"ХАЛЬБЕРШТАДТ" D.II/D.III/D.IV / HALBERSTADT D.II/D.III/D.IV

   Последней серийной модификацией стал "Хальберштадт" D.V, появившийся вначале 1917 г. Помимо фирмы-разработчика, его выпускали по лицензии авиазаводы "Авиатик" и "Ханновериш Вагонфабрик". D.V отличался улучшенной аэродинамикой, усиленной конструкцией планера (фюзеляж получил фанерную обшивку) и элеронами с роговой аэродинамической компенсацией. Двигатель - "Мерседес" D-II или "Аргус" As-II.
   Выпуск "хальберштадтов" продолжался до весны 1917 года, после чего их сняли с производства из-за того, что по своим летным характеристикам они значительно уступали "альбатросам". Всего построено 96 экземпляров D.II, 54 D.III и 90 D.V. 33 "пятерки" в том же году были переданы Турции. Также турки получили несколько экземпляров D.II.

Истребитель "Хальберштадт Д. V", хотя и с менее мощным 120-сильным "Мерседесом" или "Аргусом", пользовался куда лучшей репутацией, чем "Роланд". Он был последним среди аппаратов класса Д, выпускавшихся фирмой "Хальберштадт" с 1915 г. и, оказавшись на фронте примерно в начале 1917 г., снискал известную популярность, несмотря на ряд недостатков: в частности, прочность хвостового оперения всей этой серии внушала опасения. Довольно скоро устарев на Западном фронте, модель продолжала использоваться на Восточном и, кроме того, поставлялась в Турцию. Как минимум один из "Ц-пятых" очутился в русском плену, но детали данного происшествия неизвестны (78).

Halberstadt D V
   Virtually a standard D III airframe fitted with either Mercedes or Argus engine, and with modified centre-section struts and ailerons. The D V was reputedly delightful to fly. As may be seen from the national insignia of the aircraft illustrated, some examples were supplied to the Turkish Government. Engine, 120 h.p. Mercedes D II or Argus D II. Span. 8.8 in (28 ft. 10 1/2 in.). Length, 7.3 m. (23 ft. 11 1/2 in.). Climb, ca. 1,000 m. (3,280 ft.) in 3 min.

HALBERSTADT D V Germany

   The D V, which reverted to the two-bay formula, was based on the earlier D III and was similarly powered with a 120 hp Argus As II engine. It differed in featuring aerodynamically-balanced inset ailerons and a redesigned centre section, which, with a simplified cabane structure and a large semi-circular cut-out in the upper wing, offered an improved field of view for the pilot. A single LMG 08/15 machine gun was mounted on the port side of the forward fuselage, but the last D Vs produced were armed with twin synchronised guns. The D V appeared at the Front in the autumn of 1916, some 50-55 being produced by the Halberstadter Flugzeugwerke during the course of that year. A further 37 were manufactured in 1917, these being mostly for use by Turkey where the first D Vs arrived in March 1917. Operating in high temperatures, the D Vs were fitted with additional radiators on their fuselage sides, resulting in some loss of performance. On the Western Front, the D Vs were replaced in the operational role in the summer of 1917, but others remained in first-line service in Palestine well into 1918.

Halberstadt D.V

  The last Halberstadt fighter was the D.V. Very similar to the D.II and D.III, it had the same 120 hp Argus As.II engine used in the D.III, probably due to the high demand for Mercedes engines. However, the preferred 120 hp Mercedes D.II did find its way into some D.V fighters. The single fixed machine gun was now mounted left of the center-line and the cabane structure was redesigned to be more open to provide the pilot a better field of view. Furthermore, the cut-out in the middle of the upper wing was reshaped to be semi-circular.
  The ailerons were within the rectangular planform of the upper wing but were given inset aerodynamic balances.
  At least 31 Halberstadt D.V fighters were supplied to Turkey out of the 57 built. Some of these had Mercedes engines and two machine guns. And some of the Halberstadt D.V fighters sent to Turkey had small side radiators added to them to supplement their standard airfoil radiators in the hot climate in the Middle East.
  Supplying Halberstadt fighters to Turkey late in the war when more powerful Albatros fighters were available may have been due to the delightful flying characteristics of the Halberstadts. Buddecke's experience as the leader of Jasta 4, which was equipped with the Halberstadt D.II, D.III, and D.V types, along with his PLM buddies von Althaus, Hohndorf, Berthold, Frankl, etc., was the determining factor in obtaining the type for Turkey. As Serno's eyes and ears, bringing important experience back to Turkey was key in this decision. It was based on the experience of one man, Buddecke, the "Shooting Hawk" that made that type the main choice for Turkey. Photos show that the type was used there well into 1918 and was still on the airfield until the end of the war. This was important when assigned to inexperienced pilots.
  Records show two guns were sent to Halberstadt on 19 October 1916 for a D.VI fighter but it was not built.
