Abstract

Dans un aspect, un système de propulsion comprend un moteur et un ensemble dentraînement couplé au moteur comprenant un premier arbre de transmission pouvant tourner dans une première direction autour dun premier axe, une première soufflante couplée au premier arbre de transmission afin de tourner dans le premier sens et un ensemble embrayage pour mettre hors prise sélectivement la première soufflante du premier arbre de transmission. Dautres aspects peuvent être décrits.
