Description

Technical Field

[0001] This application relates to the field of airborne fuel supply and low-carbon emission control technology for aero-engines, and in particular to a method and apparatus for blending multi-component sustainable aviation fuel on an aircraft. Background Technology

[0002] As the global aviation industry accelerates its decarbonization process, SAF (Sustainable Aviation Fuel) has become a core pathway to reduce carbon emissions. Compared to traditional jet fuels, SAF can reduce carbon emissions by up to 90% and can be used directly in aircraft turbine engines or blended at a ratio of 1% to 50%, without requiring modifications to existing aviation infrastructure. However, the large-scale application of SAF faces multiple challenges, including the coexistence of diverse technological approaches, complex blending requirements, high costs, and compatibility with existing engine systems. Existing technological systems exhibit significant bottlenecks in addressing these challenges.

[0003] In related technologies, a ground-based premixing method is used to achieve fuel blending. Before refueling the aircraft, SAF (Salicylic Acid Fuel) and conventional aviation kerosene are physically blended on the ground in storage tanks or specific devices. This method typically only supports mixing the two fuels at a preset, fixed volume ratio. The blended fuel is then uniformly added to the aircraft's fuel system for use throughout the flight. However, this method has significant limitations in actual operation. The fixed blending ratio cannot be dynamically adjusted according to the different operating conditions of the aircraft at different flight stages, and it is difficult to adapt to the blending requirements of multi-component SAF. The blending accuracy is easily affected by the ground storage environment, making it difficult to meet the industry accuracy standards for aviation fuel blending. The fixed blending ratio cannot adapt to the differences in operating conditions throughout the entire flight cycle, which not only makes it difficult to optimize the emission reduction effect throughout the flight but also leads to poor emission reduction performance under high emission conditions. It also has poor environmental adaptability, easily affected by environmental factors such as temperature and humidity, resulting in fuel stratification problems. Long-term storage can also cause deviations in the physicochemical properties of the fuel.

[0004] However, the related technologies, due to their ground-based premixing mode, cannot adapt to the dynamic requirements of multiple airborne operating conditions and lack the ability to flexibly adjust multiple components. This makes it difficult to match the differences in physicochemical properties of diverse SAF technologies (such as HEFA (Hydroprocessed Esters and Fatty Acids), e-SAF (electro-Sustainable Aviation Fuel), methanol-to-jet fuel, etc.). Because a dynamic correlation model of "operating condition-blending ratio-emission" has not been established, it is impossible to achieve emission reduction optimization throughout the entire flight cycle. The lack of a real-time temperature, humidity, and pressure control mechanism results in insufficient environmental adaptability, a contradiction between emission reduction and economic efficiency, and a lack of a real-time emission data feedback and correction mechanism, which urgently needs improvement.

[0035] Before introducing the method for blending multi-component sustainable aviation fuel on airborne vehicles according to the embodiments of this application, the system for blending multi-component sustainable aviation fuel on airborne vehicles involved in the embodiments of this application will be introduced first.

[0036] Specifically, Figure 1This is a schematic diagram of the structure of an airborne multi-component sustainable aviation fuel blending system provided according to an embodiment of this application.

[0037] The aircraft's onboard multi-component sustainable aviation fuel blending system adopts a three-stage-two-stage-one-stage fuel tank structure, specifically including: a three-stage feedstock fuel tank, a two-stage blending fuel tank, a one-stage blending fuel tank, and auxiliary control components.

[0038] The three-stage feedstock tank system comprises 3-5 independent tanks, each storing different types of fuel, including but not limited to: HEFA sustainable aviation fuel (low calorific value 43-44 MJ / kg, low emissions, cost $1200-1500 / ton), CO2-synthesized e-SAF (carbon emission reduction ≥85%, cost $2500-3000 / ton), methanol-to-jet fuel (jet fuel selectivity 60%-70%), conventional JetA-1 jet fuel (cost benchmark, higher particulate emissions), and biodiesel derivatives. Each tank is equipped with an independent delivery branch, which is connected in series with a fuel filter (filtration accuracy ≥5μm), a high-precision electromagnetic flowmeter (measuring range 0.3-55L / min, accuracy ±0.5%), a variable frequency gear pump (fuel supply rate adjustment range 0.5-50L / min), and a variable frequency control valve (adjustment accuracy ±0.3%), enabling independent and precise control of the flow rate of each fuel type to meet fuel supply requirements under different thrust demands.

