[0045] Figure 2 It is a schematic diagram of the system architecture of a carbon emission comparison system for new and old aircraft models proposed by the present invention. Detailed Embodiments
[0046] Referring to Figure 1 and Figure 2 , a carbon emission comparison method for new and old aircraft models proposed by the present invention includes the following steps:
[0047] S1. Obtain the corresponding times of the first aircraft type and the second aircraft type in the LTO phase of the same flight route.
[0048] S2. Query the fuel consumption data corresponding to the first aircraft type and the second aircraft type in the LTO phase of the flight from the fuel quantity query system.
[0049] S3. Calculate the carbon emissions of the first aircraft type and the second aircraft type in the LTO phase based on the corresponding times and fuel consumption data of the first aircraft type and the second aircraft type in the LTO phase of the flight.
[0050] In this embodiment, the LTO phase of the flight includes the push - back phase, take - off phase, climb phase, landing phase, and taxi - in phase of the flight; step S3 specifically includes: obtaining the fuel consumption ratio of each phase in the LTO phase of the flight for the first aircraft type and the second aircraft type respectively; obtaining the engine fuel efficiency of each phase in the LTO phase of the flight from the fuel consumption data for the first aircraft type and the second aircraft type respectively; calculating the carbon emissions in the LTO phase for the first aircraft type and the second aircraft type respectively according to the fuel consumption ratio, engine fuel efficiency, and corresponding time of each phase in the LTO phase of the flight.
[0051] In this embodiment, calculating the carbon emissions in the LTO phase according to the fuel consumption ratio, engine fuel efficiency, and corresponding time of each phase in the LTO phase of the flight is specifically as follows:
[0052] C1 = η1×t1×e1 + η2×t2×e2 + η3×t3×e3 + η4×t4×e4 + η5×t5×e5;
[0053] Where, η1 is the fuel consumption ratio in the push - back phase; η2 is the fuel consumption ratio in the take - off phase; η3 is the fuel consumption ratio in the climb phase; η4 is the fuel consumption ratio in the landing phase; η5 is the fuel consumption ratio in the taxi - in phase; e1 is the engine fuel efficiency in the push - back phase; e2 is the engine fuel efficiency in the take - off phase; e3 is the engine fuel efficiency in the climb phase; e4 is the engine fuel efficiency in the landing phase; e5 is the engine fuel efficiency in the taxi - in phase; t1 is the time in the push - back phase; t2 is the time in the take - off phase; t3 is the time in the climb phase; t4 is the time in the landing phase; t5 is the time in the taxi - in phase; C1 is the carbon emissions in the LTO phase.
[0054] In this embodiment, the carbon emissions of LTO = the product of the time spent in each stage and the fuel efficiency, and different fuel consumption ratios are given for each stage. The ratio setting is mainly summarized based on the power principle of the aircraft and a large amount of actual flight data. The ratio in the taxi-out stage is 7%, because in the taxi-out stage, the aircraft mainly relies on its own inertial power, mainly to provide enough thrust to overcome the ground friction and the inertia of the aircraft, so that the aircraft can smoothly taxi from the apron to the runway. The fuel consumption is small, and usually a lower engine power is used. The ratio in the takeoff stage is 100%, because in the takeoff stage, the maximum thrust is required to overcome gravity and air resistance, so the engine power needs to be adjusted to 100%. The ratio in the climb stage is 85%, because in the climb stage, the aircraft needs to continuously increase its altitude, the engine power is high, and the fuel consumption is large. The fuel consumption in the landing stage is 30%. In the landing stage, considering the gravity of the aircraft itself, the fuel consumption is less. The fuel consumption rate in the taxi-in stage is 7%. The principle in the taxi-in stage is similar to that in the taxi-out stage, and the engine power is low, mainly used to control the speed and attitude of the aircraft. Generally speaking, the carbon emissions in the LTO stage = taxi-out time * 7% engine fuel efficiency + takeoff stage * 100% engine fuel efficiency + climb stage * 85% engine fuel efficiency + landing stage * 30% engine fuel efficiency + taxi-in duration * 7% engine fuel efficiency. The fuel consumption ratios in each stage of different aircraft models are the same. This ratio has been tested by a large amount of actual data and has universality.
[0055] S4. Calculate the carbon emissions of the first aircraft model and the second aircraft model in the CCD stage respectively.
