IftlGHT JULY 20, 1912. THE BREGUET BIPLANE. THOSE who attended the flying at the London Aerodrome on Saturday last were treated to a splendid display by Moineau on a machine that is relatively an uncommon one in England—a Breguet. This particular biplane is furnished with a 14-cylinder 100-h.p. Gnome, and drives two two-bladed propellers—virtually a four- bladed one—through pinion reducing gear. As it is the machine that will probably represent the Breguet firm in the forthcoming military trials a brief description will not be amiss. The photographs we publish give some idea of its appearance; the frontispiece this week shows the machine flying with Moineau as its pilot. In its design, the greatest ingenuity has been displayed in establishing a machine that will be to a great extent automatically stable, easy to control and transport from place to place, speedy and strong, that will lift much weight, and that will afford the pilot a large degree of safety. All these desiderata, and many more that, perhaps, are not so important as the above, M. Louis Breguet has provided for in the biplane that bears his name. 6 In the first place, it is a tractor biplane, and for that the pilot may reassure himself with the thought that a lot has to " go " before any of the effects of an assumed smash reach him, that is, if he is suitably strapped to his seat. Again, this system of construction lends itself extremely well to facility of dismantling. A most noticeable point about the cam planes is the small number of vertical struts employed in bracing them. Only four very stout ones are used, and they are arranged in a single rack. In this present machine two extra struts are used to support the top plane extensions. The planes themselves are built about a single tubular spar of steel disposed at the average centre of pressure of the surface—about one-third of the chord from "Flight" Copyright.
