Definitions
- TITLE Process for regulating a turbomachine Technical field of the invention
- the present invention relates to a turbomachine for an aircraft, in particular the regulation of a turbomachine using electrical assistance.
- the turbomachine 100 similar to that described in document FR 3087491, as shown schematically in FIG. 1, is known of the turbofan and twin-body turbojet type for aircraft.
- the turbomachine 100 comprises, from upstream to downstream in the direction of the flow of the gases F, a fan 110, a low pressure compressor 111, a high pressure compressor 112, a combustion chamber 113 which receives a fuel flow setpoint , a high pressure turbine 114, a low pressure turbine 115 and a primary exhaust nozzle 116.
- the low pressure (or LP) compressor 111 and the low pressure turbine 115 are connected by a low pressure shaft 121 and together form a lower body pressure.
- the high pressure (or HP) compressor 112 and the high pressure turbine 114 are connected by a high pressure shaft 122 and together form, with the combustion chamber, a high pressure body generating hot gases.
- the BP 121 shaft and the HP 122 shaft do not generally rotate at the same speed and they do not have the same inertia. Consequently, especially in the acceleration phases, the LP compressor 111 (we talk about N1 speed) accelerates more slowly than the HP 112 compressor (we talk about N2 speed), partly because of their different inertia. A situation is then obtained where the LP compressor 111 compresses more air than the HP compressor 112 can receive. This situation creates a risk of surge in the area of the LP compressor
- This phenomenon corresponds to significant and rapid fluctuations in the pressure downstream of the compressor concerned. Pumping once initiated can lead to flameout of the combustion chamber. It also generates significant jolts on the blades of the compressor and can thus lead to mechanical damage.
- the design of the turbomachine 100 requires taking into account a sufficient margin against the surge phenomenon.
- the operation of a compressor in use is generally represented by a diagram which expresses the pressure ratio obtained between the outlet and the inlet, as a function of the air flow which passes through it; this diagram is also parameterized according to the rotation speed of the compressor.
- This diagram shows a pumping line which constitutes the maximum limit in terms of the compression ratio not to be exceeded, so as not to risk the appearance of a pumping phenomenon.
- a so-called operating line is defined, associating the compression ratios obtained as a function of the fuel flow, when the turbomachine 100 is in stabilized operation.
- one solution consists in using hybridization of the HP 122 shaft by providing torque produced by an electric motor to regain the acceleration performance in N2 regime of the HP 122 shaft while limiting the flow fuel.
- this document proposes a method for regulating a turbomachine comprising a high pressure turbine connected to a high pressure shaft and a low pressure turbine connected to a low pressure shaft, hot gases at the outlet of the high pressure turbine driving the low-pressure turbine, the method comprising: a- electrically assisting the high-pressure shaft by means of an electric machine, to supply said high-pressure shaft, mechanical energy resulting from the electric energy supplied to the electric machine in addition thermal energy from a combustion chamber of the turbomachine, for a duration of assistance, and b- correcting the speed of the low pressure shaft to reach a reference speed of the low pressure shaft previously determined in the absence of electric assistance.
- the process makes it possible to limit the loss of acceleration of the low pressure shaft during the electrical assistance phases of the high pressure shaft.
- the method makes it possible to compensate for the loss of acceleration suffered during the electric assistance phase so that at the end the acceleration time of the BP shaft is the same as for non-hybrid acceleration or without electric assistance. .

- the electric machine can be controlled to take the mechanical torque calculated in step b2 to brake the high pressure shaft. This has the effect of increasing the fuel flow to be supplied to the combustion chamber of the turbomachine to maintain the speed of the high pressure shaft at a set speed level, in particular to respect an acceleration trajectory of the high pressure shaft.
- the reference power of the hot gases can be determined beforehand for a plurality of instants of operation of the turbomachine, in the absence of any electrical assistance from the high pressure shaft. This determination can be carried out experimentally or by simulation.

- the correction coefficient can be determined as a function of the speed of the high pressure shaft at a time of operation of the turbomachine and a corrected speed of the high pressure shaft
- the corrected speed of the high pressure shaft can be determined according to the following operations:
- the corrected speed of the high pressure shaft can be configured to produce at each operating moment a power of hot gases during the electric assistance equivalent to a power of hot gases for the same speed of the high pressure shaft in the absence of electric assistance.
- the correction coefficient may be the ratio between the corrected speed of the high pressure shaft and the reference speed of the high pressure shaft in the absence of electric assistance.

