machine. This advantageously makes it possible to absorb the excess electrical energy while degrading the efficiency of the electrical machine, but without adding an energy recovery circuit as in the architectures according to the prior art.
- the electric machine and therefore the electric generator 114, can be a synchronous or asynchronous machine.
- the degradation of performance results in voluntary defluxing, that is to say that the magnetic field created in the stator is opposed to the magnetic field of the rotating magnets. This results in a magnetic loss and an increase in temperature at the magnets of the synchronous machine.
- the increase in the intensity Id in the generator increases by a few percent the electromagnetic torque applied to the mechanical transmission, the turbine thus contributing to the absorption of the excess of electric power.
- the performance degradation is due to an increase in slip, i.e. an increase in the difference between the frequency of rotation of the asynchronous machine and the frequency of the stator currents (i.e. the frequency of the currents stator of the asynchronous machine).
- this variation in slip results in rotor heating of the synchronous machine (i.e. heating of the rotor of the synchronous machine) during long phases of absorption of electrical power.

- the electric motors 122a, 122b, 122c, 122d return electrical energy to the HVDC bus of the electrical network 120, this means that the motors electric motors 122a, 122b, 122c, 122d must brake very quickly, or that several electric motors are no longer controlled, that is to say that the torque setpoint of the electric motors is zero and their propeller is still turning, and that at the same time the other electric motors are, on the contrary, in full acceleration. This happens for example when the aircraft has to change direction, or in the case of an avoidance maneuver.
- the electric motors 122a, 122b, 122c, 122d are defluxed, that is to say that the intensity Id or Iq supplied by the electric generator 114 is modified according to the angle of the mark, in order to reduce the electromotive force (known by the acronym FEM) and directly avoid the re-injection of electrical energy.
- FEM electromotive force
- avoiding the reinjection of electrical energy is not always possible in certain cases, for example when the electric motors 122a, 122b, 122c, 122d overheat too much, preventing defluxing, or if a Decentralized control of the electric motors is used making the acquisition of the state of charge of the storage means 126 difficult.
- the management of the electrical energy is carried out by the electrical energy generation part of the architecture 100.
- the parameters of the management of the electrical energy can be the defluxing of the synchronous machine or a variation of the slip.
- the recovery of the electrical energy is carried out by the electrical generator 114 operating in motor mode.
- the quadrant of the electric generator 114 can be changed, by switching it to motor mode, which imposes a torque on the internal combustion engine 112, which thus becomes a consumer of electric energy.
- the voltage of the HVDC bus of the electrical network 120 can be increased, by anticipating the setpoints on the electric motors 122a, 122b, 122c, 122d, and more precisely by increasing the speed of rotation of the rotor shaft of the motor 112 at internal combustion so as to guard against the increase in the electromotive force of the electric motors 122a, 122b, 122c, 122d. This also helps reduce Joule losses.
