Embodiment Construction

[0074] The technical solutions and beneficial effects of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0075] 1 Overview

[0076] Aiming at the impact of mass change on fuel consumption that is not considered in the cruise phase fuel consumption model in the BADA database, this paper proposes a fuel consumption prediction model under the influence of crosswinds and aircraft weight changes during the cruise phase. At the same time, considering that the impact of wind on fuel mileage has not been considered in the model performance manual and the influence of aircraft quality changing at any time, we have used the above fuel consumption prediction model to analyze the impact of different Mach numbers and different flight altitudes on fuel mileage ( SR) to find the maximum range Mach number and optimal cruising altitude corresponding to different flight qualities during the entire cruising phase of flight. Finally, by us...

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,...
