The propeller motorcycle (also Aéromotocyclette ) by Ernest Archdeacon was an experimental motorcycle, the behavior has been studied by propellers at different speeds. Archdeacon designed and tested the motorcycle in 1906 in collaboration with Alessandro Anzani . The experiments also served to develop aircraft engines .

History and technology

The air-cooled V-engine built by Buchet with a displacement of 726 cm³ developed about 6  HP at 1800 rpm and was built into a bicycle frame so that the crankshaft in the direction of travel could directly drive the pulley of the propeller shaft via a drive belt. At the end of the approximately 1.5 m long shaft was a two-bladed propeller made of aluminum with a diameter of 1.45 m. At maximum engine speed, the propeller reached a speed of 900 to 1100 rpm. On September 12, 1906, test drives with the 70 kg device were carried out on a cordoned-off stretch of road near Achères . Alessandro Anzani is said to have driven a 1 km long route in 45.4 seconds with the extraordinary vehicle, which corresponds to a speed of 79.3 km / h. Anzani then became interested in aviation. In his company, Anzani Moteurs d'Aviation, he developed a three-cylinder engine (W3) which, as an aircraft engine, powered the Blériot XI in 1909 , with which Louis Blériot was the first to fly over the English Channel .
