C.Owers, J.Herris Hannover Aircraft of WWI (A Centennial Perspective on Great War Airplanes 46)
F 10
The F 10 was a limousine type triplane powered by a 220-hp Benz engine. While the fuselage and biplane tailplane resembled the wartime Hannovers in some respects, it was an entirely new, civilian design. The passenger's cabin had two forward facing seats and two folding seats against the front bulkhead.
In Jane’s All the world’s Aircraft for 1922, under the entry for Hawa it records that the firm had been approached and replied that they "had constructed no new aeroplanes in 1921". The company still had the following machines that it believed would "be of use on German Civilian Services". These were the F 3 biplane that was a "limousine" version of the CL.IIIa, and a new triplane, the F 10 six-seater passenger aircraft. The large triplane was provided with a compartment between the 220-hp Benz Bz.IV engine and the pilot's cockpit that could hold 200 kgs of luggage or mail, and "which acts as a buffer in case of overturning." The biplane tail was a feature of the F 10.
The Inter-Allied Aircraft Control Commission (IAACC) carried out an initial inspection of the Hannover works on 11 March 1919, and reported that 38 CL type fuselages were stored along with three civil aircraft. The IAACC accused Hannover of shipping aircraft and parts to Denmark and Holland. Gorres & Co at Appeldorn in the Netherlands received several shipments of railway wagons of Hannover aircraft and parts in February 1920 according to the IAACC. This was true and the transfer continued up until July. It is known that someone tried to sell Hannover aircraft to the new Polish Government, however, as with so much of this activity surrounding post-war Germany, nothing further is known of these activities.
The F 10 triplane was declared a military aircraft by the IAACC and together with D.82, D.84, and D.110, was impounded by the RTG on 15 May 1920. They were eventually destroyed in August as Hannover did make a claim to have them released as civil aircraft, as they could have been, as they had been completed after the Armistice.
F 12
The F 12 was an unusual twin-engined triplane for ten passengers that was designed in 1919. It featured the biplane tail and truncated nose that allowed the twin engines to be placed close together. Balanced ailerons were fitted only to the lower wing. The last Hannover design, it remained a paper aeroplane. No data are available on this interesting project.
