A low-dimensional tool for flow-structure interaction problems based on proper orthogonal decomposition (POD) and modified linear stochastic estimation (mLSE) was analyzed. It was found that the method utilized the dynamic strain measurements from the wing to estimate the POD expansion coefficient from which an estimation of the velocity in the wake can be obtained. The statistical quantities for the mean flow-field showed that the wing tip vortex dominated. Results show that an estimation of the wake flowfield with the lower POD modes provides a reasonable estimation of the wake flowfield.
