Windham Biplane
  
   Captain W. G. Windham's pusher biplane is depicted at the 1909 Olympia Aero Show, and was constructed for him in France by Pischoff-Koechlin. The machine embodied a number of his own design features and was modified after the Aero Show by the lengthening of the nose and the tail booms to improve stability. The four-wheel undercarriage was augmented by the addition of a single wheel at each wing-tip, and a single rudder was fitted aft within the fixed biplane tail. Twin propellers were driven by a twin-cylinder 35 h.p. Dutheil-Chalmers engine; in further examples of the biplane, intended to be built in Britain, a four-cylinder engine was scheduled to be used.

THE FIRST PARIS AERONAUTICAL SALON.

"Lejune (No. 1)."

   Biplane constructed by Messrs. Pischoff and Koechlin, of Billancourt, for M. Lejune. It is a feeble looking job in bamboo and unvarnished linen, but is designed a little after the lines of the Wright machine in general appearance, although the controlling planes are quite different. There are two double elevators in front, situate some way apart, and a simple vertical rudder behind enclosed in a boxkite tail a la Voisin. The whole apparatus only weighs 150 kilogs., and is equipped with but a 12-h.p. 3-cyl. Buchet engine. The Wright system of chain transmission with twin propellers is used.

FLYERS AT OLYMPIA.

Pischoff (CAPT. WINDHAM).

   Capt. Windham, who has entered the commercial side of aviation, shows a biplane, which was constructed for him by Messrs. Pischoff, in France, embodying ideas of his own. Capt. Windham has now arranged to build similar machines in England for sale to the public at the price of L650 complete. One of the most characteristic features of the machine is that derived from the appearance of the outrigger framework which carries the biplane elevator in front and the rigid biplane tail behind. The first impression is that this framework is one complete elliptical unit, but closer inspection shows the lack of continuity in the upper girder members which stop short under the main planes. The machine is mainly constructed of wood, but has a certain amount of tubular steel work in connection with the chassis and the brackets for the support of the two chain-driven propellers which are situated immediately behind the main planes, and therefore a little aft of the centre of the machine as a whole. The planes themselves are double surfaced, but the appearance of the end webs does not give evidence of any close attention to special curvature. The decks are separated by vertical wood struts, with the usual system of diagonal wiring. The struts are bolted to strip iron angle plates, which in turn are either bolted or screwed to the main spars, but although this detail in the construction is evidently not intended to be flexible, the rough fitting certainly belies rigidity; in fact, there is a distinct lack of refined workmanship in many parts of the machine.
   An original feature of the control is pivoting the back of the pilot's seat so that by swaying his body he can operate the movements of a pair of small righting planes which are pivoted midway between the main planes at each extremity. The elevator and rudder, the latter being in the middle of the tail, are controlled by a single lever operated by the driver's right hand. The engine with which the machine is at present equipped is a 2-cyl. Dutheil-Chalmers, but the machines which Captain Windham will construct in this country will have 4-cyl. engines of the same make.

Windham biplane No.l was originally built by de Pischoff and Koechlin in France but was much modified later by Windham. It was shown at Olympia in March 1909.

A curious feature of the propeller on the Pischoff biplane is the lip formed on the periphery of the blade, which thereby somewhat resembles a big wooden spoon.

The Pischoff biplane is a tailed machine, and as such therefore belongs to the Voisin type, but it differs from the typical Voisin flyer both in appearance and construction. Its tail is not quite as far to the rear, and has a different normal level.
