Cruise stage fuel consumption prediction method for aircraft mass change

Abstract

The invention discloses a cruise stage fuel consumption prediction method for aircraft mass change. The method comprises the following steps: step 1, considering the influence of mass change and crosswind, and constructing a cruise stage fuel consumption model; step 2, aiming at the model constructed in the step 1, establishing an objective function and constraint conditions; and step 3, solving the optimal solution of the objective function to obtain the optimal fuel mileage under each mass and the corresponding optimal cruise height and maximum cruise Mach number. According to the prediction method, a cruise fuel consumption prediction model based on aircraft mass change can be established, and the optimal cruise height and the optimal cruise speed corresponding to the maximum fuel mileage of different aircraft masses are determined through optimization calculation by the model.

Description

technical field [0001] The invention relates to a method for predicting fuel consumption in the cruising stage of aircraft quality changes. Background technique [0002] With the rapid development of air transport, it is predicted that in the next 15 years, air traffic volume will double [1]. The rise of fuel prices and the restrictions of environmental policies have determined that the issue of saving fuel consumption by aircraft has become a hot issue that air traffic control and dispatch managers and researchers pay attention to. According to the report of the International Air Transport Association (IATA) [2], the fuel cost of the aircraft has accounted for more than 35% of the operating costs of the airlines, and it has risen to the first place in the main business costs of the airlines. The benefit space of airlines, airlines are facing enormous pressure to survive. Both IATA[2] and ICAO[3] have proposed long-term goals to improve flight fuel efficiency. At present,...

Problems solved by technology

Assaad et al.[20] reduced fuel consumption by optimizing air traffic flow considering the influence of crosswinds, but only considered the influence of tailwinds, ignoring headwinds, which is not suitable for practical applications, and did not add crosswinds to the fuel consumption model. calculate

[0007] To sum up, at present, most researches on fuel consumption prediction during aircraft cruise do not take performance parameters, crosswind and aircraft mass changes into consideration in the fuel consumption prediction model, resulting in There are certain errors in the forecast results
