考虑气动弹性影响的机翼气动外形设计研究

采用三维Euler方程为控制方程,耦合静气动弹性平衡方程,进行机翼静气动弹性数值模拟;在机翼静气动弹性分析的基础上,结合Takanashi余量修正方法对三维大展弦比机翼进行气动外形反设计,以确定机翼的型架外形.以某型支线飞机的大展弦比机翼为算例,进行了静气动弹性数值模拟和机翼型架外形设计研究,设计结果表明发展的机翼静气动弹性数值模拟和型架外形设计方法是合理可行的.

Study on Aerodynamic and Aeroelastic Integrated Design Method for Wing

In the study,the aerodynamic analysis of wing is achieved by solving 3D unstructured Euler equations,which integrated static aeroelastic effect.Then,the Jig-shape design method of wing is presented,the method based on the modified Residual-Correction approach of Takanashi coupled with aeroelastic effect analysis.The serve to validate the current design method by application to a high aspect ratio transonic wing of a branch airline.The result of computation show that the method developed in the study is corr...