[0039] Secondary blending tank: Equipped with two parallel blending units, each unit has a built-in spiral static mixer (mixing uniformity variance ≤5%). The tertiary tank supplies fuel to the secondary tank via independent pipelines, which are equipped with pressure sensors (measuring range 0.1~10MPa) and temperature sensors (-55℃~+45℃). The secondary tank adopts a "working-standby" switching mode: when one tank supplies fuel to the engine, the other tank completes the target component blending based on the predicted operating conditions, with a switching response time ≤0.3 seconds, avoiding fuel supply interruption.

[0040] Primary blending tank: Equipped with one main blending unit, the output lines of both secondary tanks are connected to this unit. It features built-in multi-layer baffles and an ultrasonic oscillation device (oscillation frequency 20~40kHz) to achieve deep homogenization of multi-component fuels. Both primary and secondary tanks are equipped with independent fuel supply outlets, connected to the engine's main fuel line via a three-way solenoid valve. Direct fuel supply or compound blending fuel supply mode can be selected according to the complexity of operating conditions.

[0041] Auxiliary control components: A new nitrogen purging branch is added, connecting to the three-stage fuel tank and each stage of the delivery pipeline. The nitrogen source uses an onboard small high-pressure nitrogen cylinder (pressure ≥10MPa) to purge residual fuel in the pipeline before flight or during fuel switching, preventing cross-contamination between different fuels from affecting the blending ratio. One-way valves are installed at the connections of the primary and secondary fuel tanks and the engine fuel main to prevent fuel backflow and ensure fuel supply safety in airborne environments. The filtration, high-precision flow monitoring, and nitrogen purging components can improve the blending ratio accuracy to ±0.8%, increase fuel supply rate stability by 20%, and effectively avoid fuel cross-contamination and pipeline residue effects.

[0042] For example, the parameters for the third-stage feedstock tank can be: 500 L for HEFA-SAF (Hydroprocessed Esters and Fatty Acids-Sustainable Aviation Fuel), 300 L for e-SAF, 400 L for methanol-to-jet fuel, and 600 L for conventional Jet A-1 fuel, made of aerospace-grade aluminum alloy, and equipped with explosion-proof valves and level sensors; the parameters for the second-stage blending tank can be: 200 L for each tank, with a built-in DN50 spiral static mixer and a ZCF-20 electromagnetic flow control valve; the parameters for the first-stage blending tank can be: 300 L for each tank, with an ultrasonic oscillation device of 500 W power and a working frequency of 30 kHz; the sensor group can be an OPC-N3 optical particle counter, an SHT30 temperature and humidity sensor, and a BMP388 barometric pressure sensor; the control module can use an FPGA (Field-Programmable Gate Array) core controller, integrating GT-power... The lightweight simulation algorithm has a computational latency of ≤100 ms. It supports multiple SAF technology routes such as HEFA and e-SAF, and is seamlessly compatible with existing aero-engine fuel systems. No engine modification is required, resulting in low cost for widespread application.

[0043] Specifically, Figure 2 This is a schematic flowchart of a method for blending multi-component sustainable aviation fuel on an aircraft, provided in an embodiment of this application.

[0044] like Figure 2 As shown, the method for blending multi-component sustainable aviation fuel onboard this aircraft includes the following steps: In step S201, at least one input parameter of the aircraft is collected, wherein the at least one input parameter includes at least one of the aircraft's flight phase parameters, engine thrust requirements, and environmental parameters, wherein the at least one input parameter is collected in real time by the aircraft's onboard sensor array.

[0045] It is understood that at least one input parameter in the embodiments of this application may include, but is not limited to, flight phase parameters, engine thrust requirements, and environmental parameters.

