Weiss 1909 Glider

  Jose Weiss was a French engineer and painter domiciled in England who, at the turn of the century, was fascinated by the challenge of flight. After several years of experiments carried out between 1902 and 1907, during which about two hundred models were made, he evolved his formula for automatic stability of a tailless monoplane with curved, swept-back wings. To prove his theories he constructed a full-size aeroplane, a single-seat glider based on one of his large models, incorporating the qualities of natural stability found in the shapes of birds which Weiss believed of fundamental importance in the design of man-carrying aircraft. His answer to the problem was demonstrated in the curvature of the wings, the section of which was thick at the roots, but which tapered outwards until the tips were flexible. The positive incidence at the fuselage was decreased until, at the tips, a negative incidence was produced by wash-out and by turning the trailing-edge upwards. Hinged elevators extended from the wing-roots to part of the way along the trailing-edge to provide experience with control surfaces. The glider was christened Olive after one of Weiss's daughters, and was tested at Amberley, Sussex, during 1909 by E. C. Gordon England, Graham Wood (shown in cockpit) and others. Successful flights as a glider led to the installation of a J. A.P. engine, succeeded by an Anzani. The machine was taken to Fambridge, Essex, for powered experiments there, but it failed to leave the ground.

Another artist - the Alsatian Jose Weiss, who was domiciled in England - showed heartening understanding of the properties of the aerofoil in this thickening bird-wing model glider, which he exhibited in 1905.
