Aircraft fuel consumption calculation system

Abstract

The invention relates to an aircraft fuel consumption calculation system which comprises a database data storage module suitable for obtaining data information and storing the data information into adatabase, a flight operation division module suitable for dividing the flight operation into two stages including an LTO stage and a CCD stage according to flight time information and height information of an ADS-B flight path recording point, a fuel flow determination module suitable for determining the fuel flow of each stage according to the data information, an LTO stage fuel consumption calculation module suitable for calculating LTO stage fuel consumption according to the fuel flow in the LTO stage, a CCD stage fuel consumption calculation module suitable for calculating CCD stage fuel consumption according to the fuel flow in the CCD stage, and a flight operation fuel consumption calculation module suitable for calculating the fuel consumption TF of the whole operation process of the flight according to the fuel flow in the LTO stage and the fuel flow in the CCD stage. The total oil consumption of the complete operation process of the flight can be calculated, and the oil consumption in each stage can be calculated according to stage division so as to meet the requirements of stage analysis and statistics.

Description

technical field [0001] The invention relates to the field of aircraft operating state identification and performance analysis, in particular to an aircraft fuel consumption calculation system. Background technique [0002] Air transport has become one of the most convenient modes of transportation, but its flight has a serious impact on the environment. Therefore, energy saving and emission reduction in aviation operation has become an important part of promoting the development of green civil aviation. At the same time, reducing aircraft emissions also means reducing fuel consumption, which is crucial for airlines to reduce operating costs. In addition, due to the consideration of commercial secrets, airlines will not provide data such as flight load and fuel consumption to the outside world. Therefore, a fuel consumption estimation method is required before analyzing and counting flight fuel consumption. [0003] In the prior art, the fuel consumption estimation method m...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the fuel consumption estimation method mainly has the following limitations: the simulation model assumes that the aircraft is flying according to the ideal track, but there is a certain gap between the actual flight track of the aircraft and the ideal track; the LTO method is only applicable to 3000 meters above the airport. The calculation of fuel consumption within the range of feet is not applicable to en-route flights above 3000 feet; the accuracy of neural network method estimation depends on the scope of the learning library, so a complete and large learning library needs to be established to obtain the best results