[0046] In actual implementation, the embodiments of this application can collect flight phase parameters (hovering, cruise, acceleration, takeoff, landing, taxiing), engine thrust requirements (10%~100% rated thrust), and environmental parameters (temperature -55℃~+45℃, humidity 0~100% RH, air pressure 20~101kPa) in real time. Among them, the takeoff phase focuses on monitoring low-altitude atmospheric pollution sensitive areas (altitude ≤1000m), and the cruise phase monitors the high-altitude contrail cloud formation conditions (temperature ≤-40℃, humidity ≥60%).

[0047] The embodiments of this application can collect the core input parameters of the aircraft's operating conditions and environment in real time, providing a real-time and accurate data source for subsequent calculation of the optimal mixing scheme, ensuring that the mixing scheme can match the actual state of the aircraft.

[0048] In step S202, the optimal blending scheme of the multi-component sustainable aviation fuel for the aircraft is calculated based on at least one input parameter.

[0049] It is understood that the optimal blending scheme in the embodiments of this application can be understood as a scheme obtained by analyzing the differences in emission characteristics of the engine under different operating conditions based on at least one input parameter.

[0050] In actual implementation, the embodiments of this application can use the GT-power module to perform coupled calculations on the input parameters and output the optimal blending scheme. For example, based on the real-time input parameters of the aircraft, combined with the physicochemical properties of multi-component sustainable aviation fuel and emission control targets under different operating conditions, the optimal blending scheme of multi-component fuel ratio that can balance emission reduction effect and fuel economy is calculated by the GT-power lightweight simulation algorithm.

[0051] The embodiments of this application can dynamically generate the optimal blending scheme based on input parameters, overcoming the shortcomings of fixed-ratio premixing on the ground, and enabling the fuel supply strategy to respond flexibly and scientifically to real-time changes in flight status, environment and economy.

[0052] Optionally, in one embodiment of this application, calculating the optimal blending scheme of the multi-component sustainable aviation fuel for the aircraft based on at least one input parameter includes: generating a first operating condition blending scheme in response to the input parameter being the takeoff phase or the acceleration phase, wherein the first operating condition blending scheme is to increase the blending ratio of emission-reducing fuel; generating a second operating condition blending scheme in response to the input parameter being the cruise phase, wherein the second operating condition blending scheme is to increase the blending ratio of ordinary fuel; and generating a third operating condition blending scheme in response to the input parameter being the hovering phase or the landing phase, wherein the third operating condition blending scheme is to dynamically adjust the blending ratio of emission-reducing fuel.

[0053] For example, embodiments of this application may adopt differentiated multi-component sustainable aviation fuel blending strategies according to the differences in operating conditions during different flight phases.

[0054] Specifically, during takeoff / acceleration, the aircraft operates at high thrust (thrust ≥ 70% of rated thrust) and is in a low-altitude environment, making it highly sensitive to emissions. A strategy is adopted that the e-SAF blending ratio is 30%~50%, the HEFA-SAF blending ratio is controlled at 20%~30%, and the traditional aviation kerosene blending ratio is ≤20%. Particulate matter emission intensity during takeoff is significantly higher than during cruise, reaching 3.4~3.9 times that of cruise. The high emission reduction characteristics of e-SAF and HEFA-SAF can effectively reduce PM number concentration by ≥30%, meeting the requirements for low-altitude emission control.

[0055] Once in the cruise phase, the aircraft operates at low to medium thrust (30%–50% of rated thrust) and is in a high-altitude environment. At this time, the blending strategy is adjusted to increase the proportion of conventional aviation kerosene (40%–60%), maintain the HEFA-SAF blending ratio at 20%–30%, and the e-SAF blending ratio at ≤10%. High-altitude environments are less prone to contrails and have relatively lower sensitivity to emissions. By increasing the proportion of low-cost conventional aviation kerosene, the overall fuel cost can be reduced by 10%–15%, balancing emission reduction effectiveness with economic efficiency.

