Witzig-Liore-Dutilleul

   WLD 1: The first WLD was shown in 1908, a fragile-looking biplane with overhung top wings, long uncovered nacelle ahead of the wings carrying a single forward elevator; a large floppy rectangular tailplane with 2 rectangular rudders fitted below it with 2 tailwheels attached. Between the tailplane and the top wing were set, at graded height and interval, 2 short horizontal panels the span of the tailplane; the aeroplane was supported on a tall undercarriage structure with 2 trailing wheels. By the time the wings were attached, the single forward elevator had been replaced by a biplane cell, and the landing gear legs and pivoting girders for the wheel supports had been changed, with the wheels forward instead of castering aft. But with this arrangement the whole structure sagged visibly.

   (Span: 8 m; length: 12 m; wing area: 50 sqm; weight: 550 kg; expected top speed: 15 km/second (this seems not to have been a misprint!); 50 hp Renault)

   It was subsequently modified further, with a heavier supporting box structure for the aft fuselage, and various combinations of the supplementary rear panels; the wheels once again were reversed, to trail aft.
