To complete ones education on the advantages of the rotary engine
one must study the history of the aircraft piston engine.

This is a very concise history of the the aircraft engine
you can download.

I found it interesting that later models of the R3350 turbo compound
engine gave up to 3000 hours of service in airline use.

Early non-turbo compound versions used in the B29 were lucky to get 100 hours.

I have a subscription to this organization.  It is called the Aircraft
Engine Historical Society and their journal is called Torque Meter.
 Many of the articles are quite interesting, well researched and written
and others are not much more than a listing of technical information.
 There is a lot on the history of the engines as well the design
considerations.  You may find some interesting and useful ideas.
