Abstract
The compromise of multi-objective optimization design on aircraft performance can no longer meet people's growing needs,and designing aircraft with more comprehensive performance is the inevitable development trend of future aircraft design.Aiming at the aerodynamic optimization of a UAV wing,the comprehensive design of wing surface shape,airfoil and trailing edge bending was studied.CST method was used to parameterize the airfoil,and the trailing edge deformation mode was determined based on the characteristics of knuckle-bending structure.The root tip ratio,wing area and trailing edge bending were parameterized by Catia secondary development method.The agent optimization algorithm of ARI_XunZhu optimization platform was used to optimize the design,and finally two groups of bending wing configurations were obtained.The results show that the wing configuration with good performance can be obtained by integrating the bending design into the whole wing design process.The performance of the two wings with different lift coefficient is better than that of the initial model.The performance of the two wings is crossed,which is suitable for high and low lift conditions respectively.The bending of the trailing edge of the wing has a certain regularity,and with the increase of the lift coefficient,the bending angle and bending area also increase.关键词
