I would suggest you do not limit your search to The Netherlands. As far as I know, Berny is not a usual Dutch abbreviation of Bernard and I suspect Mr. Konings may have taken his trade to France or the UK. Looking forward to some more clarification.

Jan, as you describe it Benny (instead of Hesham’s Berny) went from Spain to the Netherlands East Indies, then back to Spain to work at Koolhoven in Nevers (France).
Or did he work at Koolhoven in Nevers, then escaped to Spain from where he went to the Netherlands East Indies. To me its seems to be a more likely course of events and possibly dates it to early 1940, when the Germans invaded France.
This then raises the question about a Koolhoven branch in Nevers. Unfortunately I am away from my home library for some time and cannot check this in Wesselink’s Koolhoven book. So if anybody has further information on that Koolhoven branch, please inform us further

Why do you choose to trust a French newspaper to have the right spelling of a Dutch name when Dutch people themselves tell you it's wrong??

I have two sources that mention a Koolhoven assembly operation on the premises of a factory for agricultural machinery in Nevèrs, France:

- 'Koolhoven - Nederlandse vliegtuigbouwer in de schaduw van Fokker' by Theo Wesselink and Thijs Postma, Unieboek, 1981
- 'Frits Koolhoven en zijn vliegtuigproduktie' by Dik Top, Repro-Holland, 1996

Both sources mention 23 partially assembled F.K.58s that were shipped to Nevèrs for final assembly, a few of these were completed. Dirk Top mentions the engineer Van de Wetering as manager for the French Koolhoven plant.

I think the first book is the one Jos Heyman is referring to. Writer Dik Top of the second book received enough assistance from Jan den den Das for Jan to be specifically mentioned as cooperator on the title page of the book. Well done, Jan.

Berny/Benny Konings is not mentioned in either book. As Jos already mentioned, both 'Berny' and 'Benny' are abbreviations for Bernard in Dutch. 'Benny' is the one more commonly used, but I personally know of one Bernard who goes by the name Berny.

Hi,

Mr. Von Baumhauer,In 1913,he built a model of a helicopter with two counter-rotating rotors,the helicopter flew,
but it was not stable enough.

Nice find hesham!

This is a compound-helicopter derivative of Albert Gillis von Baumhauer's 'conventional' helicopter of 1924. An obvious difference - aside from the biplane wings, obviously - is the use of an inline main engine. The 1924 helicopter had a radial in this position. Part of the downfall of von Baumhauer's helicopter designs was that they required a second engine to drive the torque-eliminating tail rotor.

Another unbuilt von Baumhauer project was his early '30s Helicoptère-vliegtuig (Helicopter-aircraft) with which he hoped to test lifting rotors in both fast- and slow-speed flight. The Helicoptère-vliegtuig was originally to have contra-rotating rotors (a return to von Baumhauer's 1910 model helicopter) but seems - appropriate to your find - to have evolved into a compound helicopter concept.

BTW, the 1924 helicopter had a single, teetering main-rotor but proved a poor flier (capable of making only short hops). It was destroyed in a crash on 29 August 1930 but von Baumhauer was unharmed. He was less lucky on 18 March 1939. While in the US on behalf the Luchtvaartdienst, von Baumhauer was killed in the crash of the Boeing Stratoliner prototype.

For von Baumhauer's connections with other helicopter pioneers, see The Transmission of Helicopter Technology, 1920–1939: Exchanges with von Baumhauer by Alex de Voogt.


Alex de Voogt also delivered a paper, Helicopter History: The implications of the von Baumhauer at the 33rd European Rotorcraft Forum at Kazan in 2007.
