 Such a system had first been tried some twenty-five years previously, on the R.30/16 example of the Zeppelin-Staaken R.VI bomber, with the Braun-Boveri supercharger in it powered by a Mercedes D.II engine.Another difference from the Hs 130A was the nose, which was extended forward to offset the weight of the HZ-Anlage engine in the fuselage.Also underwing fuel tanks could be fitted to provide fuel for three engines, and air scoops were fitted under the fuselage to supply the fuselage engine.
