Chazal

   Henry Chazal was involved in the construction of at least 4 aircraft and probably more, such as the Pacchiotti, a Gabardini, and the Marcay-Moonen; but it is difficult to say what exactly he contributed to the designs of such different machines.
   Only a single monoplane carried Chazal's name, in large letters on the fuselage, Chazal-Gourgas; it was called L'Aiglon. The wings were thin and curved, with inset ailerons; a large trapezoidal rudder was set between 2 elevators, and triangular tailplanes on each side were set at a high angle of attack. The undercarriage consisted of 2 wheels at the tip of a lozenge-shaped frame welded to a central horned skid and attached to the fuselage by numerous struts. A wheel on a column operated all the controls; a substantial pylon supported the wing cables. The engine was a 4-cylinder inline; the machine was tested at Issy in August 1911.
