How a Rotary Engine Works

http://www.mekanizmalar.com/rotary_engine.html
In the rotary engine instead of having a fixed cylinder block with rotating crankshaft as with a conventional radial engine, the crankshaft remains stationary and the entire cylinder block rotates around it

yes mekanizmaler. Lot of people doesn't know the difference between a rotary and a radial. The radial evoluted from this rotary. There was also a bi-rotary having a bit of both, likeThe Siemens-Halske, best air-fighter at that time.

And there is mine : watch?v=1ZqCdNU8MlA

@frankydevaere Thank you for your comment and nice video.

The only way that would work is if you spin the plane.  you will need many puke bags.

@UpcomingJedi These engines has been used in WWI and they are not my imagination.

thats radial not rotary

[mekanizmalar]

@hqfifty It is rotary NOT a radial. I am surprised that so many people does not know about this engine.

[mekanizmalar]

@Superchickenman159 NO this is a rotary engine. Please do a google search "Radial Versus the Rotary Engine" to compare these two engines. You are not the only one who confuses these two almost identical looking engines. While their looks identical, their operations are completely different.

So aside, from the fact that the rotation meant the engine didn't vibrate the airframe to pieces, or made it too heavy for a fighter aircraft, watercooling wasn't needed and the power-to-weight ratio was superior to the other designs at the time.

Later progress, meant the radial overtook the rotary concept (which died out with WW1).

Btw, not even in WW1, were all engine rotary. The most common type in Allied planes was a liquid cooled V8 (the Hispano-Suiza V8)

@UpcomingJedi

You're not funny.

Guess what. The crankshaft was fixed to the airframe.So what happens if the crankshaft is fixed? That's right, the crankcase (along with the cylinders) rotate. The propeller was bolted to the crankcase.

Why did they do this? Simple in WW1,engines still had serious cooling problems and in order to combat the serious vibrations of the other early engines they had to use a seriously huge and heavy crank,thus making the engine both slow and too heavy

@UpcomingJedi

Worked perfectly fine in WW1. Look up the Bentley rotary which powered the Sopwith Camel. The French Gnome Monosoupape or the German Oberursel. All used in WW1.

So what does this prove?

Well either you made a bad joke, or you really are as stupid as your name suggests. Next time you may actually use the internet to find info on (since it's all free there and requires very little effort) before thinking you know something.

@MiniWMDinc Ok, I see how that works. A seperate shaft on which this spins ... gotcha.

@MiniWMDinc

[MiniWMDinc]

these engines r real I'm doing a report on planes of ww1 and it wouldn't spin the plane

[UpcomingJedi]

@mekanizmalar They were used ... on what? All the air planes I have ever seen have radial engines where the crankshaft in the middle moves and the cylinders do not.

Rotaries like these have no reciprokating pistons! The only accelerative/decelative forces the pistons experience are turning somewhat faster during inlet/compression and somewhat slower during explosion/exhaust strokes. They just turn around without going up or down.
