Method for predicting fuel consumption of aircraft

Abstract

The invention provides a method for predicting fuel consumption of an aircraft, which comprises the following steps of: dividing the whole flight process into 22 flight segments according to waypoints of each flight, a takeoff and landing airport and a flight plan; using a correlation analysis method to extract parameters with high correlation with flight fuel consumption as input; performing regression prediction on flight fuel consumption of each leg through a random forest algorithm, and determining important parameters of the random forest algorithm by using a grid search method; the final predicted value is the sum of the predicted values of the sub-legs, and evaluating the model through the predicted value. The accuracy of the method is improved compared with the oil calculation accuracy of an existing flight planning system (FPS) in the industry, the purposes of improving the aviation oil use efficiency, improving the economic benefits of airlines and reducing the overall oil consumption level of the industry can be achieved, a theoretical reference is provided for an airline company to make a fuel oil decision, and a contribution is made for achieving the dual-carbon target of the civil aviation industry.

Description

technical field [0001] The invention belongs to the technical field of machine learning, and in particular relates to a method for predicting aircraft fuel consumption. Background technique [0002] The current aircraft fuel consumption calculation method is based on the flight planning system (FPS) of the airline company based on the weather report and upper-altitude wind temperature data of the day, the dispatcher manually selects the route and aircraft type, the flight load data and the selected aircraft performance data , automatically calculate the fuel consumption during the flight, and moderately increase the fuel according to various flight operation specifications and flight regulations, and the final flight carry-on fuel is the sum of the calculated fuel consumption and the moderately increased fuel. Although this method is safe, excess fuel often occurs, and even fuel consumption increases due to excess fuel, which increases the weight of the aircraft, reducing th...

Problems solved by technology

Although this method is safe, it often leads to excess fuel, and even the phenomenon of increased fuel consumption due to the increase of aircraft weight due to excess fuel, which reduces the efficiency of aviation fuel use.
