Research On Fuel Consumption Of General Trainer Based On Training Task

In recent years,in the context of the rapid development of China’s aviation industry,not only has civil aviation achieved rapid development,but China’s general aviation has also developed rapidly.Aiming at the current situation of less research on general aviation in China at this stage,the fuel consumption of general trainer was studied in this paper.Based on the introduction of training subjects and training tasks in private training,instrument license training,business license single training,business license multiple training and airline transportation license training in the training outline,the flight training tasks are analyzed.According to the characteristics of the flight training mission,in order to facilitate the analysis of the fuel consumption of the general trainer,the flight training mission is divided into a complex phase consisting of the takeoff and landing course phase and a maneuver training phase,and a non-composition consisting of the takeoff climb phase,the cruise phase,and the landing and landing phase Complex stages.The learning curve model is introduced and applied to the fuel consumption research of general trainer.Taking the learning rate as one of the influencing factors of fuel consumption,the gray influencing factor analysis was used to obtain the main influencing factors of fuel consumption.The fuel consumption model of general trainer in complex stages was established by support vector machine regression.The grid search method,genetic algorithm,and particle swarm algorithm were used to optimize the parameters and compare them to obtain a fuel stage model with high accuracy in the complex stages of training tasks.A formula model was established for the non-complicated stages of the training task,and simulation was carried out using Monte Carlo method to verify its feasibility.This paper provides a new idea and method for estimating the fuel consumption of the single flight training mission of general trainer by establishing fuel consumption models of the general trainer training mission at different stages.
