This work was inspired by the capturing wind energy at altitudes, known as Airborne Wind Energy Systems (AWES), where the basic principle consist on analyze the maximum energy that can be theoretically extracted with tetheredwings. This work propose and study an Unconventional Fly-Gen Airborne Wind Energy System, that converse mechanical energy into electrical energy by Faraday's law of induction, using mass flow produced on the PT6 enginecowling operating at idle gear. This research shows that is possible to obtain electromotive force by varying the angle between the air mass produced by the engine propeller and axial fan. Finally we found too, that both amplitude andfrequency of the these EMF are inverse functions of cosγ..In this research, was also found that the induced peak power is independent of the type of biofuel with which the PT6 is fed. Is to highlight that this system is the only proposal that exists so far in the literature.
