摘要

The turbofan driving gear has a core duct (7), a bypass duct (8), and a guide vane collar that is arranged in the bypass duct. A selective positioning of the supporting struts or bifurcations is determined in a certain relation to the guide vanes (10) such that the respective support struts or bifurcation is arranged in each area of the minimal flow that is generated at the pressure side of the guide vanes.
