Engine and Related Home Pages
This section contains links to sites addressing alternative aircraft engines,
then general links to other engine sites. No endorsement is made for any
of these sites or their products.
I've made an attempt to split these into categories and sub-categories.
If you don't see exactly what you're looking for, search around a bit...I
may have put it under the wrong heading.
A compilation of potential aero engines can be found on Jack Ericson's
Horizontally-Opposed

These are engines that are purpose-built for aircraft use (but not certified),
Non-US engines, or conversion of non-automotive engines. I've also
lumped in general technical-data sites in this area

Engine Maintenance and Advice
There are a number of folks who answer questions on engines on various
mailing lists. Occasionally, they'll set up a web page of summaries
of their answers. I don't make any claims as to the accuracy of the

Engine Weights and Horsepower
The data for the certified engines came from Janes; the data on the auto-engine
conversions came from the company selling the conversion. Some folks have
reported different experiences, noteably certified engines that weigh more
than the values given here. Dirk Rackley's detailed list of certified engines,
for instance, gives different weights. His list follows this one.
For auto-engine buffs, you can get a nice list of car-engine weights
at Dave
Williams' Engine Weights FYI page.

Structural Efficiencies
Paul Lamar assembled this list to compare the overall structural efficiencies
of various aircraft. He originally sorted the list by the ratio of the
empty weight divided by the gross weight. I prefer ratios where "higher
is better", so I have calculated the "Payload Percentage": The ratio of
useful load vs. gross weight. The higher the percentage, the more efficient
your aircraft is.

Some Books on Engines
Courtesy of Paul Lamar:
-
A History of Aircraft Piston Engines, published by Sunflower University
Press Inc. 1531 Yuma, Manhattan, Kansas 66502-4228. This is a reprint of
a book originally published by McGraw Hill in 1981. There are 250 pages,
sized 8.5 by 11 inches. There are many tables listing every engine ever
put in an airplane with all important specifications including weight.
There are many photos and drawings of all types of aircraft engines.
-
Schneider Trophy Racers by Robert S. Hirsch. Motorbooks International
Osceola WI. Excellent history of the water cooled V12 leading up to the
Merlin. Lots of good drawings done by the author and photos.
-
Sky Ranch Engineering Manual by John Schwaner This book presents
an excellent overview of the problems of aircraft engines. It is 500 pages
and a bargain at only $23. There are many details on the materials and
processes used to build a successful aircraft engine. There is a very good
and exhaustive discussion of destructive torsional vibrations and fatigue.
The telephone number to buy this book is (916) 421 7672. John is highly
thought of in the experimental aircraft community. [Ron W's Note: I'll
second the recommendation for this book...]
-
The Internal Combustion Engine in Theory and Practice, two volumes
by Charles Fayette Taylor. For those of you with an engineering degree
or equivalent, this series is the best there is. The MIT Press Cambridge
Massachusetts, and London England. AutoBooks in Burbank CA.
-
Volume 1: Thermodynamics, Fluid Flow, Performance. Second Edition
Revised.
-
Volume 2: Combustion, Fuels, Materials, Design. Revised
-
Introduction to the Study of Aircraft Vibration and Flutter by Robert
H. Scanlan & Robert Rosenbaum, Dover Publications touches on crankshaft
design. Lib Cong 68-22341.
-
Photo-Elastic Analysis by A. W. Hendry, Pergamon Press. Investigates
stress concentrations in complex machine parts such as crankshafts and
connecting rods. L of C # 65-29062. Only recently has computer finite element
analyses developed to the point of perhaps doing a better job on crankshafts
than these techniques invented in the 30's. The book has a great bibliography
on the subject.
-
Rotary Engine by Kenichi Yamamoto, published by Toyo Kogyo Co. Ltd.
(Mazda) in 1969. The definitive book on the rotary. This is a highly technical
book chronicling the development of the wankel by Mazda. Kenichi is an
engineer and has risen to be CEO of Mazda.
-
The Wankel RC Engine Design and Performance by R. F. Ansdale. Published
by A. S. Barnes & Company, L of C 69-18692. This book will be easier
to find then the Toyo Kogyo book.
-
The development of Piston Aero Engines by Bill Gunston, 1993, 1994,
1995. ISBN 1 85260 385 2. Patrick Stevens Limited/Haynes Publishing Sparkford
Nr Yeovil, Somerset, BA227JJ. Hard bound 213 pages. $39.95 at the Wright
Pat Airforce Museum. The first half of the book is on basic principles
and engine design. For the most part this is very well done for the non-physicist/non-engineer
reader. The middle is a history of of the development of aircraft engines.
The last chapter; "Chapter 8 Piston Engines Today and Tomorrow" categorizes
engines by air cooled, liquid cooled, diesels and unconventional. All engines
are included world wide no matter how obscure, starting with low power
engines for ultra-lights through auto engine conversions. The major fault
with this chapter is all engines are listed from PR information regardless
if they have run or even flown for that matter. Lamar's final assessment
of this book: "I think Bill Gunston is a little gullible. Other than that
the book seems to be excellent."
-
Allied Aircraft Piston Engines of World War II by Grame White, 1995.
Published by the Society of Automotive Engineers, Inc. 400 Commonwealth
Drive Warrendale PA 15096-0001 (412) 7765 4841 Fax (412) 776 5760 8.5"
by 11" hard bound 400 pages. ISBN 1-56091- 655-9. Lots of good drawing,
excellent cutaways and illustrations as well as photographs. Lamar's comment:
"Surprisingly not too technical despite the publisher. This is a well researched
book but rather disappointing to me as I would like to see a lot more technical
information about power curves verses BFSC, TBO's and such. I expected
more technical information from the SAE."

The Two-Stroke Cycle Engine : Its Development, Operation, and Design
by John B. Heywood, Eran Sher, Society of Automotive Engineers Summarizing
the dispersed literature on the two-stroke cycle form of the internal combustion
engine used in everything from chainsaws and motorcycles to marine propulsions
and power generation, Heywood (mechanical engineering, Massachusetts Institute
of Technology) and Sher (mechanical engineering, Ben-Gurion U.) overview
the principles, operating characteristics, applications, and history of
this widely-used engine concept. They evaluate types of models (gasoline
as well as diesel-fueled); review the experimental methods used in development
and testing; and address design issues. Illustrated coverage also includes:
mathematical models of the scavenging process, combustion, emissions formation
and control, and lubrication and wear. (Book News).
