Turbofan for aircraft, has fan conduit with external and internal rotation walls connected by single tubular radial arm permitting passage of electrical cables and fluid conduits e.g. air conduit, oil conduit and fuel conduit

摘要

The turbofan has a fan conduit (28) extending around an engine of the turbofan and provided with external and internal rotation walls (30, 32) that are coaxial and define an annular secondary flow circulation space between the walls. The rotation walls are connected by a single tubular radial arm (34) permitting passage of electrical cables (54) and fluid conduits e.g. air conduit (56), oil conduit (50) and fuel conduit (52). The arm i.e. lower arm, vertically extends towards bottom from the wall (32).
