THERMOELECTRIC GENERATORS FOR AEROSPACE APPLICATIONS: DEVELOPMENT EXPERIENCE AND FUTURE CHALLENGES

Popis výsledku v původním jazyce

An idea of thermoelectric generators for applications in aerospace is nothing brand new. The related literature records can be traced back to mid 60s. This idea has been driven by a desire for a maintenance-free electric energy generator with no movable parts and high resilience to the ambient harsh environment. The most promising applications which have been studied are backup power supplies for on-board systems and low-power supplies for sensors within inaccessible spots in the aircraft structure. The on-going era of devices’ miniaturization provides a unique opportunity for thermoelectricity renaissance in aeronautics. This paper deals with a comprehensive overview of the development process which was carried out for the technology demonstrator of Backup Thermoelectric Generator for Aerospace Applications (BTEG). The technology demonstrator is intended to utilize waste heat from aircraft engine case. This thermoelectric generator is based on a MEMS technology providing a high degree of spatial integration. The MEMS core is supplemented with thermomechanical integration assembly and power conditioning electronics based on commercial of the shelf components. The development process consisted of several consecutive steps including requirements definition, simulation modelling, and components development and testing. The final integration testing was carried out on a small turboshaft engine testbed. The concluding part of the paper outlines the promising application areas for thermoelectrics on a future aircraft.
