Heppner turbine

I am interested in gas turbine design by H.A.M. Heppner, a German exile in Great Britain after World War II. Any information will be appreciated. I have been unable to find a useful reference on the web.

Must admit, have never heard anyone mention him!
There is a small reference to him here:

Seems he was a gas-turbine engineer at Armstrong Siddeley, last heard of in Montreal!

Certified as insane in Great Britain, too, ha-ha-ha... But, he did produce a very interesting turbine design that had an integral fluid transmission, so that you could run things right off the output shaft. No reductor (or re-drive as it is sometimes known) necessary. Saves space, weight, complexity...

Hello Bruno, on this page there is a short mention of the turbine, almost on the bottom of the page.

Here are a few patents.

Thanks, Leo. I found the other references myself, lapidary as they are, but not the patents. I'll go have a look now.

Hi Bruno,

Well, apparently those contra rotating types were built at some time and they gave good compression ratio, Probably faded into obscurity due to their over complex nature!

Here is another weird design for you and Viv to drool over!

He mentions on one page, a quote from Tesla:

"Today´s scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality."

I reserve comment!
