The Aero A.34 (nickname: Kos , Czech for "blackbird") was a single-engine, two-seat civilian double-decker made by the Czechoslovak manufacturer Aero .
history
The idea to develop a small and light sports and training aircraft came about at Aero in 1929, after similar aircraft had been very successful abroad for several years.
technology
With the A.34, based on the popular and successful Moth series from the British manufacturer De Havilland, a single-handled double-decker was created with upper and lower pairs of wings of the same length, which were designed to be foldable and thus (with a width of 2.91 m) road transport was possible. Fuselage and wings A.34 were fabric-covered wooden constructions, only the ailerons were made of metal, the tensioned and fabric-covered tail unit was a tubular steel construction. On the edges of the lower wings there were tubular brackets to protect against ground contact. The chassis was designed with a split axle, at the rear there was a grinding spur. As standard, the A.34 had double controls for flight training; Pilot and student pilots or passengers sat in open cockpits. The standard version was driven by a Walter -Vega radial engine .
variants
- Aero A.34W
- This type was identical to the basic version, but equipped with an in-line engine of the Walter Junior type with an output of 78 kW (105 PS). This enabled a 36 kg higher payload with the same top speed. Three copies of this type were made.
- Aero A.134
- The A.134 was also identical to the standard version and equipped with a Walter NZ radial engine with an output of 97 kW (130 PS). Only a prototype of this variant was produced ( aircraft registration: L-BASO). With this machine, the pilot Josef Novak took part in the Challenge 1929 , an international flight competition. Due to an engine failure and subsequent crash landing, Novak had to end his participation on August 8, 1929.
