FLYER SILHOUETTES FROM THE PARIS SALON.
Small monoplane, peculiar for the arrangement of the pilot's seat on a kind of toboggan-like structure mounted under the wings. The system is sufficiently self-evident from our general view of the machine. The engine, it will be noticed, is mounted above the wings, but is supported on uprights direct by the chassis; and drives a two-bladed tractor screw.
An interesting mechanical detail introduced by the makers, and placed on the market by them as an accessory, is a combination steering and controlling mechanism, designed on the principle of concentric spherical cages, each of which is a universal joint. The construction is approximately represented by the accompanying sketch. The device enables the steering column to be rotated or tilted either separately or simultaneously, according as it is required to operate one member or two at the same time.
Attention should also be drawn in the Avia flyer to the construction of wheels and ski on the chassis. The system is illustrated by our photograph of the complete machine.
The supplementary surfaces on the machine include an elevator and a rudder, both situated at the rear. Provision is also made for warping the wings.
