K. u. k. Seeflugzeug Type K (Hansa-Brandenburg FB) 1916

  Как конкурирующая разработка с K-типом инженера Вайхманна (Weichmann), на Hansa-Brandenburg инженером Хейнкелем (Heinkel) был создан похожий самолёт. Основное внешнее отличие заключалось в наклонных V-образных межкрыльевых стойках у законцовок крыльев. В кабине при разведке мог лететь третий стрелок. Этот тип строился также на Oeffag в Винер-Нойштадте. Первые машины (K.174 - 183) поступили от Hansa-Brandenburg и имели двигатели Rapp мощностью 165 л.с. или Mercedes мощностью 160 л.с. Они были поставлены с октября по декабрь 1916 года, остальные - с июня по сентябрь 1917 года. С конца 1917 года на передовой были заменены новыми типами KG.

C.Owers Hansa-Brandenburg Aircraft of WWI Vol.2: Biplane Seaplanes (A Centennial Perspective on Great War Airplanes 18)

Type FB

   The FB was Brandenburg and Heinkel's first flying boat and was used with success by the Austro-Hungarian Navy in the Adriatic. The German Navy was not an enthusiastic supporter of the flying boat and preferred floatplanes; however, they ordered six of the Class C flying boats (MN 511-516). The FB was a large machine with a crew of two or three, two in the main cockpit back in line with the wings while the observer in the bow cockpit had a Parabellum machine gun for defence. The upper wing had a large overhang that was supported by an additional pair of struts that came from the base of the interplane struts. The square tipped planes were swept back and staggered. The single 165-hp Austro-Daimler engine was mounted in pusher configuration supported by a system of V-struts. The rudder was rhomboidal in shape and mounted half below and half above the tailplane. The tailplane was suspended above the hull by a two forward struts and the rudder post. A triangular fin was mounted on top of the tailplane. The elevator was in two pieces. Small floats were suspended under the lower wing.
   Designed for maritime patrol work, they were known as Lohner flying boats in the German Navy.
   FB boat MN 513 was based at Angernsee Seeflugstation where it was used with a number of Friedrichshafen FF33 floatplanes in attacks against the Russians. MN 513, together with Friedrichshafen MN 659, was involved in the shooting down of a Russian M.9 flying boat on 4 July 1916. It appears that it was the only Brandenburg flying boat operated by the station that also operated the Brandenburg GW torpedo aircraft.
   Ltn.d.RMA Friedrich Christiansen flew an FB, MN 516, at Zeebrugge that he named Klar Kimming and this was painted on the bow. The FB could operate in the winter when snow and ice prevented other air activity, the FB boats patrolling the areas where the German minesweepers conducted an endless campaign in trying to keep channels open to allow U-boats access to the North Sea. In a May 1917 return of aircraft all six of the FB boats were still in German Naval service.
   The kuk Kriegsmarine ordered an FB from Brandenburg that was delivered to Pola and received the number K184. It was almost identical with the German prototype MN 511.(2) The type was ordered from UFAG after a number of modifications were carried out to suit the Navy's requirements. The outer parallel interplane struts supporting the wing overhang were replaced by a vee-strut. The fin and rudder were replaced by a completely new design that was connected to the top of the hull. The engine was now a 175-hp Rapp with a different radiator built in Austro-Hungary. The UFAG version could carry a bomb load up to 200 kg.
   The type was ordered from UFAG in seven batches commencing with K168 - K175 ordered before the delivery of the German-built K184. The type had a good performance and proved popular. A second batch, K176 - K173, was ordered on 28 July 1917. K233 saw further modifications introduced with a new tailplane and more powerful engines. The last batch, K251 - K262, was never delivered.
   K222 was captured off Brindisi on 11 August 1917. The machine was described as a "Capa Flying Boat"(3) and was equipped with a 160-hp Austro-Daimler engine No. 7139. The pilot stated that the "engine gives about 200 hp." Two magnetos were fitted but were thrown overboard when capture was certain. The propeller was of ash and mahogany with alternate laminations (diameter 275, pitch 210).
   Two main fuel tanks were located in the hull under the centre section and occupied the full breadth of the boat. A gravity/emergency tank was let into the upper wing centre section. The pilot stated that the machine had an endurance of six hours and a speed of 150 km/hr.
   The front cockpit had a typical German circular gun mounting. "To assist the observer to climb from beside the pilot to the gunner's seat, a strong handle is fitted in the middle of the boat and half of the windscreen in front of the observer is detachable."
   Bombs were carried on the sides of the hull under the planes. "The pilot stated he carried one 150-kg bomb on the port side, and one 50-kg bomb and one 25-kg bomb on the starboard side." The machine gun and ammunition and Very pistol had been thrown overboard.
   The main planes had been torn from the boat and were very badly crumpled up. The wingtip floats were of unusual shape "the nose being covered with paper-mache." The interplane struts were large steel tubes streamlined by a light wooden framework covered with fabric. The struts holding the engine bearers were streamlined by three-ply wood fairings. "The fabric used is reported to be of excellent quality. The lack of copper was very noticeable."(4)
   A total of 66 Brandenburg (UFAG) FB flying boats entered service with the kuk Kriegsmarine. Although this may seem a small number when compared with the attrition of machines involved in the land war, this was a substantial number for a fighting flying boat.
   The UFAG-built K248 was one of two K-boats taken to the US after the war. K248 received Bureau No. A-5807. Its condition merited a Trouble Report of 16 September 1920, but the problems with the boat are not recorded. It was shipped to the Naval Aircraft Factory (NAF) on 20 December 1920, arriving in the following January. On 11 September 1920, the NAF reported that there was a hole about one foot square staved in the forward part of the bottom of the hull. The forward bulkhead was stove in. Ribs were broken in both upper and lower left wings. The cause of the trouble was not clearly evident. It was requested that it be repaired at the NAF. On completion of repairs it was to be sent to Hampton Roads for trials. It was flown to Anacostia in March 1921 before being shipped to Hampton Roads later that month. After trials, if any, it was placed into storage at Hampton Roads where it was subject to a Trouble Report of 6 February 1924. While it was reported to be in a fair condition, it was disassembled with the engine and instruments removed. Experiments and study were now completed with the machine in storage awaiting disposition. It was considered to be of no further use and it was recommended that the hull and wings be burnt but the engine and instruments be salvaged. A-5087 was stricken on 15 March 1924. No thought was given to preserving one of these flying boats.

