Interestingly, if such a rotor with wings would also be more efficient than a traditional propeller for the ship. Maybe he wouldn't beat as much unproductive foam as the traditional one 🙂 You need to ask some Sailing Captain to check it 🙂 .. And maybe it would be a bit cheaper ..

About this 3 cylinder engine ANDREW,
See the top two cylinders have a scraper ring fitted but have only one oil control ring and only one compression ring fitted?
How is this?
Two stroke I take it?
Why two crank journals on the top picture?
Why not two conrods on the same journal?
Moving onto the biggest lower piston again one missing compression ring?
Where is the scraper ring?
There is none?
What’s the score here then re the piston thrust face with no lower scraper ring fitted?
Tramline jobby here then in the making?
Looks like if one were fitted at BDC it would stand outside the liner/ parent bore, is the bottom end got a large relief taper machined in it to simulate a piston ring clamp type situation for re entry purposes?
What’s with this “ windows speech ?” Do you mean ports?
Also digging into my toolbox right by my bearing scraper I remove my dividers ( the imperial ones, not those metric ones ) and see that by measuring that long stroke top end travel that the lower scraper ring will sit outside the bore at BDC?
Furthermore those Conrod’s appear to have no H section present?
So is this an H.P. I.P. L.P. Set up?
Also why is the R/H/S PISTON running behind the L/H one?
Carb or injected?
Giving the matter further in depth thoughts I can only conclude that that mm ( Mickey Mouse ) measurement system that you are forced to use at your Lat/Long has perhaps affected your complex calculations to such an extent that by converting to pounds shillings and pence ( ie Imperial ) could well save the day and prevent this engine from perhaps running the other way.
To that extent I would be more than willing to loan you my Imperial dividers by V L Churchill. ( of course )
They would, as such prove to you that beyond all reasonable doubt that N is indeed the unknown number and progress your advanced complex designs of which many of us out here struggle to take on board.
Opposed piston engine with a difference then?
Remembering The Good Old days, when Chiefs stood watches and all Torque settings were F.T.

Okay Marlyn, I see you've started to follow my engine closely .. That's good because that's the future of 4-stroke engines, but you have to find the right answers to a lot of new questions first. How many ? Well, I think that about 90 percent of the old knowledge needs to be thrown away and replaced with a new one .. many have aversion to it, because they feel that it is so .. and in addition, these units have to be converted into imperial ones .. You pointed out to me that I should also give in imperial ones, because you understand the matter well, and you want to help me spread the idea .. And here you are 100% right with these ones ..
Well, my prototype (the latter) was built on the basis of a two-cylinder engine with a total base of 600 cm ^ 3, i.e. 36.6 in ^ 3. The total capacity of this engine, including the capacity of the suction piston, is about 958 cm ^ 3, i.e. 58.5 in ^ 3 (but exact, depending on the position of the crankshafts) ... dimensions, made for racing with my system and will reach the power of 100 HP ... Meanwhile it turned out (in my life threat) that the engine has about 250 HP, both values ​​at 10,000 RPM. It was so far from my assumed parameters that it never occurred to me that the engine could have so much .. And I could not believe it myself .. Only my slow and rational analysis more or less replied that it is probable with such an engine. There are many things to it, and most importantly, this power gain does not come from an increase in revolutions, but only from an increased torque of the engine. Therefore, it is not surprising to other people that such parameters are impossible to obtain, since the same in I did not believe it, although I am a designer and constructor of this engine. But it turned out to be true. and for now there is no other way but to believe my words .. I have a working prototype, but I will not allow me to measure the power on an engine dynamometer, because I know that with such a measurement, the engine would roll immediately, because the bottom of the engine comes from the factory engine which has only .. 23 HP .. But I think that real experts on the basis of observation of the engine and measuring eg. the fuel nozzle in the carburetor, they will also be able to estimate, like me, the power of this engine at about 250 HP at 10,000 RPM. Probably it is also thanks to my honest way in this prototype, and for example I wanted to make smaller windows, but they came out bigger and I couldn't fix it anymore. The opening and closing angles of the "valves" (pistons) have reached 360 degrees of crankshaft rotation, so the engine only idles at 1000 RPM, but then it is amazing ...
Regarding rings, you can use any combination, but I used such a dykes ring.

http://mecoa.com/faq/rings/ringtypes.htm

The question about two crank pins is correct .. I applied a certain drawing trick to make it clear how the pins are arranged and how the connecting rods reach the individual pistons .. in nature it would be necessary to draw one piston after the other, which would prevent a good reading of this drawing and understanding the idea .. Besides, the pins are shifted by 90 degrees, because this is what the "timing" requires.
Yes, windows in my understanding mean ports ..
So the lower ring is outside the window and it must be so that the oil does not get to the window (port) ..
Thanks for understanding that N is a really unknown number .. :roll:

Well, at the end, this is the value of my work .. Take the best day's pay you have ever received, for being a good mechanic and multiply it by 1000 days .. 3 years that I spent only on the second prototype ..

I hope you follow my PhD thesis defense .. :D

Andrew :D
