FIRST EDITION. The first suggestion of the screw propeller and design for a helicopter. In this technical work on the Archimedes screw the mathematician Alexis Jean-Pierre Paucton (1732–1798) proposed for the first time the screw as a method of propelling ships, although it would be another seventy years before the first steam ship driven by a screw propeller, the SS Archimedes, was built. In a section entitled “Du Ptérophore ou nouveau volant” (pp. 181–214) Paucton investigates the aerodynamic possibilities of the screw and describes the principle of the helicopter. Paucton’s work was carefully studied by later aviation theorists.
