Fokker V.26 / V.27 / V.29 / V.37

In early 1918, Fokker produced several rotary-powered monoplane prototypes, submitting V.26 and V.28, small parasol-winged monoplanes with his usual steel-tube fuselages, for the second fighter trials at Adlershof in May/June 1918.

V.28 was tested with the 108 kW (145 hp) Oberursel Ur.III and 119 kW (160 hp) Goebel Goe.III, though neither of these engines were ready for operational service.

The V.26 used the standard Oberursel Ur.II engine, producing only 82 kW (110 hp).

The engine was obsolete but the low drag of the V.26 and light weight meant that it was still quite fast.

The Fokker designs were only barely beaten by the Siemens-Schuckert D.III with the complex bi-rotary Siemens-Halske Sh.III engine and the V.26 was ordered into production as the Fokker E.V. 

Four hundred were ordered immediately with either the Ur.III or Goe.III.

Because neither engine was available in any quantity, all production examples mounted the Ur.II.

The Fokker V.27 was a German parasol-monoplane fighter prototype designed and built by Fokker-Flugzeugwerke.

The V.27 was little more than an enlarged V.26 (prototype for the D. VIII) with a 145 kW (195 hp) Benz Bz.IIIb liquid-cooled inline engine.

Once again, Fokker pursued similar aircraft with both rotary and inline engines.

Fokker submitted the V.27 at the second fighter competition at Adlershof in May/June 1918.

The V.37 was a ground-attack variant of the V.27.

It was fitted with extensive armour plating to protect the pilot and engine.

Neither the V.27 nor the V.37 were placed in production.
