Ader Avion III

The vein Éole III (also called Avion III or Aquilon ) was to develop an aircraft of the attempt by Clement Ader. The basis for the model of predecessor Avion II construction, the Avion III lasted from 1894 to 1897.

Construction

The Éole III had the shape of a giant bat, consisting of wood and canvas with a wingspan of almost 15 meters. Vein had not only the form but also the framework modeled on the skeleton of the animals. This construction, in other words the derivative of the art of biology is also referred to as biomimetics.

Served to drive two four-leaf propellers were driven by two very lightweight steam engine with 30 hp. The control of the flying machine was made possible by a rudder and movable wings that could change their curvature. However, the visibility for the pilot through the stem was severely restricted. The flight apparatus weighed ( without pilot ) just under 250 kg.

Flight Test

On October 14, 1897, the boilers were heated wire and stepped in front of an official Commission to prove that his flying machine actually can fly. However, it was artery due to its lack of knowledge of flight and the unstable attitude not to let the Avion III stand out over a longer distance. Only short air jumps, described by the Commission as hops were observed. Nevertheless, the Avion III, was an outstanding design and represents a milestone in the development of powered aircraft with engine power dar.

The Avion III is one of the permanent exhibits at the Musée des Arts et Métiers, a museum of scientific instruments and inventions in Paris.
