What is the name of the airplane engine where the crankshaft stays stationery and the crankshaft rotates?

Answer 1

The rotary engine is where the engine rotates around a fixed shaft... F4U, T6 Texan
Another option works like your car... a stationary engine which has pitsons attached to a shaft and as the fuel explodes in the chamber the piston moves causing the shaft to rotate and the shaft is directly or indirectly attached to the prop.

One more but using is similar property, is the the turbine shaft... which mean exactly was it says. The shaft is attached to a turbine...

Answer 2

Chris is correct.
The French built LeRhone engine had a stationary crankshaft, with the engine case/cylinders spinning, while the prop was attached to the front of the engine case.
Technology being what it was back then (or more correctly, what it WASN'T), they felt the cylinders spinning in the airstream would help cooling.
However, it also acted as a small gyro, meaning the aircraft banked in one direction MUCH more easier than the other direction.
Also, they were lubricated by castor oil, much of which blew out the engine (due to exposed valve trains, etc) and tended to be ingested by the pilot, which made the outhouse his first stop upon landing.
Finally, they had no throttle, so to slow down, the pilot would toggle the magneto off and on. The problem was, as the engine was still turning with the mag off, it was filling the cylinders with the air/fuel mixture. So, when the mag was toggled back on, there was a chance of blowing the cylinder right off the engine, giving the pilot a little MORE shrapnel to dodge.
To prove this, with an automatic transmission car, drive at 45 mph. Leave it in gear, turn off ignition and coast for a short bit. Turn key back on while still moving. Let me know if you still have a muffler left on the car when done.

Answer 3

You mean where the crankshaft stays still and the engine rotates?

They are Rotary engines, as used on the Sopwith Camel.

They have a characteristic sound, being all or nothing, when you hear a WWI plane that sounds like it's engine is running then cutting out it's one of these, they had no throttle, so you had to cut them off when you wanted less power. Must have been uncomfortable, but most of the pilots didn't live long enough to be really bothered by it.

Check out the link below on Wikipedia that describes them.

Answer 4

Yup they're rotary engines, usually 9 cylinders. It was too hard to set up an adjustable carburator to control engine speed, so it was set up that the electrical system would cut off power. You could have 3 cylinders, 6 cylinders or 9 cylinders firing or none at all. The weight of the engine acted like a really heavy flywheel and was great for going from level flight to verticle - the bad thing was it was so heavy, the torque exerted would cause the direction of steering to be 90 degrees off.
