A.Andrews. The Flying Machine: Its Evolution through the Ages (Putnam)


Contemporarily with Mozhaiski the very accomplished French electrical engineer Clement Ader, who had acquired an early fortune from developing telephone equipment but had a private passion for aeronautics, began to construct a powered aeroplane. He chose steam as his medium, and designed a very efficient light engine. He installed this in a striking bat-winged monoplane, which he named Eole, and personally piloted it in a historic test at Armainvilliers in 1890. Witnesses said that it took off from level ground and was airborne for some 50m, but not even Ader then claimed that this very creditable powered take-off was a sustained flight. Sixteen years later he alleged that he had made a further flight of 100m in Eole in 1891, but this claim has been authoritatively refuted.

A very advanced light steam engine developing some 20hp drove Clement Ader’s eerie bat-winged Eole, which took off from level ground in 1890 with Ader fussing over complicated controls that were intended to reproduce many of the movements of the bat’s wing except actual flapping. Airborne for only 50m, and as blind as a bat because he had placed the pilot’s seat behind a tall boiler, Ader had no time to test these mechanical aids.

Clement Ader's own sketch of his Eole of 1890 shows its bat-like wings, feather-bladed single propeller and the caterpillar-track undercarriage that the inventor considered fitting instead of wheels. The fan-like protrusion on top of the fuselage is the radiator for its 20hp steam engine.

Clement Ader's Eole; the complex controls and bird-like structure show clearly in this single-propeller machine. (From drawings in Octave Progress in Flying Machines)
