Blackburn H.S.T.10
The Blackburn H.S.T.10 (sometimes known as the Blackburn B-9) was a 1930s British twin-engined commercial monoplane, designed and built by Blackburn Aircraft at Brough, East Yorkshire. Design and development The H.S.T.10 was a low-wing cantilever monoplane powered by two Napier Rapier, Napier Rapier VI engines. It had a retractable conventional landing gear with an enclosed cabin for two pilots and twelve passengers. It was fitted with a single-spar all-metal wing. The single tubular spar, known as the Blackburn-Duncanson, had previously been tested on a Blackburn Segrave. Claimed to be lighter than a two spar design while also stiff in "torsion and bending", the spar also served as the fuel tank. Intended to be "high speed" by careful attention to shape and removing "protuberances" with retractable undercarriage, the expected performance was 320 miles with two pilots and twelve passengers which increased to 1000 miles with both pilots and five passengers. The pilots had indiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monoplane
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower a ...
