What is it about?
The article analyzes the forces of the flapping wing with experiments in a wind tunnel, comparing them to an aerodynamic 2D model. We adapt the parameters of the wing to be able to apply these models to a 3D case.

Why is it important?
This is the first thorough experimental analysis of flexible flapping wings. The comparison allows us to understand the range of applicability of 2D models. This work is quite relevant for the design of bio-inspired aerial robots that mimic avian flight.
Perspectives
This article demonstrates that the trends observed in 2D aerodynamic models of flexible flapping wings are remarkably similar to those found in experiments. Although this work represents a significant step forward in the analysis of flexible flapping wings, further work is needed to obtain more accurate models that can be used to estimate the forces.