[0056] During the hovering / landing phase, the aircraft exhibits variable thrust characteristics and is in a near-ground environment, requiring dynamic adjustment of the blending ratio. Specifically, the HEFA-SAF blending ratio is controlled at 25%~40%, the e-SAF blending ratio at 10%~20%, and the conventional aviation kerosene blending ratio at 30%~45%. This approach balances emission control and energy consumption requirements while adapting to the frequent operational mode switching during this phase, ensuring the synergistic achievement of flight stability and emission reduction effects.

[0057] The embodiments of this application can identify the operating conditions of the aircraft in different flight stages and generate differentiated optimal blending schemes that match each operating condition, thereby achieving precise matching of blending schemes with operating conditions and emission requirements throughout the entire flight cycle and completing emission reduction optimization throughout the entire flight cycle.

[0058] In step S203, the target fuel tank switching method and target blending ratio of the aircraft are determined based on the optimal blending scheme, so as to control the blending of the aircraft's onboard multi-component sustainable aviation fuel based on the target fuel tank switching method and target blending ratio.

[0059] It is understood that the target fuel tank switching method in the embodiments of this application can be understood as a control strategy for the fuel supply sequence and working mode of airborne fuel tanks of different components and blending tanks based on the optimal blending scheme; the target blending ratio can be understood as the multi-component fuel ratio value specified in the optimal blending scheme, and the two together constitute the execution basis for airborne fuel blending.

[0060] In practical implementation, the embodiments of this application can achieve fuel tank switching through electromagnetic valve groups according to the optimal blending scheme, with precise and rapid adjustment of the blending ratio to ensure combustion stability during operating condition switching. For example, the target blending ratio is determined based on the proportion values ​​in the optimal blending scheme, and then the target fuel tank switching method is formulated in combination with the layout of the airborne fuel tank and the fuel storage situation; the control unit sends commands to the fuel tank control valve and the flow regulating valve according to the target fuel tank switching method and the target blending ratio to achieve precise blending of multi-component fuels.

[0061] The embodiments of this application can determine the target fuel tank switching method and target blending ratio based on the optimal blending scheme, and control the blending of multi-component sustainable aviation fuel on the aircraft. It can directly execute the blending operation according to the optimal blending scheme, ensuring the accuracy of the blending ratio. At the same time, by optimizing the fuel tank switching method, the response speed of the blending process is improved, meeting the dynamic requirements of the aircraft under multiple operating conditions.

[0062] Optionally, in one embodiment of this application, controlling the blending of multi-component sustainable aviation fuel on an aircraft based on a target fuel tank switching method and a target blending ratio includes: controlling the supply of fuel from the feedstock fuel tank to the blending fuel tank based on the target blending ratio; responding to a first operating condition blending scheme, controlling the fuel supply of the first blending fuel tank based on the target fuel tank switching method, and controlling the second blending fuel tank to perform premixing; responding to a second operating condition blending scheme, controlling the fuel supply of the third blending fuel tank based on the target fuel tank switching method; and responding to a third operating condition blending scheme, controlling the fuel supply of the second blending fuel tank based on the target fuel tank switching method.

[0063] It is understood that in the embodiments of this application, the raw material oil tank can be a three-stage raw material oil tank; the blending oil tank can include a primary blending oil tank and a secondary blending oil tank; the oil supply of the first blending oil tank can be the secondary blending oil tank 1; the second blending oil tank can be the secondary blending oil tank 2; and the third blending oil tank can be the primary blending oil tank.

[0064] For example, in the embodiments of this application, the basic mixing ratio of each stage can be preset according to the flight plan, the fuel tank of the three-stage feedstock is refueled, the sensors and control modules perform self-checks, and the nitrogen purging procedure is started to remove residual oil in the pipeline for 30 seconds.

[0065] Specifically, during the takeoff phase (0-10 minutes), the ambient temperature is 25℃, the air pressure is 101kPa, the sensor detects the low-altitude environment, the GT-power simulation module outputs an e-SAF blending ratio of 40%, HEFA-SAF of 30%, and conventional aviation fuel of 30%, fuel is supplied by secondary fuel tank 1, and secondary blending fuel tank 2 is premixed and ready for use, with a fuel supply rate of 30L / min.

