Abstract (en)
[origin: EP2410130A2] The fan-guide wheel blades have upper and lower profiles that form an upper and a lower boundary. The fan-guide wheel blades extends in a bypass duct between an inner and an outer lateral wall in a blade height and whose profiling is formed by multiple radially overlapping aerodynamic profiles. The profiles are determined by a mean line angular distribution with corresponding, overlaid thickness distribution over a chord length.
