Ao 225

The AGO Ao 225, company designation FP 30, was a twin-stayed heavy fighter-bomber (kampfzerstörer) designed by the German aviation company AGO Flugzeugwerke GmbH and remained in its early stages of development.

Derived from the previous AGO Ao 192 transport aircraft, the Ao 225, characterized by the unusual placement of the engine (or two) inside the fuselage and connected to the propellers located on the Alar attachment edge by transmission shafts, failed to impose itself on competition due to the greater complexity of the system.

Subject to the evaluation of the Technische Amt of the RLM, together with the competitors Arado E 561, Focke-Wulf Fw 57 and Me 210, the project was rejected because it was considered unstable and out dated, as a result the AGO stopped all development.

The number 225 was then reassigned by the RLM to the Focke Achgelis Fa 225 autogyro.