[0066] During the cruise phase (10~120 minutes), at an altitude of 10km, a temperature of -50℃ and an air pressure of 26kPa, the sensors detected the high-altitude environment. The simulation module adjusted the blending ratio to 50% methanol-based aviation kerosene, 25% HEFA-SAF, 20% conventional aviation kerosene, and 5% e-SAF. The system then switched to the primary blending tank for fuel supply at a rate of 15L / min. During the descent phase (120-130 minutes), the altitude decreased to 500m, the temperature was 15℃, and the emission sensor detected a rise in particulate matter concentration to 8×10⁻⁶. 5 The data is collected per cubic centimeter and fed back to the simulation module. The blending ratio is then corrected to 35% HEFA-SAF, 15% e-SAF, and 50% conventional aviation kerosene. The system is then switched to supply fuel from the secondary blending tank 2. The embodiments of this application can control the delivery of raw materials according to the target blending ratio, and match the fuel supply, premixing and switching of the target fuel tank for different working conditions, thereby adapting to the dynamic needs of multiple airborne working conditions. The direct fuel supply or compound blending fuel supply mode can be selected according to the complexity of the working conditions, taking into account the cost control during the high-altitude cruise phase and the emission reduction requirements during the low-altitude take-off phase, which is in line with the cost control goals of the large-scale commercialization of SAF.

[0067] Optionally, in one embodiment of this application, the method further includes: collecting emission data and environmental data of the aircraft; and correcting the target fuel tank switching method and target mixing ratio based on the emission data and environmental data.

[0068] It is understood that the emission data in the embodiments of this application may include at least one of particulate matter number concentration and gaseous pollutant emission data; the environmental data may include at least one of temperature, humidity and air pressure.

[0069] In practical implementation, the embodiments of this application can install an integrated emission sensor group 50 cm downstream of the aircraft's tail exhaust nozzle, including an optical particle counter (measurement range 10~1000 nm, accuracy ±5%), NO... x / CO chemical sensor (detection limit 0.1 ppm) collects particulate matter number concentration and gaseous pollutant emission data in real time, with a data sampling frequency of 10 Hz.

[0070] Furthermore, temperature and humidity sensors (measurement accuracy ±0.5℃, ±3% RH) and air pressure sensors (measurement accuracy ±0.1 kPa) are installed on the outside of the fuselage and the engine air intake to monitor flight environment parameters in real time and provide a basis for mixing ratio correction.

[0071] For example, the embodiments of this application can collect emission data and environmental data every 5 seconds through sensors, and adjust the blending ratio in real time to ensure a balance between emission compliance and economy. Through real-time sensing of temperature, humidity and pressure, it can adapt to extreme flight environments of -55℃ to +45℃ and 20 to 101 kPa, and maintain fuel mixing uniformity of more than 95%.

[0072] The embodiments of this application can collect aircraft emission data and environmental data to dynamically correct the target fuel tank switching method and mixing ratio, thereby enhancing environmental adaptability, adapting to extreme flight environments, and maintaining fuel mixing uniformity.

[0073] Optionally, in one embodiment of this application, correcting the target fuel tank switching method and target blending ratio based on emission data and environmental data includes: constructing a digital twin model of fuel blending-combustion emissions based on emission data and environmental data; and correcting the target fuel tank switching method and target blending ratio based on the digital twin model in response to emission data exceeding a preset threshold.

[0074] It is understood that the digital twin model of fuel blending-combustion emissions in the embodiments of this application can be a digital mapping model based on physical blending and combustion systems, capable of simulating fuel mixing states and combustion emission results under different blending ratios and environmental conditions; the preset threshold can be particulate matter emission concentration ≤1×10 during takeoff. 6 Units / cm³ or ≤3×10 during cruise phase 5 The preset threshold can be set by those skilled in the art according to the actual situation, and no specific restrictions are imposed here.

