Abstract : Flight tests of a commercial aircraft consist in gathering data during flight to validate aircraft design. However they are very expensive for various reasons. One of them is that most of the sensors implemented to collect data are wired. As an example, for the sole system that monitors the vibrations onboard a large (more than 100 seats) aircraft, more than 100 sensors may be deployed. Such networks are complex to implement, mainly because of the required wiring. A wireless solution is therefore of great interest; however, such a cable-less implementation implies both wireless transmission of data together with energy autonomy. The purpose of this work is therefore to describe a design of a power generation system, focusing on photovoltaic, together with the associated management strategies for an autonomous wireless sensor network deployed for large aircraft in-flight tests. This work is a part of SACER project. The main requirements are related to the thickness of the system (less than 3,2mm in order not to disturb the aerodynamic air flow) and the output power (3 W per sensor node in order to power the sensor, data processing and transmission system). In addition, the system has to properly work at extremely high and low temperature (-50 to 100°C). Our system consists of three primary components to consider: Energy Harvesting system, Energy storage device and Energy management system. In this work, we firstly present the comparison of the performance of different photovoltaic technologies at different temperatures concerning their availability and achievable power density in aircraft applications. Secondly, we will investigate the possibility of using batteries and supercapacitor. Finally the power management system, composed by a photovoltaic panel, a power conditioning (MPPT function), supercapacitors and a DC/DC regulator, is presented.
