弹性效应对Z形折叠翼气动特性的影响
Influence of elastic effect on aerodynamic characteristics of Z-Shaped folding wing
摘要
Abstract
To accurately capture the aerodynamic characteristics of Z-shaped folding wing at different folding angles,while considering the influence of the structural elastic effect of different wing segments,a parametric aerodynamic-structural coupling model was constructed based on a quasi-steady state environment.Using ANSYS Workbench software with the RNG k-ε turbulence model and the Coupled algorithm,numerical simulation was conducted to analyze the aerodynamic characteristics of the folding wing under the action of elastic effect and the results were compared with those of a rigid wing.Additionally,the deformation laws of the elastic folding wing in different flight environments were systematically explored.The results show that under the influence of elastic effect,the absolute values of lift and pitching moment of the folding wing are slightly lower than those of the rigid wing.As the folding angle increases,the impact of elastic deformation on the overall aerodynamic performance of the wing stabilizes.When the folding angle is 90°,the differences in lift and pitching moment between the elastic and rigid wings are only 0.93%and 0.70%respectively.Furthermore,under the influence of elastic effect,the maximum deformation of the wing occurs at the wingtip.As the folding angle increases,the magnitude of wingtip deformation gradually decreases.关键词
