The Aero A.8 was the last realised construction of ing. Karel Rösner in the Aero factory. It was a passenger biplane for 4 passengers. Unlike most passenger airplanes of the time, which had the pilot seat positioned behind the wings, the pilot of A.8 was sitting under the leading edge of the wing. During the flight tests the airplane crashed in an accident into the wooden building of Main Aviation Workshops in Kbely. The development of the airplane was then abandoned. [1]

Aero Vodochody company in the Czech Republic

Aero Vodochody is a Czech aircraft company. The factory and factory airport is located in Prague-East District, on the territory between Vodochody and Odolena Voda region. It was active from 1919, notable for producing the L-29 Delfin, L-39 Albatros, L-59 Super Albatros, and the L-159 Alca military light combat jet. From 1929 until 1951 Aero also made a range of small and medium-sized cars with two-stroke engines, and in 1946–47 it built the Škoda 150 truck under licence.

Biplane airplane wing configuration with two vertically stacked main flying surfaces

A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a similar unbraced or cantilever monoplane wing. Improved structural techniques, better materials and the quest for greater speed made the biplane configuration obsolete for most purposes by the late 1930s.

Leading edge

The leading edge is the part of the wing that first contacts the air; alternatively it is the foremost edge of an airfoil section. The first is an aerodynamic definition, the second a structural one. As an example of the distinction, during a tailslide, from an aerodynamic point of view, the trailing edge becomes the leading edge and vice versa but from a structural point of view the leading edge remains unchanged.

General characteristics

Maybach Mb.IVa I-6 piston aircraft engine

The Maybach Mb.IVa was a water-cooled aircraft and airship straight-six engine developed in Germany during World War I by Maybach-Motorenbau GmbH, a subsidiary of Zeppelin. It was one of the world's first series-produced engines designed specifically for high-altitude use. It was quite different engine design than the previous Maybach Mb.IV, not just a simple modification.

  • Maximum speed: 140 km/h (87 mph; 76 kn)
  • Cruise speed: 105 km/h (65 mph; 57 kn)
  • Range: 600 km (373 mi; 324 nmi)
  • Wing loading: 36.5 kg/m2 (7.5 lb/sq ft)
