The Avia BH-26 is a Czechoslovak two-seat fighter and reconnaissance aircraft . It was mainly flown in the 1930s.
history
In 1926 the machine was developed by the Czech designers Pavel Beneš and Miroslav Hajn (hence the abbreviation BH) at Avia in Prague-Vysočany. In addition to reconnaissance , the machine should also be able to conduct aerial combat . The aircraft initially had a one-piece rudder , but after aerodynamic difficulties it was given a rigid tail fin in front . The first flight took place in 1927. Although it was a good machine in itself, only eight copies were built. They came to the central flight school of the Czechoslovak Air Force under the designation B.26for use. While the BH-26 was still in series production, work was being done on the successor, the BH-28 . However, this was never used. With the beginning of the Second World War , the aircraft were briefly used by the German Wehrmacht as courier aircraft. From 1940, however, they were taken out of service and scrapped.
construction
The machine is designed as an all-metal double-decker. The side walls on the fuselage were straight down and had a square cross-section, while round hulls were preferred for models from other manufacturers. The wings were single-spar and connected to each other and to the fuselage with N-stems and were additionally braced. They also had different spans, with the lower wing as a typical Beneš / Hajn construction being slightly longer than the upper one. The engine was a license production of the British Bristol Jupiter IV.
