Design and Validation of Chute Lugs on Variable Camber Wing Trailing Edge
摘要
Abstract
Currently,the variable camber wings on civil aircraft are mainly morphed by mechanical drive.When the trailing edge of the variable camber wing morphs,there will be the change of the relative position relationship between the wing skin and the drive rod of the drive mechanism.This often leads to discordant deformation between the driving mechanism and the skin.To meet the morph design requirements of variable camber wing trailing edge,this paper proposed a design scheme of connecting structure between drive mechanism and skin to realize deformation coordination of the trailing edge.By establishing the motion model of the driving mechanism on the variable camber wing trailing edge,the motion characteristics of the mechanism points,the connection points between the driving mechanism and the skin during deflection of the trailing edge were analyzed,and the relative position relationship between the mechanism points and the skin was obtained.Then,the grooving form and method of lugs on skin were studied,and the design of chute lugs was carried on.Finally,the deformation and bearing capacity of the variable camber wing trailing edge prototype were tested,and the results showed that the chute lugs design scheme of the variable camber wing trailing edge can meet the requirements of aerodynamic shape and bearing capacity during bending of wing.关键词
