Description

<p>Morphing technologies are attracting much attention as breakthrough technologies to improve the performance of aircrafts. Structural designing of morphing wings is one of the important challenges and corrugated panels are regarded as promising candidate materials for morphing wings. In this paper, designs of corrugated morphing wings for drag reduction are studied considering necessary actuation forces. Static aeroelastic models are constructed to assess the aerodynamic performances or deformations of morphing wings, and aeroelastic analyses are performed with multiple parameter settings. An objective function considering the drag coefficient and the necessary actuation force is prepared and the performance of each case is analyzed. Numerical results show that there is a desirable design parameter or actuation when the two evaluation components are considered at the same time.</p>
