Modeling method for fuel consumption model of fixed-wing aircraft

Abstract

The invention discloses a modeling method for a fuel consumption model of a fixed-wing aircraft. The modeling method comprises the following steps: acquiring fuel consumption data; establishing a relationship between the flight height and the flight speed; establishing a relationship between the flight height and the oil consumption rate; calculating the flying speeds of the aircraft in different accelerator states; calculating the oil consumption rate of the aircraft flying in different accelerator states under different load conditions; calculating the current load capacity and the oil consumption rate of flight at different accelerator states at the current flight height; and calculating the current oil consumption rate according to the current flight speed. According to the technical scheme, the data size needed by model calculation is far smaller than that of an accurate fuel consumption model, the data needed by the model is easier to obtain compared with that needed by the accurate fuel consumption model, the model calculation amount is far smaller than that of the accurate fuel consumption model, and the simulation operation efficiency is improved.

AI Technical Summary

Problems solved by technology

Establishing an accurate fuel consumption model requires establishing an aircraft aerodynamic model and obtaining engine curves, and these data are usually used as the core data of aircraft and engines, which are strictly controlled by various equipment development units and cannot be obtained by ordinary personnel

At the same time, the calculation of an accurate fuel consumption model consumes a lot of resources, but in task-level simulation, the modeling of the simulation model does not need to be so detailed, and the establishment of an accurate fuel consumption model is a waste of computing resources.
