柔性变体飞行器梳齿形翼肋结构的设计与仿真
Design and Simulation of Comb Wing Rib Structure of Flexible Variant Aircraft
摘要
Abstract
The integrated aircraft needs to meet the wide speed range,complex and changeable mission environment,and the traditional fixed-wing aircraft can not meet many flight requirements.In view of this situation,a comb wing rib structure was designed to actively change the shape of the wing by controlling the deformation of the wing rib driven by intelligent materials,which can improve the aerodynamic perfor-mance of the aircraft,and adapt to the task environment of the intelligent deformation UAV.Based on Ansys Workbench,the static analysis of the wing rib structure was carried out and the dynamic deforma-tion process of the chord bending was simulated.The deformation angle of the front and back edges of the wing rib structure was taken as the key optimization objective to optimize the structure parameters of the wing rib,so as to obtain the best combination of structural parameters of the wing rib.The experimental results show that the optimized wing fin structure can achieve a leading edge deflection of 10.75° and a trailing edge deflection of 10.75° on the premise of meeting the yield strength requirements.This deforma-tion not only improves the lift-drag ratio of the aircraft,but also effectively improves the aerodynamic per-formance of the aircraft under subsonic conditions.The comb wing rib structure driven by intelligent mate-rials proposed in this paper can realize the stable deformation of the front and rear edges,enhance the climbing ability of the aircraft,and reduce fuel consumption,and provide more flexible and efficient flight control performance.This paper uses the method of simulation experiment,and the results have some errors with the reality.We can use the actual wind tunnel experiment in the future.关键词
