Foam bonded on metal is a common design in space applications. Despite the fact that high efficacy bonding processes exist, there is no a priori insurance in the bonding quality. So, careful bonding inspection is needed as adhesion loss can be critical during chronology. for small structures there is no real problem, as good NDT methods are available. But, at large scale, not only the quality of the control but also the productivity of the tesing process must be relevant. Such constraints have been taken into account, at Onera, in developing a tool which can be used in industrial environment. Techniques used are not very original and their association has been broadly developed and used in the past. But, the need arose for such a method in inidustrial environments with qualities like fast response, full-field and robust interpretation. This paper describes the ways used to cope with these constraints in designing a tool which seems to be compatible with the targeted application.
The Micro Aerial Vehicle (MAV) represents a strategic and industrial goal. The challenge is truly technical, as the needs are very specific in terms of mission and efficiency. The aerospace French agency (Onera ) has launched an internal program on that purpose including many research topics, essential to understand how to reach the goals. Thus, aerodynamic (generally unsteady with low Reynolds number), structural dynamics, propulsion, actuation, control,.. are being studied in this field. On a structural and mechanical actuation point of view, presently our main interest, the problem is already very large. So before analyzing and formulating, we found not so meaningless to look how nature proceeds and to start a design study with a "biologically-inspired" approach (dragonfly).
