George and Jobling Biplane

   The George and Jobling Biplane was designed by A. E. George and was built by George and Jobling at Newcastle in 1910. The machine was a single-seat pusher with a four-cylinder 60 h.p. Green engine which drove a 9 ft. propeller mounted on a fixed shaft above the engine, to which it was chain-geared. Exhibited at the Olympia Aero Show of 1910, other unusual features embodied in the design were the hollow struts and spars, balancers for lateral control mounted mid-way between the wing-tips and the sharp angle at which the skids on the undercarriage and wings were mounted to enable the aeroplane to clear ditches and other obstructions on the ground. Control surfaces comprised a forward elevator, mid-gap Curtiss-type ailerons and a single rudder mounted below a fixed tailplane. The machine made several successful flights at Gosforth during the summer of 1910. Span, 30 ft. Length, 31 ft. Wing area, 325 sq. ft. Weight empty, 662 lb. Weight loaded, 862 lb. Maximum speed, 48 m.p.h.

G. and J.

   BRITISH-BUILT biplane of 30 ft. span, the supporting surface of the main planes being 325 sq. ft., while the total surface, including tail, elevator and ailerons, is 438 sq. ft. A feature of this machine is the triplicate control, whereby both rudder, elevator and ailerons can be operated by one hand without any one motion interfering with any other. The rear tips of the top plane are extended and flexible, and coupled to the ailerons, so that lateral stability is governed both by the entering edge of the aileron and the trailing edge of the flexible tips.

   BIPLANE designed by A. E. George and principally remarkable for the fact that all the struts and spars are hollow. The outriggers that carry the elevator and tail are made of bamboo. A curious form of combination wheel and ski chassis has been adopted, the skis being wholly in front of the wheels and normally inclined upwards; their object is mainly to assist the machine over holes and small ditches. A very interesting feature of the machine is the method of mounting the single chain-driven propeller upon a stationary axle, which is held by adjustable tubular steel struts upon the engine bearers. This stationary axle lies immediately above the engine, and the mounting of the propeller is thus entirely independent of the framework of the machine.

WING SECTIONS. - The above diagrams afford an interesting comparison of the wing sections of aeroplanes exhibited at Olympia. They are all drawn to a common scale, but have been set at an arbitrary angle of incidence, which does not necessarily represent that of the aeroplane In actual flight.
