A novel design approach for the centrifugal compressor blade is proposed in this paper. It is set up based on the offset theory and line geometry. The designed blade surface is represented as a tool path, which consists of two guide curves. It can be manufactured by flank milling method with a cylindrical cutter. The drive surface is a ruled surface that is(More)
This work investigates the impact of Sn segregation on the growth of Ge1−xSnx epi-layers using a reduced pressure chemical vapour deposition (RP-CVD) system with the common precursors Ge2H6 and SnCl4. The investigated samples were grown on top of a 1 µm thick relaxed Ge buffer layer with different amounts of Sn incorporation, achieved by increasing the(More)
