For a curved planform, the shock waves are weaker, especially toward the tip of the wing (compare Figures 11(a) and 12(a)), and the pressure variations in the chordwise
direction are smoother (as discussed in a previous work ).
In the trailing edge region, the outer layer of the sheet material would be solid for aerodynamic and fabrication reasons and then cooled via chordwise
channels located in the inner layer of the skin.
At present, the height of VGs is the same as thickness of the boundary layer when VG is used to control flow, so it is necessary to know about the change of boundary thickness of different spanwise and chordwise
location at the blade root so as to provide a reference to design of VGs height.
It exhibited blade twist, extensive chordwise
scratching along the entire span of the blade, and gouges and nicks to its leading edge.
The left propeller blades had displayed light chordwise
The left engine's blades were curled, with polishing of the leading edges and blade faces, along with chordwise
scratches and gouges.
The propeller blades exhibited no leading edge gouging, chordwise
scratching or s-bending.
One propeller blade was fractured near the hub; the other two blades exhibited s-bending, leading edge gouging and chordwise
All three propeller blades exhibited chordwise
scratching and aft bending.
Both propeller blades displayed leading edge gouging and chordwise
The separated tip exhibited chordwise
gouges on its flat face.
Propeller blades displayed chordwise
and spanwise scratches on the camber surfaces.
