Hi folks,
Hope this isn't old news but seeing some threads on Papin and Rouilly's Gyroptère / Monocopter designs:
Publication number: US1133660 A; Publication date: March 30th 1915
Filing date: April 29, 1912; Inventors: Alphonse Papin, Didier Rouilly.
"The invention consists substantially in an improved helicopter in which the propulsion is effected by the reaction obtained from jets of air blown into the atmosphere through passage orifices or nozzles in the helicopter, on the principle of the aeolipile.
The improved helicopter has a single propeller or screw provided with one or more hollow blades or wings, at the ends of which the orifices of issue are located, the said screw carrying blower means adapted to impel air through the passages and orifices of the wings, and its boss adapted act as support for the helicopter when it is resting on the water or the ground."
