Problems solved by technology
The amount of fuel calculated according to this method is not in good agreement with the weight measured by the fuel test after the aircraft is manufactured, and it is prone to large deviations, which seriously affects the design of the entire aircraft, and is no longer suitable for the current technological development level and model development requirements.
Through the research on domestic and foreign documents related to the quality characteristics of airborne fuel oil, it is found that there is no complete and standardized calculation process

Description
technical field [0001] The invention relates to the weight direction research technology in the field of overall aircraft design, in particular to a method for processing the weight of aircraft fuel. Background technique [0002] Fuel weight occupies an important proportion in the total weight of an aircraft, and fuel consumption is one of the main factors that cause changes in aircraft mass characteristics during flight. Fuel has fluidity, and its quality characteristics are obviously affected by flight attitude and overload, especially when the aircraft is in the take-off and landing stages. In order to ensure flight safety, it is necessary to give accurate fuel and aircraft center of gravity data. [0003] The internal space occupied by real fuel is relatively complex, mainly formed by the body structure, fuel system and other structural parts, finished parts, cables, etc.; the real fuel level has tilts and oscillations, and the description of the fuel level is complex, ...
