Handley Page Type G
Résumé
The Handley Page Type G was a two-seat British biplane, designed by Handley Page that first flew in 1913. Only one was built.
The Type G was the first biplane wholly designed by Handley Page. In 1924 the early Handley Page types were give a retrospective design number and the Type G became the H.P.7. Its immediate precursors were monoplanes (Types D, E & F), all of which used a wing of very unusual planform, having a strongly curved leading edge together with a slightly swept and almost straight trailing edge. The Type D and the larger, two-seat Type E were popularly known as the "Antiseptic" and the "Yellow Peril" because of the colour of the anti-corrosion paint on wings and tail.
The Type G used wings of the same plan though of unequal span. It was a three bay biplane having slight wing stagger, with two pairs of separate but wire braced interplane struts per wing. Only the upper wings carried ailerons, which were operated via king posts that appeared as extra interplane struts near the wingtips, but extending above the upper wing and carrying the control wires. The details of this arrangement were modified at least once. The slender fuselage was positioned between the wings with struts above and below. It was flat sided, with a curved decking behind the pilot who sat in the rear seat. An early photo shows a single cockpit opening, but later there were two separate open cockpits for passenger and pilot. The pilot's upward view was assisted by a small V-shaped trailing edge cutout. The horizontal stabiliser and fin were sharply swept at their leading edges. There were separate elevators and a rudder of half-heart shape, the point extending well below the fuselage to about the level of the lower wing.
In its early form the Type G had a two-wheeled single axle main undercarriage mounted by a pair of struts on each side, one forward to the engine bulkhead and one rearwards to the fuselage via the main spar. Initially the wheels were supplemented by a pair of skids to avoid nosing over, but these were later discarded.
