Thuau

   Victor Thuau was a former bicycle racer who turned to aeroplane design with little talent and little luck. He had built models before his only full-scale machine, a Demoiselle-based monoplane he called the Heroclite Phenomenon. The short rectangular wings were basically loose sails, each with 8 ribs and a leading edge; the tip of the leading edge was braced with a long spar running diagonally back to the aft fuselage, and the outer triangles of the sails worked as ailerons. The tailplane was deeply arched, apparently to increase lift at the tail. The fuselage frame was wide and squat, with the 10 hp V2 Anzani level with the top longerons; power was increased with the substitution of a 28 hp 3-cyIinder Anzani. A different propeller of Thuau's own design was fitted to each engine, one of them with adjustable pitch. The whole ugly little machine weighed 120 kg; it was tested unsuccessfully at Issy in July 1910.
