If the engine spins with the propellor, then it is a • rotary engine, and it
is correct, see this link for more detail,

http://www.theaerodrome.com/aircraft/gbritain/sopwith/camel.html • .

In reality, the rotary engine packed so much torque • that inexperience pilots

compensate for it, and used the torque to their • advantage, amking the Camel
extremely manueverable. Often, a pilot would turn 240 • degrees one way to
make a 120 degree turn the other way, there was that • much torque.

There was a discussion about rotary and radial engines • in lugnet.military
not too long ago.

  I've been trying to find a diagram of the old rotary • engine,

  Anyone have any good information/references?

Try "radial engine" or "radial rotary engine"
the more correct term for the engine type in
your search.

I have two great books I found at Borders Books a few weeks
ago.  They are the "Illustrated Encyclopedia of Military
Aircraft" and  "Illustrated Encyclopedia of Civil Aircraft"
both by Enzo Angelucci.  Between these two books they have
most every fixed wing craft ever built.  In the first book
a number of engines are highlighted.  The Gnome Monosoupape
100 hp, Clerget 9B and Le Rhone 110 hp, are three examples
of rotary engines used by the Allied powers. All three were
developed in France.  I found this website
http://www.keveney.com/gnome.html  using the first engine
on the net.  Hopefully this helps!

(...) It sure does--thanks to all. I just needed a graphic explanation of how the engine stroked. :) I've always passed Angelucci up, only because he goes for breadth over depth. But for comparative discussion that's more valuable, no doubt about (...) (23 years ago, 20-Nov-01, to lugnet.build.sculpture, lugnet.build.military)
