Brandenburg FD (BI)
   A development of the type D, this aircraft featured the inward-sloping interplane struts to be seen for so long afterwards in the Austro-Hungarian Brandenburg two-seater C types. The tail surfaces were also considerably revised. Aircraft of this type were operated by the flying school of Hanseatische Flugzeug-Werke, Caspar Hamburg-Fuhlsbuttel, and three aircraft went to Austria. Engine, 110 h.p. Benz III. Span, 13.128 m.

Brandenburg Type FD (German B.I)

   The Type FD was a development of the D with revised tail surfaces. This two-seat reconnaissance aircraft had inward-sloping interplane struts that were to be a feature of future Brandenburg aircraft. The Type FD could have two- or three-bay wings. The FD had a divided tailplane, Albatros fashion, with the fuselage separating the two sections of the tailplane. Brandenburg adopted a horizontal tailplane that was in one piece and rested on top of the fuselage. The Type LDD was the machine given the Austro-Hungarian B.I designation and the existence of two different B.I biplanes has caused confusion in many publications. Gray & Thetford give the designation B.I to the Type FD as does the Typenschau under the entry for the Phonix B.I.
   The number of Type FD biplanes purchased by the German Army in 1914 is given as nine, although some sources state only eight. Apparently some of these machines had no military numbers and were probably the property of Brandenburg and were used at the Caspar Flying School at Fuhlsbuttel. (8) However this may be a confusion of the LDD (B.I) biplanes supplied to that school.
   Four ex-German Army FD machines were supplied to Austria-Hungary and were given the serials 05.01 to 05.04. The Austro-Hungarian LFT complained that the 05.04 was shoddily built, and this confirms the German Army's experience with Brandenburg products, that service refusing to purchase any more of the company's aircraft. The LFT quartet were refurbished and ended their days as trainers.

(8) These Militar Fliegerschulen were conducted by private firms working under an official Idflieg program. The school was in charge of an officer who made sure that the curriculum was strictly adhered to.The school had to provide board and lodging to the pupils and the course lasted from four to six weeks, although it often took longer due to weather, lack of aircraft, and other factors. For each successful pupil the school received 8,000 marks.

Brandenburg Type LDD (Austro-Hungarian B.I)

   The Type LDD tractor biplane was the last Brandenburg design of 1914 and placed the pilot in the front cockpit for the first time. The design was refined from the Type FD with wooden engine mounts replacing the steel mount of the FD and further design refinements to the aircraft's structure. The prototype was sent to Austro-Hungary for evaluation and as the performance proved satisfactory it was ordered in large numbers as the B.I (Series 05.1). In addition it was licence built at the Fliegerarsenal Flugzeugwerke at Fischamend (Series 76, 176 and 276). After service as an unarmed reconnaissance aircraft on the Russian and Italian Fronts the type was used as a trainer. Modified to dual control, it was continually refined and was to continue in production for the rest of the war. Post-war small numbers ended up in the air forces of Czechoslovakia, Hungary, Poland and Yugoslavia.
   Of the 102 constructed by Brandenburg, 16 were delivered to the Brandenburg flying School near Hamburg. Approximately 400 were constructed by the Austro-Hungarians till 1918.
   At least 22 B.I trainers were used by the Czechoslovakian air arm post war. B.I 176.95 was the only aircraft of No.4 Squadron at Plzen in November-December 1918.
   The Czechoslovakia firm of Vojenska tovarna na letadla (later Letov) produced a direct copy of the B.I (Fd) as the S.10. This company, originally created by the Ministry of Defence to repair the aircraft, obtained a license to produce the type after the end of the war. Aircraft 176.80 was the pattern aircraft for the series production of the S.10. A total of 51 of these biplanes were manufactured and delivered during 1922-23. The type was very successful and was more popular than its replacement, the S.18 that replaced the type from 1926. They continued in service until the early 1930s and then were sold to aero clubs. Some were still in service when the Germans occupied Czechoslovakia in March 1939.
   The Aero Company also produced the Brandenburg B.I and C.I. The B.I was constructed as the Aero A-1 from September 1919 with 35 examples powered by the 100-hp Mercedes motor being produced. The type could be fitted with a balanced or unbalanced rudder. The horizontal tailplane was redesigned to a half-elliptical shape. The military started to receive the first examples in February 1920 but progress was slow and the last was not delivered until February 1921. The A-1 was not as popular as the S.10 as it had poorer flight characteristics. It was little used in civil aviation due to its unpopularity and also as it was produced in smaller numbers than the S.10.
   Aero Ae-10.21 is preserved in the Czech Air Force Museum in Kbely, Prague.
   Poland had at least 15 Brandenburg B.I trainers in service. These were apparently built (rebuilt?) in 1921 by the Krakowskie Warsztaty Lotnicze for the Polish air arm.
   In Austria a few were built or modified at the Steyr Works as the Steyr School Biplane.
   The type was rebuilt in Hungary in 1927 by the Legugyi Hatosag as the Type BL.1 Kisbrandi. One survived until 1940 in Hungarian air force markings. B.I, civil registration H-MAHE, was in use until 1932 and is preserved in the Hungarian Transportation Museum in Budapest.
   Two civil B.I biplanes ended up in Norway. N-17 was ex-kuk 76.04. It was imported in October 1920 and crashed on 6 March 1921. The second, N-18, ex-kuk 76.05, and was registered to the same owner, M. Wettergren of Oslo. It went to Norsk Flyvebra A/S and survived until 1923, the registration being cancelled on 4 March 1924.

