Airplanes, Airships, Aircraft Engines

This book has been prepared with the idea in view of furnishing a good practical knowledge of aircraft to the Naval Service. The nomenclature contained herein was compiled by the National Advisory Committee on Aeronautics, which is without question the best authority on the subject in this country. The writer is indebted to the above committee for the courtesy extended him in authorizing its publication in this book. The writer is also indebted to Lieutenant J. W. Iseman, U.S.N.R.F., and Ensign J. C. Eames, U.S.N. R.F., for valuable assistance rendered in preparation of data on instruments and aircraft engines.
