I'm trying to create unstructured mesh of a 3d aircraft wing with ANSYS meshing.
When I use inflation layers (First Layer Thickness) the meshing quality drops and I can barely increase the minimum orthogonal quality from 0,06 and decrease skewness from 0,94 in the area of the sharp trailing edge.
I've used body of incluence around the wing and increase the refinement of mesh but I only get the same or worse results.
My number of elements is about 2-3 millions and I do not want to exceed this number. Furthermore, the geometry of the wing has to be the same as the original, so it is forbidden any radius fillet in the trailing edge.
Can anyone give me a tip what to do?
Any help will be important.

It would help to include a photo of your mesh, and show the bad quality elements.

Here is a capture of the low quality elements in the trailing edge of the wing.
