That looks a lot like the gearbox that failed, killing the pilot when the engine disengaged from the prop and he dead-sticked it into a hotel building. It was about a week after the alternative engine fly-in at Ed's place in Paduka, KY. As I recall, it was a Glasair III with a turbo-charged LS1. I have video of a ground run around here somewhere. Real sad story. Can anyone confirm whether or not it was the same make psru? I never read the final accident report.

I went back to the exhibit buildings, and took some photos of the psru’s offered by www.autopsrus.com . I will forward these later today as every thing gets transferred . They are spur gear drive, have there own oil supply and pump, use pressure fed roller bearings, will provide oil for a constant speed prop, and are available in many reduction ratios. They make a unit that can be straight through, suitable for the 13-B, the casing is CNC machined. They use a flywheel for the torque damping, and it has a centrifugal clutch that disengages the prop below ~900 engine rpm, so when starting there is no prop load. Will likely be heavier than Tracy’s

I have to reduce the size of the pictures before I can send them.

Tracy,

    That is very interesting! Could one be built specifically for my combination of a high HP 20 B? I would have more peace of mind knowing how it was put together by me along with your knowledge and experience. The thought of someone just starting out making them does not sit well with me as they are an unknown.

   Let me know what you think and I will be in touch.

Thanks for your time!

The design is royalty free. Anyone who wants to build it is more than welcome.   I can help with info if you need it.

Well, barring the passage of the “Affordable Airplane Act” perhaps we should start trying to solve our own problems.

I don’t know what the transaction was regarding production of Tracy’s design but if it’s based off of royalties for every unit sold, I would say that it’s not benefiting anyone.

Perhaps a competitive bid is in order?

Absent a viable PSRU solution, there probably is no, “rotary engine option”… :>(

…… no sign of rotaries.

What I have found is that if you want there to be a Rotary Engine forum, you have to do it yourself.

If I had a flying Rotary, I would be willing to do this but as I do not, it would not be appropriate.

We should make an effort to have a “Fly Rotary” forum and present our case for the Rotary Engine as a viable alternative to the piston solution.

I would propose that this comes from our group rather than as a piggy-back on to any of the other alternative engine groups.

I would not want for our engine solution to be sandwich between the Corvair, Subaru and Volkswagen groups.

If you want to see it there, you have to make it happen.
