TheAlbatros C.XIIwas a militaryreconnaissanceaircraft designed and produced by the German aircraft manufacturerAlbatros Flugzeugwerke.

It was developed as a successor to theAlbatros C.X.The C.XII differed markedly from previous Albatros C-type aircraft by adopting an elliptical-sectionfuselagesimilar to that of theAlbatros D.V.The C.XII also featured atailplaneof reduced area, but it retained the wings of the earlier C.X. The C.X entered service with theLuftstreitkräfteduring 1918 and saw active combat during the final months of theFirst World War.Despite the aerodynamic advantages, there was no significant performance increase achieved over the C.X. Examples remained in service until the end of the conflict.

Development

[edit]

The Albatross C.XII originated in the desire withinAlbatrosto produce a superior aircraft to itsC.X.[1]The company's design team opted to incorporate the latest advances from contemporary single-seatfighter aircraft,particularly in the practice ofstreamlining.As a result of this focus, the C.XII was a relatively elegant aircraft for a twin-seater of the era; however, despite its well-proportioned and aesthetically pleasing appearance, the refined fuselage did not contribute to any meaningful improvement in performance.[1]The fuselage was an all-new aspect of the design, which had a natural flow from the airscrew through to the tail unit, which was met via Albatros' distinctive horizontal knife-edge design. The surface area of the fuselage's keel was intentionally minimised.[1]

The structural elements of the C.XII's fuselage were largely reminiscent of the C.X, comprisinglongeronsand formers, the latter having an elliptical cross-section and being composed ofplywood.[1]A combination of pinning and screwing were used to connect the covering with the framework in compact rectangular sections which permitted it to follow thecontoursof the fuselage. Access to the nose-mountedMercedes D.IVaengine, another feature carried over from the C.X, was easily achievable via metal access panels.[1]The new fuselage design necessitated the redesigning of theundercarriage,the forwardstrutsbeing elongated considerably. In spite of this change, the basic structural design of the undercarriage, which comprised V-section steel tubing and elasticshock absorbers,was akin to that of the C.X.[2]

To ensure sufficient directional stability during flight, a small plywood-skinned under-finwas present in the vertical tail surfaces; it also supported the tailskid. The surface area of the fixed tailplane was smaller than that of the C.X to enhance fore and aft sensitivity.[1]This tailplane was braced usingsteelstruts to the vertical fin and had a plywood covering. Afabriccovering and steel tube framing was used for both therudderand the horn-balancedelevator.[1]The wings were largely unchanged from those of the C.X, both in shape and construction method. The aerofoilradiatorarrangement was also retained.[2]

Operational history

[edit]

The Albatros C.XII only became to theLuftstreitkräfteavailable in quantity during 1918, and thus was only used in actual combat for under a year prior to theArmistice of 11 November 1918that ended the conflict.[2]
