Compressor blades mounting
For the first compressor stage and the fan, the design is simplified by putting the roots of the blades parallel to the shaft. On stages 2 and 3, blades are not long enough, and to finish at the correct angle and not be twisted too much, they need to start at a non-zero angle. That brings problems to the design of the blade socket and fixing. The two pictures below propose a solution to this problem: blades' roots remain linear, the milling of the mounting is linear too, while it's a round part. This makes a strange effect, but allows the blades to be properly fixed on their sides, and if not enough, by a keyed design.
