Единственный самолет W 27 отличался I-образными межкрыльевыми стойками и двигателем Бенц Bz.III (195 л. с.). W 32 был похож на тот же W 27, но оснащался двигателем Мерседес D.III (160 л. с).

Brandenburg W 27
  A development of the W 12, the W 27 did not differ drastically from the earlier machine; most noticeable variation was the "I"-type interplane and centre-section struts. Only a single aircraft was built, No. 2202, and it was powered with the comparatively new 195 h.p. Benz Bz IIIb engine, an eight-cylinder vee type. The performance did not warrant a production order, and the W 27 finished its days on training duties. Engine, 195 h.p. Benz IIIb. Span, 11.2 m. (36 ft. 9 in.). Length, 9.23 m. (30 ft. 3 1/2 in.). Height, 3.057 m. (10 ft. 0 1/4 in.). Area, 36.06 sq.m. (389 sq.ft.). Weights: Empty, 1,109 kg. (2,440 lb.). Loaded, 1,619 kg. (3,562 lb.). Armament, one Parabellum and two Spandau machine-guns.


Brandenburg W 32
  A still further development of the W 12 two-seat patrol fighter theme was the W 32, in effect a re-engined W 27. Five machines were originally scheduled: Nos. 2282-2286, but No. 2285 and No. 2286 were cancelled in April 1918. Engine, 160 h.p. Mercedes D III. Span, 11.2 m . (36 ft. 9 in.). Length, 9.23 m. (30 ft. 3 1/2 in.). Height, 3.25 m. (10 ft. 7 7/8 in.). Area, 36.06 sq.m. (389 sq.ft.). Weights: Empty, 1,063 kg. (2,339 lb.). Loaded, 1,544 kg. (3,397 lb.). Climb, 1,000 m. (3,280 ft.) in 11.6 min. Armament, one Parabellum and two Spandau machine-guns.

BRANDENBURG W 27 & W 32 Germany

  Early in 1918, it was suggested to Ernst Heinkel that a successor to the W 12 two-seat fighter would soon be required if the German Navy was to maintain its superiority over Allied types being encountered over the North Sea. To conserve valuable time, Heinkel installed the new 195 hp Benz Bz IIIbo eight-cylinder Vee engine in a modified W 12 airframe and a 160 hp Mercedes D IIIa in a second W12. Wing span and gap were reduced, stagger was increased to improve visibility, and aerofoil-section I-type interplane struts were adopted. Armament comprised two synchronised 7,92-mm LMG 08/15 machine guns and one 7,92-mm Parabellum on a flexible mount in the rear cockpit. The Benz-engined prototype received the designation W 27 while that powered by the Mercedes engine became the W 32, but both were found inferior to the W 29 monoplane and no further development was undertaken. The following data relate to the W 27.

Max speed, 106 mph (170 km/h).
Empty weight, 2,445 lb (1109 kg).
Loaded weight, 3,569 lb (1 619 kg).

Type W.27

  The W.27 was a 1917 development of the W.12 two-seat fighting floatplane. The machine was powered by the 195-hp Benz Bz IIIb Vee-eight engine. The fuselage was virtually the same as that of the W.12 but the wings were different and featured "I" interplane struts. The Brandenburg three-view drawing of the Seekampf-Flugzeug-Type WXXVII shows a neatly cowled engine with a spinner to the propeller similar to the W.32. Performance was not improved enough to warrant production. All three were constructed but only photographs of MN 2202 appear to have survived. The type ended its days as a training machine. Unlike the Allies, Germany had problems with developing a Vee-eight engine during the war years and the failure of the W.27 may have been attributed to its engine.

Brandenburg W.32
  
  The W.32 was an early 1918 development of the W.27 with the standard straight-six 160-hp Mercedes engine, the Typenschau stating that the machine was a conversion of the W.27. It would seem from the allocation of the Marine Numbers that the W.32 was Brandenburg's attempt to salvage the effort that went into the development of the W.27. Five W.32 biplanes were ordered but only the first three were built, the last two being cancelled in April 1918 so that Brandenburg could concentrate on the superior W.29 monoplane. MNs 2282 - 2286 were allotted to these Class C3MG machines. They were delivered to Kiel-Holtenau in early 1918.

Brandenburg W27

  The W27 differed from the W12 primarily by its use of I-type interplane struts and a 195 hp Benz Bz.IIIb V-8 engine. These were class C3MG, so armament was two fixed Spandau machine guns for the pilot and one flexible Parabellum machine gun for the observer. Three aircraft, Marine Numbers 2201-2203, were built, but the engine was not in full production and the aircraft were used as trainers.


Brandenburg W32

  Yet another W12 derivative was the W32, which appears to have been a W27 fitted with a 175 hp Mercedes D.IIIa engine. Again three aircraft were apparently built; Marine Numbers 2282-2284. The first aircraft, #2282, was class C3MG; the other two were class C2MG HFT. Dimensions were the same as the W27 and the W32s were accepted about the end of June 1918. By this time the faster W29 and W33 monoplanes were in production and an improved W12 was unnecessary.

Only photographs of W.27 MN 2202 have survived. Brandenburg plans show a neatly cowled engine with spinner.
The W 27 (photo) and W 32 were both derived from the W12, with new Benz and Mercedes engine installations respectively.

Marine #2202 was the second Brandenburg W27 prototype. The W27 was a development of the W12 with streamlined struts and a 195 hp Benz Bz.IIIb V-8 engine. One drawback of the struts was that they blocked some of the crews' field of view. The engine never reached full production and the W27 was limited to only three prototypes.

W.32 MN 2282, presumably at Warnemunde for the SVK testing of the type. The MN is repeated in small numerals on the bottom of the rudder, and on other components. The W.32 was a handsome machine with its neatly cowled engine and spinner.
The W32 was a development of the W27 with a 175 hp Mercedes D.IIIa engine. The aircraft was no improvement over the W12 and was limited to three prototypes.
