Very interesting. Thanks for sharing Dave.
I was making noise over your house this afternoon. Next time, I'll pick you up and we can fly down to Hanscom to pick up a few toroidal props to test. :) -- Q2 N86KL |

April 1 is right around the corner. But on a serious not, I may remember some of this circulating, pardon the pun, in Q-performance posts of the past, along with some other scimitar designs like those developed by a Lancair flier who used to frequent some of our Quickie West coast fly-ins, the Elippse propellor developed by Paul Lipps.

Phil,
I put Paul Lipps “Elippse” prop on my Quickie back in the day. It came off his Lancair for a test. It was a weird looking but fast prop. He made some pretty impressive numbers with the Phantom II Biplane in Reno. I tried to get Craig Catto to
make one for me but he wanted to much to do it.
Paul was one of a kind and a great individual. I got to know him well. He was the brain trust behind Klaus’ Lightspeed Ignitions.

Paul's son was intending to pick up where his father left off on this design. The intention behind the design appeared to make sense but what was the result, Jim? Numbers. What happened. I am not negative to the concepts. As do most M.E. (NOT D.E.) I live
in a more positive mindset toward aviation innovation. Most of the D.E. (certainly not all) I have had to work with definitely have ego issues mostly surrounds a degree of some kind. Some of what I wanted to investigate and never has been done yet might still
be worthy in investigating. Paul had results..of that there is no question.
I was also involved directly in the Wind Turbine powerplants over the Columbia River.. was part of the engineering team and my LLC was one of the foundation companies that raised the first five machines near Goldendale Washington along with Mariah Energy.
Now there are literally thousands of the larger units as we have also here in Oklahoma both in Washington and the Oregon river basin 800 or so feet below. We installed the first five on what was at one time the Boeing Mod 5 location. Take a goodlook at
the Turbine blades on todays machines and you'll see Pauls work also.

Dave, that looks interesting. There is a Seattle company that probably over twenty years ago had a winglet design that looked like half of one of those propellers. I have the article in my file. I would be interested in seeing a comparison in aviation like they did marine. John Hoxie God is good always. ALL WAYS.
