The Hansa-Brandenburg C.II, company designation K, (Luftfahrtruppen (LFT) series 66.5, 66.8 and 67.5), was a two-seat reconnaissance aircraft built in Germany by Hansa-Brandenburg in World War I, powered by Mercedes D.III or Hiero 6 water-cooled in-line piston engines. [1]

Design and development

The C.II was derived from the earlier Brandenburg KDD prototype, (LFT serial 60.56), and two batches were ordered by the LFT, as the Mercedes D.III powered series 66.5 and Hiero 6 powered series 67.5., in 1916. The 67.5 aircraft were re-serialled in the 66.8 range, but the production contract with Brandenburg was cancelled in November 1916, as the LFT and Austro-Hungarian air ministry preferred production by in-house companies like UFAG and Phönix, which, nevertheless, developed their own designs. [2]

The C.II prototypes followed contemporary Brnadenburg practice with a deep fuselage and a semicircular tailplane sitting on top of the rear fuselage. The characteristic 'Star' or 'Pyramid' wing strut arrangement, consisted of four pairs of V struts attached to the mainplanes at the roots and at 3/4 span converging to a point in the middle of the wing cellule. Unlike the KDD the C.II fuselage did not fill the interplane gap but the pilot was still sat under the centre-section with difficult ingress and egress, particularly in case of an accident. Controls and undercarriage were all conventional with wooden framed fabric-covered control surfaces and tail-skid undercarriage. [2]

Operational history

Two prototypes were built, (66.51 and 66.81), with 66.51 flying in October 1916 and 66.81 flying in June 1917. Flight tests revealed poor longitudinal stability, high landing speed, poor glide ratio and relatively slow climb rate. After testing both prototypes were stored at Aspern until the Armistice and further development was abandoned due to the superiority of the Phönix C.I and UFAG C.I. [2]

The Aero A.14 was a Czechoslovakian biplane military reconnaissance aircraft built in the 1920s. It was essentially a slightly modified version of the Hansa-Brandenburg C.I aircraft, widely-used by Austria-Hungary during the First World War, and for this reason, the aircraft is sometimes referred to as the A.14 Brandenburg. When equipped with a slightly different engine, the aircraft was designated A.15 instead. The two versions were otherwise almost identical.

The Hansa-Brandenburg W.29 was a German two-seat fighter floatplane which served in the closing months of World War I with the Imperial German Navy's Naval Air Service from bases on the North Sea coast. In concept the aircraft was a monoplane version of the biplane Hansa-Brandenburg W.12, although there were many structural differences between the two.

The Hansa-Brandenburg C.I, also known as Type LDD, was a 2-seater armed single-engine reconnaissance biplane designed by Ernst Heinkel, who worked at that time for the parent company in Germany. The C.I had similarities with the earlier B.I, including inward-sloping interplane bracing struts. Like other early-war Austro-Hungarian reconnaissance aircraft, such as C-types of Lloyd or Lohner, the Type LDD had a communal cockpit for its crew.

<span class="mw-page-title-main">Hansa-Brandenburg G.I</span> Austro-Hungarian Bomber Aircraft

The Hansa-Brandenburg G.I was a bomber aircraft used to equip the Austro-Hungarian aviation corps in World War I. It was a mostly conventional large, three-bay biplane with staggered wings of slightly unequal span. The pilot and bombardier sat in a large open cockpit at the nose of the aircraft, with a second open cockpit for a gunner in a dorsal position behind the wings. An unusual feature was the placement of the twin tractor engines. While the normal practice of the day was to mount these to the wings, either directly or on struts, the G.I had the engines mounted to the sides of the fuselage on lattices of steel struts. This arrangement added considerable weight to the aircraft and transmitted a lot of vibration to the airframe.
