Looking at the shape is it an extruded 2d object? If so you can run in 2d mode, that'll significantly reduce the cell count. Or use sweep: you need to read up on inflation & sweep as it's a little different to the unstructured inflation approach. Then look at the bulk domain cell size: you want to grow away from the wing to avoid wasting cells but also retain enough mesh to pick up any separation & wake regions. n
