Anatomy of the Hudson

摘要

The Hudson's airframe was essentially the same as the Model 14 Super Electra, but with additional military equipment. While the wings and empennage were unchanged, the fuselage was heavily modified internally, initially to meet British requirements, and later, with further minor changes, for Australian, New Zealand and Canadian service variations. American equipment was fitted for use by the US services, though this involved more in the way of emergency adaptations than full re-designs. Both the Model 14 and the Hudson derived benefit from the use of Fowler flaps, which, by moving aft as they were lowered, both increased the camber and the area of the wing. This was otherwise of conventional all-metal form and construction, though the Hudson eventually gained self-sealing fuel tanks. Additional tanks could be positioned in the bomb bay and fuselage depending on range and operational requirements. The Hudson and Super Electra were laterfitted with built-in outer wing slots as a fix to a stall and roll problem.
