The unbuilt helicopter projects of Hans Berger
« on: May 11, 2010, 04:14:07 am »
Hi,

from Wikipedia;
http://en.wikipedia.org/wiki/Hans_Berger_(aircraft_manufacturer)

Hans Berger was a Swiss inventor noted for the two successful helicopters that he designed and built by himself with no formal aeronautical training: the BX-50 of 1961 and the BX-110 of 1974. The latter design proved sound enough to earn a certificate of airworthiness from the Swiss Board of Aviation. Besides these two machines, Berger's other inventions were a jet-powered car, and numerous other helicopter designs. Professionally, Berger was the sales representative for Brantly in Switzerland and Liechtenstein.

Unbuilt helicopter projects included:
Berger HB-25 - 4 seat design with turbine power.
Berger BX-111 - 2 seat design with Wankel-type engine and coaxial rotors.
Berger BX-200 - 2 seat design with turbine power.
Berger BX-300 - 3 seat design with stub wings, to be powered by Turboméca turbine.

Why the heck can't I make a link that takes you directly to the article?  ???
To the heroism of the Resistance Fighters -- past, present and future -- this post is respectfully dedicated.

I suppose you could alternatively classify the BX-50 as an 'ultra-light' helicopter.  :)
