Charles-Edouard Guillaume and Swedish turbojet designs of the 1930s

[sienar]

Guillaume is probably a name familiar to some here, but not for many aviation related endeavors.
Nor are the Swedes known for turbojets.
However, I've found the following quote from the famous Von O'hain, when describing his experience filling a patent for his novel engine:

"The patent attorney found a jet engine patent by A. Lysholm(of Swedish company Milo Acticbolget) Sweden had a large number of proposals for beautiful gas turbines and turbojets using radial flow compressors. They looked very good to us, but these were patents on paper. No actual work had been done on these ideas. Actually turbojet patents of the Frenchman Guillaume should have been the cause for the rejection of practically all further turbojet patents"

He goes on to state that the German patent office didn't find that frenchmans patent, nor did the English office, which in ohains opinion granted farm broader rights to whittle then he believed should have been.

So does anyone have further information on any of these designs them what can be found through a patent search? I am especially interested in the Swedish designs, which based on his wording leads me to believe that he was aware of them while working on his own designs in the 30s. And if ohain was aware of these designs, then maybe the RLM and by extension jers and BMW were as well.

This is the first I have ever heard of sophisticated turbojet designs from Sweden and Guillaume. Any further info is much appreciated!

The French patent seems to be by Maxime Guillaume from 1921 but the Espacenet doesn't want to play ball. Image from wikipedia.

Sounds interesting, wonder what military planes would have achieved with that.

In 1906, the Swedish brothers Birger and Fredrick Lungstrom invented a radial flow steam turbine engine. The engine core contained two discs with circles of axial blades/buckets. The two discs counter-rotated, so each row/circle served as inlet guide vanes for the next outer row of blades/buckets.
Steam flowed outwards/radially.
Blades were axial … parallel to the drive shaft.
Lungstrom turbines were primarily used to generate electricity. Eventually Swedes were bought out by Brown-Boverie who built the first electric-generating turbine in Switzerland.

A few Lungdstrom turbines powered steam ships, but by the 1940s, they were superceeded by axial flow steam turbines.

The Sagita Sherpa light helicopter company is developing a Lungstrom turbine to power counter-rotating blades. We hope that modern materials and manufacturing techniques will revive Lungstrom turbines. The turbine is mounted half-way up the main rotor mast with the top disc turning the top rotor and the bottom disc turning the bottom rotor in the opposite direction. Since each rotor is directly driven by a turbine disc, there is no need for a main transmission. WE wonder how fast those disc will spin????

The basic concept has already been proven on an ultra-light (Nagano) Japanese helicopter with piston engines between the two rotor discs. The GEN H-4 has 4 X 10 hp. engines sandwiched between its rotor discs for a total of 40 horsepower. Gross weight is only 220 kg. It was introduced to the American market in 2001, but production was suspended in 2012 because of slow sales.

What was it ?.
