The Avia BH-6, an experimental fighter aircraft, was manufactured in Czechoslovakia in 1923.
This unique aircraft featured a single-bay biplane design and was developed alongside the BH-7, sharing similar fuselage and tail characteristics.
Notably, the BH-6 had wings of unequal span, with the top wing being shorter than the bottom wing.
The top wing was connected to the bottom wing through a single I-strut on each side, sloping inwards from bottom to top.
Unlike traditional designs, the top wing was not supported by cabane struts but rather by a single large pylon attached to the fuselage.
Unfortunately, both the BH-6 and the BH-7 experienced crashes during their testing phase, leading to the abandonment of this particular aircraft configuration.
BH-8
In 1923, Czechoslovakia introduced the Avia BH-8, a prototype fighter aircraft.
This aircraft was created as an improvement upon the BH-6 design, which had faced numerous challenges.
The BH-8 featured an unequal-span biplane structure and retained the unique wing cellule design of its predecessor.
Although the BH-8 showcased improved flying capabilities during its test flights, it ultimately lost its development momentum to the BH-17, another variant of the original design.