- the method 200 comprises a first step 202 of electric assistance by supplying a mechanical assistance torque generated through the HP electric machine to the HP shaft 122.
- the turbomachine 100 can comprise an electric motor M forming a device making it possible to supply a mechanical assistance torque G HR to the high-pressure shaft 122 during the electrical assistance phases t asS ist.
- the duration of assistance t aS sist is determined so as to limit the flow of fuel to avoid any pumping phenomenon.
- the duration of assistance t aS sist can correspond to the time spent by the turbine engine 1 in abutment of operability to protect against the surge phenomenon.
- the mechanical assistance torque generated by means of the electric machine G HR is determined to respect a predetermined trajectory of acceleration of the speed N2r of the HP shaft 122.
- the method 200 then comprises a step 204 of determining an energy deficit E d of the BP shaft 121.

- Step 204 then comprises the calculation of the energy deficit E d by block 24 as a function of the power differences P def obtained during the assistance duration t asS ist.
- Block 24 consists of integrating the power differences P def over the assistance duration t asS ist.
- the method then comprises a step 206 of determining a mechanical torque to be taken by means of the electric machine G HR3 at the level of the HP shaft 122 making it possible to make up for the delay in the speed N1r in the presence of electric assistance with respect to the reference N1r diet.
- Step 206 firstly comprises the determination of an average additional power P core s u Vmoy to be supplied, to reach the reference speed N1r at a predetermined time t 0bi as a function of the energy deficit E d .
- the average additional power is calculated by the following formula:
- a power P CO re sup corresponding to an instantaneous power to be supplied between t aS sist and t 0 bj is then determined to ultimately produce the average additional power p core s, relieve u ⁇ Pmoy at the level of shaft BP 121 at t 0 bj.
- the power P core s, TM up can be provided simply as a step, or else in a more complex way, for example following a ramp, a polynomial, etc.
- the mechanical torque to be taken off by means of the electrical machine G HR3 is determined as a function of the power P CO re sup according to a pre-established law such as that represented by the curve C1 of FIG. 2b.

- the fuel flow Wfreq is determined according to the mechanical assistance torque generated by means of the electric machine G HR and the set point N2cmd of the speed of the HP 122 shaft.
- the mechanical assistance torque generated by means of the supplied G HR electric machine makes it possible to reach the N2cmd setpoint of the HP 122 shaft speed without inducing pumping but causes a power deficit of the hot gases at the high turbine outlet pressure and therefore an acceleration delay of the BP shaft 121.
- the method 300 comprises a step A-300 to correct the trajectory of the setpoint N2cmd according to the mechanical assistance torque generated by means of the electric machine G HR and the speed Current N2r from HP 122 shaft.
- Step A2 comprises a sub-step A321 of determining a correction coefficient K corr as a function of the current N2r speed of the HP shaft 122 and of a corrected speed N2r corr of the HP shaft 122.
- the correction coefficient K corr is the ratio between the current N2r speed of the HP shaft 122 and the corrected speed N2r corr of the HP shaft 122, calculated for example by the following formula:
- the corrected speed N2r corr of the HP shaft 122 is determined as a function of the current N2r speed of the HP shaft 122 and by consulting the databases 302 and 304 previously defined.
- the database 302 comprises the values of the power of the hot gases P core as a function of the speed N2r of the HP shaft 122 and of the mechanical assistance torque generated by means of the electric machine G HR .
- the database 304 comprises the values of the speed N2r of the HP shaft 122 as a function of the power of the hot gases P core and of the mechanical assistance torque generated by means of the electric machine G HR .
- Database 304 includes the inverse function of database 302.
- the databases 302 and 304 can be determined experimentally or by digital simulation depending on the characteristics of the turbomachine 100.
- the database 302 is first consulted to determine the reference hot gas power P C ore nom for the current N2r speed of the HP shaft 122 for a mechanical assistance torque generated through the electrical machine G Zero HR .
- the database 304 is then consulted to determine the corrected regime N2r corr to produce the reference hot gas power P C ore nom
- the corrected N2r corr is obtained as a function of the reference hot gas power P CO re nom and the mechanical assistance torque generated by means of the electric machine G HR supplied at the end of step D-300.
- Step A-300 comprises a sub-step A322 for determining the setpoint N2cmd of the speed of the HP shaft 122 by correcting the acceleration trajectory 306 of the speed N2r by the correction coefficient K corr , for example by multiplying the acceleration trajectory 306 of the regime N2r and the correction coefficient K corr .
- Step A2 thus makes it possible to modify the acceleration trajectory of the HP shaft 122, then causing the speed N1r of the LP shaft 121 to follow the curve C′ of the corrected speed N1r.
- Curve C' of the N1r speed approaches curve A of the reference N1r speed from the start of the assistance phase t asS ist.
