OCTOBER 23, 1909. FLYER SILHOUETTES FROM THE PARIS SALON. (Continued from page 652.) Dutheil-Chalmers. Biplane designed somewhat on Voisin lines, but remarkable for the prevalence of ,wire-susp_ended members. The pilot's seat is A feature in the design which is uncommon is that the outrigger for the tail springs from the front struts of the main planes instead of from the rear spars. This increases the length of an already long member, and thus adds to the difficulties of transportation when Dutheil-Chalmers Biplane at Paris Flight Show. hung on wires, as also is the steering-wheel, and the same system has been adopted for supporting the short spindles on which the balancing-planes between the main decks are mounted. This latter dismantled, but at the same time it affords a convenient support for the engine, and otherwise makes for straightforward construction. The chassis combines runners and wheels, the latter being spring detail is well illustrated in the accompanying photograph; the arrangement of wires there shown applies in the main to the other members which are less clearly visible. De Dion. Multiple-decked flyer defined by the makers as a " dix plan." In reality it properly belongs to the category of " five-deckers," since on either side of the centre body there are but five tiers of sup- porting surfaces. Each half deck, that is to say, each surface element on either side of the machine, is independently mounted on a longitudinal hinge, so that it can tilt out of the horizontal. All suspended. This portion of the machine reflects the source of the design, which we are informed originates from the makers of the A via monoplane. edges are horizontal, but this condition is disturbed in the event of loss of equilibrium, and the object of the De Dion system is to provide a means of maintaining the balance by the application of this principle, which is analogous to that of the dihedral angle in the Antoinette monoplane and to the description of which we would refer our readers for further reference to the subject. Four chain-driven propellers are fitted. In front of the machine is a biplane elevator, while behind is a biplane rudder intersected by DE-DION the decks are connected together, so that this tilting is reproduced simultaneously throughout, but in its present state the machine is unfinished in respect to the controlling mechanism. The object of thus pivoting the decks is to provide a means of balancing the machine by altering the " projected area" of the surfaces on either side. The air pressure on a plane is normal to its leading edge, and if the leading edge is not horizontal the vertical component of the pressure is reduced below the maximum. Normally, all the leading a horizontal fixed tail. The construction of the elevator outrigger resembles the Wright design.
