“…Previous publications by the authors [6,7] have presented a coupled fluid-structure interaction method efficient enough to be used for conceptual design of micro air vehicles. An advanced potential flow model is used to calculate aerodynamic performance and loading, while a simplified finite element structural model using frame and shell elements predicts the wing deflection due to aerodynamic loading.…”

The reliability of sustained flight of a thin wing Micro Air Vehicle (MAV) is studied by considering both structural and aerodynamic parameters as uncertain (random) variables. The structural design variables of the wing that are considered to be random are shell thickness, frame elastic modulus, shell elastic modulus, shell cross sectional area, frame material density, and shell material density. The random aerodynamic variables include the free stream velocity and the air density. In the reliability assessment, both the Monte-Carlo simulation method and the Hasofer-Lind-Rackwitz-Fiessler analytical method are used in conjunction with an efficient fluid-structure interaction model to calculate the probability of the MAV achieving adequate lift. The lift reliability, calculated using both methods, is compared, insight is given into influential uncertain parameters, and future reliability-based assessment questions are posed.

“…Of course, more practical numerical tools [27][28][29] are existing but they are devoted to computational intensive studies such as flight mechanisms. Few of them have been used for sizing purposes [21,[30][31][32][33] and even fewer for preliminary design tasks [34,35].…”

This paper addresses the design of the elastic structure of artificial wings to optimize their dynamical behaviour to reproduce insect wings kinematics. Our bioinspired kinematics is based on the original concept of using the resonant properties of the wing structure in order to combine the motion of two vibration modes, a flapping and a twisting mode, in a quadrature phase shift. One way of achieving this particular combination is to optimize the geometry and elastic characteristics of the flexible structure such that the two modes are successive in the eigenspectrum and close in frequency. This paper first proposes a semi-analytical model, based on assembled Euler-Bernoulli beams, to understand, compute and optimize the artificial wing dynamic vibrations. Then, using this model, it is shown that it is possible to obtain several artificial wing structures with a flapping and a twisting mode close in frequency. Finally, experimental validations are performed on micromachined insect-sized prototypes to validate the model and the concept.
