В.Обухович, А.Никифоров Самолеты Первой Мировой войны


В середине 1918 г. на базе FF 39 был создан еще один самолет - FF 59с. Новая машина имела измененное хвостовое оперение. Коробка крыльев стала безрасчалочной. Межкрыльевые стойки были сдвинуты к концам крыльев для того, чтобы была возможность вести огонь из турельного пулемета. Кроме того, было изготовлено по одному самолету модификаций FF 59а и FF 59b, которые отличались хвостовым оперением.

Friedrichshafen FF 59a, FF 59b
  Two versions of the FF 59 with modified tail surfaces, which led eventually to the FF 59c, for details of which see following page, all general details being applicable.


Friedrichshafen FF 59c
  Supplied from June 1918 onwards, the FF 59c reverted to the less powerful 200 h.p. Benz engine and was little more than a modified FF 39 fitted with both transmitting and receiving radio equipment. The inboard bracing cables were deleted, thus enabling the gunner to hazard a shot forward between the wings should the necessity arise. Span, 17.8 m. (58 ft. 4 7/8 in.). Length, 11.3 m. (37 ft. 1 in.). Height, 4.25 m. (13 ft. 11 3/8 in.). Area, 71.5 sq.m. (772 sq.ft.). Weights: Empty, 1,588 kg. (3,494 lb.). Loaded, 2,248 kg. (4,946 lb.). Speed, 142 km.hr. (88.75 m.p.h.). Climb, 1,000 m. (3,280 ft.) in 8.9 min., 3,000 m. (9,840 ft.) in 49.7 min. Duration, 5 2/3 hr. Armament, one manually operated Parabellum machine-gun in rear cockpit.

SOME FRIEDRICHSHAFEN "MILESTONES"

"The F.F. 59B
  "As a result of the requirements for reconnaissance machines to be capable of defending themselves against attack, and even under suitable conditions to go over to attack, the F.F. 59C shown in Figs. 32 and 33 was so designed that with the rear machine gun the gunner could fire forward between the first pair of interplane struts and the propeller disc, whilst the fixed machine gun was worked by the pilot. In order to give as large a field of fire as possible to the rear machine gun, the inner front interplane strut was moved outwards slightly farther than the corresponding rear strut, and the wing bracing of the inner bay was entirely omitted.

Marine Number 1822 was the first prototype FF59.The vertical tail surfaces were mounted under the tailplane to maximize the observer's field of fire in a manner reminiscent of Brandenburg practice. (The Peter M. Bowers Collection/The Museum of Flight)

This photo shows Marine Number 1822 after the vertical tail surfaces were modified. Now the fin projects above the fuselage to improve flying qualities but compromising the observer's field of fire.

The FF59 was developed from the FF49 with particular attention to giving the observer the maximum field of fire.