[0075] For example, in this application embodiment, the collected emission data and environmental data can be fed back to the simulation module (built-in GT-power) to construct a digital twin model of fuel blending and combustion emissions. When the particulate matter emission concentration exceeds a preset threshold (≤1×10⁻⁶ during takeoff), the model will be used to simulate the emissions. 6 Units / cm³, cruise phase ≤3×10 5 When the fuel volume is (units / cm³), the model uses a PID algorithm to correct the blending ratio with a correction step size of 0.5%~2% to ensure emission control accuracy. Simultaneously, considering the influence of temperature on fuel-liquid bridge force, the mixer oscillation frequency is automatically adjusted when the ambient temperature changes by ≥5℃ to prevent fuel stratification. When the pipeline flow deviation exceeds ±1%, the variable frequency gear pump speed is adjusted in real time to calibrate the fuel supply rate.

[0076] The embodiments of this application can construct a digital twin model of fuel blending and combustion emissions, and correct the target fuel tank switching method and target blending ratio when emission data exceeds the standard. Thus, based on the closed-loop control system of environmental perception and digital twin, the target fuel tank switching method and blending ratio can be accurately adjusted, improving adaptability to extreme environments and avoiding the problem of stratification and deposition caused by temperature changes.

[0077] Specifically, it can be combined with Figure 3 As shown, the working principle of the airborne multi-component sustainable aviation fuel blending method in this application is explained in detail with a specific embodiment.

[0078] like Figure 3 As shown, the embodiments of this application may include environmental / operating condition / fuel status input → GT-power simulation → blending execution → emission detection → feedback correction.

[0079] Specifically, this embodiment of the application uses real-time collected route planning settings, environmental parameters, flight operating condition parameters, and fuel status parameters as input. These environmental / operating condition / fuel status input parameters are sent to a simulation module, which serves as the core computing unit. This module integrates an FPGA core controller and the GT-power lightweight simulation algorithm to dynamically generate the optimal blending scheme and match differentiated blending strategies for different flight phases. After the calculation results are sent to the blending execution layer, the system will connect to the three-stage feedstock tanks storing various fuels, switching between the secondary and primary blending tanks. By controlling pumps, valves, and other actuators, it precisely completes the proportioning and mixing of different fuel components and supplies blended fuel adapted to the current operating conditions to the engine, achieving fuel supply strategy adaptation for takeoff, cruise, and landing phases.

[0080] Emissions generated during engine operation enter the emission detection layer, where particulate matter and gaseous matter are detected to collect emission data. This data is then transmitted to the algorithm correction module, which, in conjunction with environmental parameters and relying on the fuel blending-combustion emission digital twin model, generates blending ratio correction and fuel injection rate calibration commands. These commands are then fed back to the blending execution layer, forming a complete closed-loop control process.

[0081] The airborne multi-component sustainable aviation fuel blending method proposed in this application can calculate the optimal blending scheme of the airborne multi-component sustainable aviation fuel based on the aircraft's input parameters, and implement blending control by combining the target fuel tank switching method and blending ratio, thereby achieving precise control of fuel supply rate and blending ratio. For flight scenarios with multiple operating conditions and drastic changes in temperature, humidity, and pressure, a blending combustion method covering all flight conditions is established to balance emission reduction requirements and fuel costs at different stages, achieving synergistic optimization of emission reduction and economy. This solves the problems in related technologies, such as the inability to adapt to the dynamic requirements of multiple airborne operating conditions and the lack of a real-time temperature, humidity, and pressure control mechanism, resulting in insufficient flexible multi-component blending capability and environmental adaptability; the inability to achieve full-flight cycle emission reduction optimization due to the lack of a dynamic correlation model of "operating condition-blending ratio-emission"; the contradiction between emission reduction and economy; and the lack of a real-time emission data feedback and correction mechanism.

[0097] Optionally, in one embodiment of this application, the mixing module 300 includes: a conveying unit, a first control unit, a second control unit, and a third control unit.

[0098] The conveying unit is used to control the delivery of fuel from the feedstock tank to the blending tank based on the target blending ratio.

[0099] The first control unit is used to respond to the first working condition mixing scheme, control the oil supply of the first mixing tank based on the target oil tank switching mode, and control the second mixing tank to perform premixing.