[0056] In this embodiment, step S4 specifically includes:
[0057] Obtain the flight nautical miles and fuel quantity information fuel corresponding to the first aircraft model and the second aircraft model respectively;

[0060] Calculate the carbon emissions of the first aircraft model and the second aircraft model in the CCD stage respectively according to the fuel quantity information fuel, load factor load, transport factor freight, cabin class information and seat information seats corresponding to the first aircraft model and the second aircraft model.
[0061] In this embodiment, the cabin class information includes, but is not limited to, the first cabin class and the second cabin class; the carbon emissions of the first aircraft type and the second aircraft type in the CCD stage are calculated according to the fuel quantity information fuel, load factor load, transport factor freight, cabin class information, and seat information seats of the first aircraft type and the second aircraft type, specifically including:
[0062] Calculate the carbon emissions of the first cabin class in the CCD stage according to the flight nautical miles, fuel quantity information fuel, load factor load, transport factor freight, cabin class information, and seat information seats;
[0063] Obtain the seat ratio between the second cabin class and the first cabin class, and calculate the carbon emissions of the second cabin class in the CCD stage according to the carbon emissions of the first cabin class in the CCD stage and the seat ratio;
[0064] Sum the carbon emissions of the first cabin class in the CCD stage and the carbon emissions of the second cabin class in the CCD stage to obtain the total carbon emissions in the CCD stage.
[0065] In this embodiment, calculating the carbon emissions of the first cabin class in the CCD stage according to the flight nautical miles, fuel quantity information fuel, load factor load, transport factor freight, cabin class information, and seat information seats specifically includes:
[0066] Calculate the carbon emissions per seat corresponding to the first cabin class;
[0067] Calculate the carbon emissions of the first cabin class in the CCD stage according to the carbon emissions per seat;
[0068] The calculation process of the carbon emissions per seat is as follows:
[0069] C x =(fuel * freight) / (seats * load);
[0070] where C x is the carbon emissions per seat; fuel is the fuel quantity information; freight is the transport factor; load is the load factor; seats is the seat information.
[0071] In this embodiment, obtaining the seat ratio between the second cabin class and the first cabin class, and calculating the carbon emissions of the second cabin class in the CCD stage according to the carbon emissions of the first cabin class in the CCD stage and the seat ratio specifically includes:
[0072] The carbon emissions of the second cabin class in the CCD stage = the carbon emissions of the first cabin class in the CCD stage * the seat ratio.
[0073] S5. Determine the carbon emission growth rate of the first model relative to the second model based on the carbon emissions of the first model and the second model in the LTO stage and the carbon emissions in the CCD stage.
[0074] In this embodiment, step S5 specifically includes:
[0075] Calculate the total carbon emissions corresponding to the first model and the second model respectively according to the carbon emissions of the first model and the second model in the LTO stage and the carbon emissions in the CCD stage;
[0076] Calculate the carbon emission growth rate of the first model relative to the second model according to the total carbon emissions corresponding to the first model and the second model.
[0077] In this embodiment, based on flight data, by calculating the carbon emissions of the pushback, takeoff, climb, landing, taxi-in and cruise stages of flights of new and old models on the same route, a differential percentage calculation is made for the carbon emission difference between the new and old models. This helps airlines and aircraft leasing companies optimize the fleet composition on the route, and based on the low-carbon and green flight concept, actively upgrade the fleet structure and increase the proportion of low-carbon aircraft.
[0078] For two models, A320 and A320NEO, the flight numbers are CA4538 and CZ5626 respectively. The first model is A320NEO and the second model is A320. The time spent by A320 in the LTO stage is as follows:
[0079] Phase Description Duration Taxi out The flight taxied out from the boarding gate at 22:55 6min Takeoff After taxiing out, the flight prepared on the runway and took off at 23:01 1min Climb The climb started at 23:02 after takeoff and was completed at 23:11 9min Landing The flight began to descend at 23:49 and landed smoothly at 23:59 10min Taxi in After landing, the flight taxied in to the arrival boarding gate at 00:54 5min
[0080] Through the fuel quantity query system, the fuel consumption of A320 is obtained as 7,571 kg / h, that is, 126.18 kg / min. Therefore, the carbon emissions of the A320 model in the LTO stage can be obtained
[0081] C1 = 6 * 7% * 126.18 + 1 * 100% * 126.18 + 9 * 85% * 126.18 + 10 * 30% * 126.18 + 5 * 7% * 126.18
[0082] = 1567.156 kg;
[0083] The time spent by A320NEO in the LTO stage is as follows:
[0084] Phase Description Duration Taxi out The flight taxied out from the boarding gate at 20:25 9min Takeoff After taxiing out, the flight prepared on the runway and took off at around 20:34 1min Climb The climb started at 20:35 after takeoff and was completed at 20:44 9min Landing The flight began to descend at 22:20 and landed smoothly at 22:30 10min Taxi in After landing, the flight taxied in to the arrival boarding gate at 22:36 6min
[0085] Through the fuel quantity query system, the fuel consumption of A320 is obtained as 6,057 kg / h, that is, 100.95 kg / min. Therefore, the carbon emissions of the A320NEO model in the LTO stage are as follows:
[0086] C1 = 9 * 7% * 100.95 + 1 * 100% * 100.95 + 9 * 85% * 100.95 + 10 * 30% * 100.95 + 6 * 7% * 100.95
[0087] = 1282.065 kg.
