Definitions
- the present invention relates to a method for managing the thermal rejections generated by an aircraft and to an aircraft cooling device for carrying out said method.
- FIG. 1 schematically shows a cell and a propulsive assembly.
- cell By cell is meant in the broad sense all elements of the aircraft, including the fuselage, wings, empennages, with the exception of propulsion units.
- a propulsion unit is suspended under a wing by means of a mast. More generally, the propulsion unit is connected to the cell via an interface 14 materialized by a dashed line in FIG.
- a propulsion unit 12 comprises a turbomachine 16 equipped with a first engine cooling circuit 18, in which circulates a coolant, especially oil, passing through a first air / oil exchanger 20.
- the turbomachine is supplied with fuel via a fuel circuit 22 extending from a reservoir 24 disposed at the cell.
- cooling sources it is possible to use several cooling sources to cool the oil of the turbomachine, for example by using a second exchanger 26 oil / fuel at the first cooling circuit engine 18 and used the fuel as heat transfer fluid to cool the oil of the turbomachine.
- the propulsion unit 12 may comprise another source 28 of thermal rejection, for example one or more electric generators installed near the turbomachine.
- each engine cooling circuit 30 in which circulates a heat transfer fluid passing through a third motor exchanger 32, in particular an oil / air exchanger.
- the characteristics of each engine cooling circuit namely the characteristics of the fluid to be cooled, for example its flow rate, the characteristics of the exchanger, for example its dimensions, the characteristics of the fluid used to cool, for example its flow, are adjusted. depending on the need for temperature regulation at the source, especially to maintain the temperature of the source below a certain threshold.
- the cell 10 also comprises at least one thermal rejection source 34, and generally several, for example electrical accessories 34, power electronic systems 34 ', an air conditioning system 34 ", avionics 34 '", customer equipment 34"". All of these elements must be temperature regulated to ensure their operation and guarantee the highest availability rate.
- at least one cell cooling circuit 36 is provided.
- the cell comprises two cell cooling circuits 36, 36 'each having an exchanger 38, 38' for cooling the heat transfer fluid circulating in each of the circuits, these exchangers use air to cool the heat transfer fluid circulating in the cooling circuit.
- the cooling requirements for the propulsion units and the cell vary according to the flight and are not necessarily the most restrictive at the same time.
- the air ducts 40 used to convey the air to the exchangers 38, 38 'of the cell are sized for the most restrictive flight phases, namely, the climb, cruise and descent phases which do not are not the most restrictive phases for propulsion systems.
- the exchangers 20, 32, 38, 38 ' are installed in cooling channels 40 or on the surface of certain parts of the aircraft, for example at the nacelles of the propulsion units.
- these exchangers are penalizing in aerodynamic drag of the aircraft, which has an impact on the energy consumption of the propulsion units.
- the constituents of the cell and the constituents of the propulsion units are segregated for safety reasons. Indeed, it must be ensured that a failure occurring at the cell and disrupting the operation of the propulsion units is extremely unlikely.
- FIG. 3 is a diagram illustrating a cooling device of an aircraft according to the invention during the phases of ground operation
- a propulsion unit 112 comprises a turbomachine 116 equipped with a first engine cooling circuit 118, in which circulates a coolant, especially oil, passing through a first exchanger 120 air / oil.
- the fuel temperature must remain below a certain threshold, in accordance with the certification rules and manufacturers' recommendations in order to obtain optimal operation of the turbomachine.
- the propulsion unit 112 may comprise at least one other source 128 of thermal rejection, for example one or more electric generators installed near the turbomachine 116.
- the cooling requirements of the turbomachine or other sources vary according to the flight phases. In the case of the turbomachine, this need is greatest when the aircraft is on the ground. Therefore, the characteristics of the first motor circuit 118, and more particularly of the exchanger 120 are determined when the aircraft is on the ground which corresponds to the phase of flight during which the needs are the most important. Consequently, the cooling capacities of the first motor circuit 118, and more particularly those of the exchanger 120, are not fully exploited during the others. phases of the flight, especially during the phases of climbing, cruising and descent. It is the same for the second engine cooling circuit 130 and the exchanger 132.
- the cooling device of the aircraft comprises at least one exchanger 142 at at least one cell cooling circuit 138 for transferring heat from the heat transfer fluid of the cooling circuit cell 138 to the fuel.
- the exchanger or exchangers 142 are called interface exchangers 142.
- each cell cooling circuit 138, 138 ' comprises an interface exchanger 142, 142'.
- This configuration which makes it possible to obtain a gain in energy consumption respects the rules of segregation between the cell and the propulsion units and does not complicate the interface between the cell and the propulsion units, no new circuit being provided between the cell and propulsion systems.
- Such a pooling is particularly interesting in the context of a so-called "more electric” aircraft architecture, which provides for air conditioning carried out using electric compressors which must be cooled electrical machines and electronics. associated power and heat pumps which must be removed the thermal power captured.