(2) G. Haddow speculates that K184 may well have been MN 511 given the German Navy's little liking for flying boats.
(3) Allied intelligence was usually very well informed; however, it appears that in this case the nick-name for the Brandenburg was accepted as the official name for the flying boat. In Jane's All the Worlds Aircraft for 1920 K222 is described as a "Kappa"flying boat.

The prototype Brandenburg FB displays the MN 511 in small numerals on the rear of the hull. This photograph is thought to show the machine after the rudder was modified to add a horn balance, (via AHT AL0354-078)
The Hansa-Brandenburg FB is yet another example of buying small numbers of many types. In this case, the navy purchased six only of this 150hp Benz Bz III powered two seat flying boat reconnaissance scout. Essentially a German-built version of the Lohner scouting flying boats, the performance details of the FB are lost, but its overall capability must have been close to that of the Lohner Type L.

With a wingspan of 'only' 16.3m (53.48ft) and an overall length of 12.2m (40.3ft), the Brandenburg FB seaplanes like 'K168' were known to the Anglo-Italians as 'small Kapas' - the W. 13s being called 'large Kapas'. They belonged to a family of flying boats first conceived in Germany by Ernst Heinkel for Hansa-Brandenburg and known as the Type FB. In Austria-Hungary these seaplanes were built by UFAG and known as the UFAG Type K; 'K231'came from the fifth UFAG-built batch and was powered by a 160-hp Austro-Daimler engine.

UFAG-built K248 at Anacostia, 24 March 1921. This machine was reconditioned by the US Naval Aircraft Factory, Philadelphia, to bring it to flying condition. The modified tailplane of this batch is well shown. As Bureau No. A-5807 it was painted in the standard USN color scheme of US Navy grey overall with the star in circle national markings. To date it has not proved possible to unearth the USN report on this boat.
