samerprod, those would be really great to see against each other. if you find anything like that, let us know. I have been thinking for some time about how to create a CAE tool to get quicker/easier answers for rough prototyping and then further refinement

Sorry for not reading the entire thread first, guys. Please disregard my last.

if no one offers to do it for you, the book at http://www89.pair.com/techinfo/MassFlow/ductbook.htm is more than worth the cost. it has all you need to calculate that.

Here's an idea that could kill two birds with one stone - build yourself a new home. You can get a taste of homebuilding at the lowest level by general contracting your own home. You can finance this easier. I have read that general contracting your own home can save you 10 to 30% off the...

HarveyGP, You are correct. Some posts have been dumped. Mine was one. There was no emotion in it. Just a thought I had regarding comparing recips and rotaries. I guess it didn't sound engineery enough. I'll have to go back to school and take the "sound engineery" communications course.

Disappointing lack of response to your good question. Please let me know if you have found anything on your question from other avenues. My interest is in the ever increasing BPR's, optimal fan rotational speeds, simplifying the core engine, reducing complexity like gearing and the possibility...

To tell the truth, I am interested only in the diesel cycle and not just heavy fuel because of the results of the DA42 crossing the Atlantic. That event, I believe, is a watershed event that means everything is different now. The fuel specifics of those Thielerts mean a different future for GA...

Ok it's time for me to ask this question: From my little bit of USPTO searching and from someone else in another unrelated forum who says he has searched, saved and studied hundreds of rotary engine related patents- well, it seems to me that the only hold anyone has of anything related to the...

jejtopgun, I am very interested in learning about the German company working on a diesel version. Thanks in advance for any info.

Can anyone start producing rotary engines, or would they likely have to be licensed by companies like Mazda, Wankel, Moller, or others? Are certain critical technologies are still under active patents by Wankel or Mazda or ...?