Aircraft Development:

<...>
  In the Autumn of 1914, the new Brandenburg Type “FD” was ready for tests. A development of the Type “D”, the prototype was powered with the 100 hp Argus As.II. After testing, at least 8 other machines were constructed with similar power plants. These aircraft had no Military Number and were probably the property of Hansa-Brandenburg, being used by the Caspar Flying School at Fuhlsbuttel.
<...>
  In the Spring of 1915, the Type “LDD”was ordered in quantity by the Austro-Hungarian Air Service. Machines were required urgently, but production capacity at the Briest plant was fully utilized. An Albatros B.I production line at Phonix was therefore changed over to the Brandenburg type after about the 25th machine and the initial order filled by the Austrian plant.
<...>

P.Grosz, G.Haddow, P.Shiemer Austro-Hungarian Army Aircraft of World War One (Flying Machines)

Brandenburg 05.01 to 05.04

  The first Brandenburg aircraft to reach LA service was the Type FD (work number FD 13) which was accepted on 20 April 1915. This and the three Type FD biplanes that followed were former German air service machines. The Brandenburg Type FD (a lightened and improved Type D) was fitted with either two- or three-bay wings and had a plywood-covered fuselage. A 100 hp Mercedes engine supplied the power. On 27 May 1915, the first three FD biplanes were assigned numbers 05.01 to 05.03, followed by 05.04 (ex-B.1091/14) later. The four biplanes served with Flik 11 on the Eastern Front from April to December 1915. Aircraft 05.02 and 05.03 were equipped with a Type g.2 wireless transmitter. Flik 11 reported in September 1915 that 05.04 was shoddily built and suffered from deformed spars, echoing German air service charges of deficient construction that stopped further procurement of Brandenburg aircraft by the German air service. In the spring of 1916, the four aircraft were withdrawn, refurbished by Fischamend, and placed in training service with Fleks 3, 8, and 11.

Brandenburg B.I Series 05.1

  The satisfactory performance and flight characteristics of the Brandenburg B.I biplane (Type LDD) found the hard-pressed LFT a ready customer, and more of these aircraft were purchased from Germany than any other type. Developed from the Type FD, the B.I saved some 162 kg (357 lb) by replacing the steel engine mounts with wood and resorting to structural refinements. A new feature was the slanted wing struts to obtain equal bending forces over the spar lengths. A 100 hp Mercedes engine supplied the power. Of the total of 102 Brandenburg B.I biplanes ordered, 16 were diverted to the civil Hansa-Brandenburg flying school in Fuhlsbuttel (near Hamburg) where many LFT pilots received their basic training; these were not assigned a serial number.

  In the summer of 1915, the B.I joined Fliks 1, 5, 7, 9, 10, 11, 13, 14, 18, and 20 on the Russian Front as an unarmed general reconnaissance type. A few examples also saw service on the Italian Front with Fliks 2 and 17. Generally free of faults, the B.I was well liked by aircrews. But deliveries were delayed by the death of chief pilot Franz Reiterer and Hauptmann Bela Mogan on 21 October 1915, when the wings of their "training machine" collapsed during a factory acceptance flight. By 23 December 1915 only 33 B.I biplanes had been delivered and service records show that all aircraft starting with 05.44 were assigned directly to training units, primarily Fleks 7 and 8.
  Beginning August 1915, some of the B.I biplanes shipped to the Flugzeugwerk Fischamend for repair were converted to trainers and re-designated B.I (Fd) series 06.5. In addition the Flugzeugwerk began to build a license version in mid-1916 that would total 355 aircraft by the war's end (see Fischamend section for details).

Brandenburg B.I(Fd) Series 06.5

  Conversion of the Brandenburg B.I series 05.1 biplanes to dual-control trainers began at the Flugzeugwerk in August 1915. In addition, the Flugzeugwerk modified 37 B.I aircraft (05.60-05.96) that had been delivered with dual controls already installed. In May 1916, the 49 converted and modified B.I trainers were re-designated Brandenburg B.I(Fd) series 06.51 according to the following table:

  The B.I(Fd) series 06.5, powered by a 100 hp Mercedes engine, was first placed in service at Flek 7 in Parndorf, followed in July 1916 by Fleks 10, 11, 12, and later Fleks 4, 8, 13, and 16. On 1 July 1917, twenty-six B.I series 06.5 biplanes were in service. As the rigors of basic training depleted the original Brandenburg B.I complement, their place was taken by Fischamend-built B.I trainers.


Brandenburg B.I(Fd) Series 75 to Series 279

  In mid-1916, the Flugzeugwerk delivered the first Brandenburg B.I, the only aircraft built specially as a trainer in Austria-Hungary during the war. The B.I trainer, continually improved to lighten the airframe and speed production, kept Fischamend busy until the war's end. Almost all of the B.I trainers were powered by used or rebuilt Daimler and Hiero engines, replacing the original 100 hp Mercedes engines that were no longer available. To compensate for the different engine dimensions and weights, the B.I airframe underwent progressive modification in a variety of series. Inexplicably, the Flugzeugwerk failed to manufacture sufficient replacement parts with the result that in the summer of 1917, some 70 percent of all Brandenburg B.I trainers were grounded for lack of spares.
  Beginning in the summer of 1916, the versatile B.I trainer was flown by every Austro-Hungarian training unit. After the war, many remained on Czechoslovakian, Polish, Yugoslavian and Hungarian territory; many were sold as surplus, and small numbers were built in Poland, Hungary and Czechoslovakia. These formed an important component of the fledgling national air services, and a few B.I biplanes were still flying as late as 1938.
  Unfortunately, an accurate compilation of the structural differences and characteristics (dimension, weight, etc.) that would explain the various series has not been found. Through September 1918, the Flugzeugwerk delivered a total of 355 B.I biplanes. At least 60 were completed in October and in the immediate post-war period. The following tabulation lists all known numbers:

  Although the designations 77.00, 177.00, 178.00 and 179.00 appear in LFT documents, none of these types appear to have progressed beyond the project stage.
