A wing that can be deformed the geometrical shape seamlessly and continuously to improve aerodynamic performance of wing is called a morphing wing. A compliant mechanism has been proposed as the internal structure of the wing to achieve the desirable deformation. Most previous studies have adopted the ground structure approach to obtain the internal structural configuration of the morphing devices. We consider to adopt the level set-based topology optimization method to improve the structural feature of the morphing wing. Then, we begin with the problem formulation to minimize the difference between the ideal given deformed shape and the deformation of the obtained compliant configuration. This manuscript gives current status of the study by illustrating some simple numerical examples.