[0088] In this embodiment, through the flight dynamic system, the flight nautical miles of the flight are obtained, and the fuel quantity information fuel of the aircraft type is obtained from the aircraft type nautical mile fuel quantity query table. Through the load factor and transport coefficient query system, the load factor load and transport coefficient freight of the aircraft type are queried using the aircraft type and nautical miles of the flight. Through the aviation information black screen, the class information and corresponding seat information seats of the flight are obtained. The carbon emissions in the CCD stage of the first class of the flight are calculated.
[0089] Carbon emissions per single seat in the first class = (fuel * freight) / (seats * load) = (fuel quantity * transport coefficient) / (number of seats * load factor).
[0090] Carbon emissions in the second class = Carbon emissions in the first class * seat ratio. For the two aircraft types A320 and A320NEO, with flight numbers CA4538 and CZ5626 respectively, the data related to the aircraft types are as follows:
[0091] Flight number CA4538 CZ5626 Aircraft number B6828 B32EV Aircraft type A320 A320NEO Flight distance 1308 nautical miles 1308 nautical miles Fuel quantity 5924.88 kg 5034.59 kg Load factor 0.756 0.756 Transport coefficient 0.7999 0.7999 Seat layout J8Y150 J4Y162 Number of seats in the first class 150 162 Carbon emission per seat in the first class 41.79 kg 32.88 kg Total carbon emission in the first class 6268.5 kg 5326.56 kg Total carbon emission in the second class 6268.5 kg 5326.56 kg Overall carbon emission 12537 kg 10653.12 kg
[0092] Through the aircraft type nautical mile fuel quantity query table, the load factor and transport coefficient query system, and the aviation information black screen, it can be obtained that
[0093] Carbon emissions per single seat in the first class of the A320 aircraft type in the CCD stage
[0094] = (fuel * freight) / (seats * load) = (5924.88 * 0.7999) / (150 * 0.756) = 41.79 kg;
[0095] Carbon emissions in the first class = Carbon emissions per single seat in the first class * number of seats in the first class = 41.79 * 150 = 6268.5 kg
[0096] Carbon emissions in the second class = Carbon emissions in the first class / ratio = 6268.5 / 1 = 6268.5 kg;
[0097] Total carbon emissions of the A320 aircraft type = 41.79 * 150 + 6268.5 / 1 = 12537 kg;
[0098] Carbon emissions per single seat in the first class of the A321NEO aircraft type in the CCD stage
[0099] =(fuel * freight) / (seats * load) * seats = (5034.59 * 0.7999) / (162 * 0.756) = 32.88 kg;
[0100] Carbon emissions of the first class = Carbon emissions per seat in the first class * Number of seats in the first class = 32.88 * 162 = 5326.56 kg;
[0101] Carbon emissions of the second class = Carbon emissions of the first class / Ratio = 5326.56 / 1 = 5326.56 kg; The overall carbon emissions of the A321NEO model = 32.88 * 162 + 5326.56 / 1 = 10653.12 kg;
[0102] The carbon emissions of A320 and A320NEO are as follows:
[0103] Aircraft type A320 A320NEO Flight distance 1308 nautical miles 1308 nautical miles Carbon emission in the LTO phase 1567.156 kg 1282.065 kg Carbon emission in the CCD phase 12537 kg 10653.12 kg Total carbon emission per kilometer 14104.16 kg 11935.19 kg Total number of seats 158 166 Carbon emission per seat-kilometer 0.068 kg 0.056 kg
