Abstract: A method for inspecting components includes providing a plurality of different three-dimensional component CAD models with each three-dimensional component CAD model of the plurality of different three-dimensional component CAD models sharing at least one common geometric feature. The method further includes generating an inspection sequence for the at least one common geometric feature, collecting feature manufacturing data for the at least one common geometric feature during manufacturing of a plurality of different components corresponding to the respective plurality of different three-dimensional component CAD models, analyzing the feature manufacturing data associated with the at least one common geometric feature, modifying the inspection sequence for the at least one common geometric feature based on the analyzed feature manufacturing data, and inspecting components based on the modified inspection sequence.

Abstract: A turbomachine having two unducted external fans mounted to contrarotate about a common axis, the fans constituting respectively an upstream fan and a downstream fan, is disclosed. At least some of the blades of the upstream fan carry an air guide device on their radially outer end portions, the air guide device being outwardly oriented on going from upstream to downstream and serving to deflect the vortices that are formed in the vicinity of the blade tips of the upstream fan radially to outside the blades of the downstream fan.
