From the flight test and relative aerodynamic analysis and test for the flexible wing miniature unmanned vehicle,the method on dealing with the aerodynamic feature,flight feature and operational stability has been researched.

To our best knowledge, we are the first in China to explore design, construction and operation of such a MAV with a flexible wing.

The design of a flexible wing can enhance the capability of gust resistances for a micro air vehicle (MAV).

Aerodynamic experimental investigation for mechanism of lift and thrust of flexible flapping-wing MAV;

The paper also computes the flapping power and flapping efficiency of the flexible flapping-wing, and their changes with flapping angel, velocity, and so on.

As solution of unsteady flows due to flexible flapping-wings is not possible by mesh deformation and overset grids alone unless grid regeneration is employed,an effective strategy which combines mesh deformation based on Delaunay graph mapping and unstructured overset grids is proposed in this article.
