Some period reference works available free on Google Play

I've found some interesting period references on general construction and operation of WWI-era aircraft.  If you have a Google Play account, each of these is available as a free/public domain eBook download:

 

1.  "Rotary Engines" by The Office of the Chief of Air Corps, US War Department, August 1919

 

2.  "Aeroplane Structure" by Alfred John Sutton Pippard and and John Laurence, 1919

 

3.  "Aeroplane Construction and Assembly" by J. T. King and N. W. Leslie, 1918

 

Each of these has great detail (plus photos and illustrations) of the internal workings and structures of a representative sample of British and French airframes and engines.

Thnx for that!

Cheers for the heads-up!
