Investigation of modal strain energy for varying ribs orientation concept of untapered wing box model

The variable ribs' orientation concept is becoming one of the promising options for innovative wing box design for aircraft whereby several previous studies have shown that significant improvement in aeroelastic characteristics can be acquired without any increment in weight. This paper present...
