L.Opdyke French Aeroplanes Before the Great War (Schiffer)
Deleted by request of (c)Schiffer Publishing
The other 4 designs were all 2-seat tandem-wing monoplanes; the high parasol rear wing was set close behind the high parasol front wing, at a lower angle of attack. All 4 had rear monoplane elevators and single rudders. The positions of the wings in these 4 designs moved further and further forward, the pilot always below the rear wing and the passenger/mechanic below and to the rear of the forward wing. Descriptions of Hayot's device remain unclear. The wings were mounted on frames which oscillated freely fore and aft on the sides of the fuselage to damp oscillations of the machine between 2 stable positions. It appears that the inventor was pleased with the lack of sensitivity of his controls, and that he continuously increased the power of his machines from 50 to 100 hp, at the same time reducing their weight.
(Data for the 1913 design under construction in 1914: span: 13 m; length: 8.65 m; wing area: 35 sqm; empty weight: 550 kg; 100 hp engine)

One of the machines of Louis Adolphe Hayot. Hayot was obsessed by the subject of automatic stability of aeroplanes, just as other designers in France. The military establishment was also very interested in automatic stability, probably because a stable reconnaisance plane could have a clearer vew of the proceedings on the ground (better pictures etc.).
Hayot obtained quite a lot of patents in France, Great Britain, Germany and Swiss on the aspect of stability of aeroplanes.
This double-monoplane construction was continually developed during 1912 - 1914.
