BRANDENBURG L 16 German

   A single-seat equi-span fighter triplane, developed for the Austro-Hungarian K.u.k. Luftfahrttruppen, with aerofoil-section I-type interplane bracing struts, the L 16 was powered by a 185 hp Austro-Daimler six-cylinder water-cooled engine and was intended to carry an armament of two synchronised machine guns. Various coolant radiator arrangements were evaluated on the single prototype built, but the fighter offered insufficient promise to warrant series production and development was abandoned.

Max speed, 118 mph (190 km/h).
Empty weight, 1,631 lb (740 kg).
Loaded weight, 2,061 lb (935 kg).
Span, 29 ft 6 1/3 in (9,00 m).
Length, 23 ft 7 7/8 in (7,21 m).
Height, 12 ft 1 2/3 in (3,70 m).
Wing area, 360.59 sq ft (33,5 m2).

Type L 16
  
   Brandenburg was not immune to the triplane craze and when specifications of a captured Sopwith Triplane were received from Flars a single-seat triplane fighter was soon designed around a 200-hp Daimler engine. Of large dimensions, the L 16 was completed by December 1917. It was a neat looking triplane with equi-span wings. The I-type interplane struts had an airfoil section. Like so many other triplane prototypes it remained a single example. It was sent to Lloyd where it was evaluated with the serial 40.15. Details of its first flights are unknown. By March 1918 it was hangared at the Phonix facilities at Aspern. Flown only occasionally, the triplane was obsolescent and remained with Phonix till the war's end.

Brandenburg L 16

  Upon receiving technical specifications of the Sopwith Triplane from Flars, Brandenburg replied on 26 June 1917 that construction of a prototype triplane would begin immediately, with completion optimistically estimated in 5 to 6 weeks. Static calculations for the triplane fighter, known as the L 16 - Brandenburg's last landplane of the war - were submitted for approval on 13 August 1917, and later that month Brandenburg requested a 200 hp Daimler engine for installation. When Flars engineering representatives inspected the completed triplane in Briest on 1 December 1917, they were struck by the "surprisingly large dimensions." The date of the L 16's first flight is unknown. Brandenburg technical data sheets lay claim to an incredible climb rate of 2000 meters (6562 ft) in 3 minutes (with a 185 hp Daimler engine), figures surely based on slide rule calculations and not on actual results. On 1 March 1918, the L 16, now in Phonix's hands, was hangared at Aspern but flight activity remained sporadic. Surpassed by modern biplane fighters with superior performance, the heyday of the triplane was history. On 20 June 1918, the L 16 was reported stored at Phonix where it remained until the war's end, at which time Phonix received payment for the prototype.

Three other triplane fighter essays of 1917 were the rotary-powered Euler Dr I, the 185hp Austro-Daimler powered Hansa-Brandenburg L 16 (photo) and the Korting engined DFW Dr I.
For the initial flight trials at Briest, the Brandenburg L 16 prototype was fitted with temporary strut-mounted radiators for the 200 hp Daimler engine.

For initial trials the L16 prototype fighter had two large radiators fitted on the centre section struts.

The Brandenburg L 16 at Aspern had a single radiator mounted forward of the middle wing, an indication it might have been reengined with a 185 hp Daimler engine.

A single radiator is mounted in front of the middle wing at the fuselage. The middle wing was mounted on the struts independent of the fuselage.

Photographed at Aspern in 1918, the Brandenburg L 16 had a slightly modified rudder. The middle wing, mounted on struts, was independent of the fuselage. The original photograph was printed on bubble paper. (AHT AL0579-067)

Evaluated by the Austro-Hungarian air arm in 1917, the L16 triplane lacked promise.
