The FF 54 in its original quadruplane form as tested late 1917 | J.Herris - Friedrichshafen Aircraft of WWI /Centennial Perspective/ (21) |
The Friedrichshafen FF54 is shown here in its original quadraplane form. No doubt the narrow gap between the pair of middle wings created airflow interference between them and contributed to the aircraft's failure. The lower middle wing was then removed and the vertical tail redesigned for renewed flight testing as a triplane. However, the FF54 was not successful as a triplane either. There is some information that indicates the FF54 was also known as the D.III, but that is not confirmed, nor is there any information on an intermediate Friedrichshafen D.II design. No specifications or performance information on the FF54 has survived. | J.Herris - Friedrichshafen Aircraft of WWI /Centennial Perspective/ (21) |
