Classification: CPC B  Y | IPC B

Claim 6:
7. A method of manufacturing a wing comprising:
along a chordwise direction of an airfoil surface of the wing, predicting a plurality of target transition locations under a plurality of design conditions including a plurality of cruise conditions without a trip device, wherein each target transition location is a location where airflow transitions from a laminar boundary layer to a turbulent boundary layer;
identifying a most-downstream target transition location from the plurality of target transition locations, so as to limit downstream movement of transitions from a laminar boundary layer to a turbulent boundary layer under non-cruise conditions; and
incorporating a trip device along a spanwise direction of the wing at a position that is just aft of the most-downstream target transition location to enable turbulent flow, wherein the trip device extends spanwise along an upper surface of the wing.
