3top,
Dave, you are doing a great job NOT "pushing" your project on this site!!
It gets pushed.
Perhaps it doesn't appear so because its a concept not a product.
Did you ever consider a counter rotating system alá S-69 or Kamov? If, why did you go for intermesh?
Yes. An attempt was made to evaluate all weird and wonderful concepts, and the intermeshing won out. From all that has been subsequently uncovered, my believe is even stronger that it is the best; for certain applications, of course. Hopefully, this belief comes from an objective perspective and not an acquired bias.
The Quasiturbine engine is intriguing, but for one person, just working on configuration related concerns give enough pleasure and pain.
