Experimental Elastic Deformation Characterization of a Flapping-Wing MAV using Visual Image Correlation

摘要: *† This paper presents a method for using visual image correlation (VIC) data to decouple the rigid-body-motion of flexible wing from elastic deformation. Estimating deformation can be used gain insight into unsteady aerodynamics associated with flapping flight. By making use dynamic VIC system, which measures full-field displacements, entire motion measured. If experiment is setup carefully, combination rigid-bodymotion and due flexibility measured simultaneously single specimen. Discussed in this determining homogeneous transformation matrix (HTM) rigid-body-motion. The HTM project rigid body portions wing, thereby, separating total displacement. A series static tests involving known rotations deformations were carried out test method. Following validation, was applied two different flexible, wings contours successfully generated.
