J.Herris Aviatik Aircraft of WWI (A Centennial Perspective on Great War Airplanes 10)

Aviatik F.I

   In September 1918 Idflieg defined a new aircraft class, "F", which stood for Fernaufklarerflugzeuge or long-range aerial reconnaissance aircraft. The classification was sent simultaneously to Rumpler, Halberstadt, L.V.G., Albatros, Aviatik, D.F.W., L.F.G. Roland, and Sablatnig, who were required to satisfy the following requirements:
• Maximum altitude (8,000 m)
• Speed at high altitude (160-170 km/h at 7,000 m, more than 140 km/h at 7,400 m)
• View for the pilot downward and to the sides, and the possibility to vertically see the ground
• Observer space only for photographic equipment.
• Parachute.
• Fuel tanks for 325 gallons of gasoline, either a tank with two separate chambers or a double-walled, bullet-resistant tank
• Wireless transmitter with heating
• Liquid oxygen for breathing at altitude
• A fixed forward-firing machine gun and a flexible machine gun in a rotating ring for the observer.
   A number of engines were suggested, including the 350 hp Benz Bz.V V-12, the 350 hp Man V-10, the 260 hp Mercedes D.IVb, the 370 hp BMW V-12, and the 300 hp BuS.IVa six-cylinder. Examples of the Benz Bz.V V-12 were delivered in September. A Roland F.I to this requirement was ordered in September and delivered in December.
   A competition between F-types similar to the fighter competitions started in September but the Armistice brought the competition to a halt.
   The aircraft that was completed postwar as the Aviatik F Limousine for two passengers and mail was almost certainly the Aviatik F.I long-range reconnaissance design converted to a transport. The Aviatik F was a large, three-bay biplane that bore a marked resemblence to the Aviatik D.VII fighter. The fact that a Benz Bz.V V-12 was installed, one of the engine types recommended for the F-class, and the fact that the aircraft was completed in the first half of 1919 indicate that it was designed during 1918 for the F-class requirement. Furthermore, a photo of the aircraft under construction in the factory shows the rear cockpit ready for installation of a gun ring, while another photo of it outside the factory shows it now being built as a transport.
   The Aviatik F was completed as a transport; whether it flew is not known for certain but is likely given that it was completed.

Журнал Flight

Flight, September 11, 1919.


   For mail and passenger carrying the firm has produced a limousine to be known as

The Aviatik, Type F
   This machine, a sketch of which is published herewith, has the following dimensions; Span, 15 m.; Length overall, 7 m. 90; height, 3 m. 100; weight empty, 1,050 kg.; fuel and occupants. 315 kg.; other load, 250 kg.; total weight, 1,615 kg. Sufficient fuel is carried for a flight of 3 hours, so that the range is approximately 525 km. The power plane is a twelve-cylindered Vee engine of 300 h.p. The speed is estimated at 175 km./hour at 2,000 m., and climb the 5,000 m. in 35 mins. The ceiling will be about 6,500 m.

The Aviatik F, completed postwar as a transport, was apparently converted during production from the Aviatik F.I designed in response to Idflieg's new "F" class long-range reconnaissance aircraft.

The Aviatik F during postwar flight evaluation. There are no records of it having flown, but that is highly likely considering that it was completed. Use of a two-bladed instead of A four-bladed propeller seems unusual considering the 350 hp delivered by the Benz Bz.V V-12.
