AVIA BH-9 'BOSKA'

The Avia BH-9 was a Czechoslovak low-wing sports and training aircraft from the interwar period. The drive was provided by a single engine Walter NZ 60 with a power of 60 HP. The prototype flight took place in 1923. In total, about 10-15 aircraft of this type were built. The machine did not have a permanent on-board armament. The BH-9 was created as a development of two other Avia plant structures: BH-1 and BH-5. The changes mainly concerned the strengthening of the airframe structure, improvement of its aerodynamics and the use of a completely new power unit, produced in Czechoslovakia. The Czechoslovak Air Force became interested in the new plane, which purchased 10 and used them as training and liaison planes under the designation Avia B.9. The Avia BH-9 aircraft turned out to be a successful design, capable of winning international aviation competitions, such as the Coppa D'Italia in 1925.
