Rudolph Kosch

Jump to: navigation, search

Rudolph Kosch was an aero inventor in Cleveland who designed a vessel with adjustable propeller for use as helicopter and airplane.

Léopold Desmarest lectured on Kosch to the Société Française de Navigation Aérienne, at a session held on 16 July 1896. Desmarest reported that Kosch had by August 1895 created a velocipede-like human-powered version of his helicopter aircraft, with slightly conical (nearly flat) blades. The writeup compares Kosch's vessel to one designed by Ponton d'Amécourt, a former president of the Society.[1]

It's not apparently in Brockett, 1910, but this publication is by Kosch: Latest Inventions in Aerial Navigation, Scientific American, May 30, 1896. We'll launch a page: Kosch, 1896, Latest inventions in aerial navigation. It's described here in the Review of the Engineering Press, in entry #6280: [1] thus: “Illustrated description of a new experimental machine, designed by the the author, and some results attained by it, with general remarks upon aviation. Sci Am Supplement, May 30 1896, 2800 words"

This work lists several patents, not all of which are in our records:

  • French 255717, Aerial propeller
  • German 89860, Combined screw propeller and aeroplane
  • British 1896-9129
  • He does not seem to have a US patent on his aeronautic invention; not clear why
