I’m guessing that AEHS members would rank their mechanical interests as aircraft engines first, aircraft themselves as second, and perhaps car/motorcycle/marine/tractor engines as third. As new books on aircraft engines are few and far between, I’d like to suggest our members take a look at the book Beast by Jade Gurss.
It is the fascinating story about the development of a clean-sheet, pushrod V8 engine built in secrecy in just 11 months, specifically for the 1994 Indianapolis 500. Why this engine at this time is an intriguing part of the story. The cast of characters include Paul Morgan, Mario Illien, the determined and fastidious wizards at Britain’s Ilmor Engineering Ltd., Roger Penske, Al Unser Jr., Emerson Fittipaldi, Mercedes-Benz, and the Indianapolis 500 monarchy. This is a fascinating mix of ego, genius, drive, and accomplishment.
The story of the Beast, the Ilmor 265E engine, reads very much like a wartime emergency development program. Every trick, technology, and supplier is chased and cajoled into producing miracles in hours or days instead of weeks or months, in complete secrecy, to exploit a unique window in competitive time.
The book is excellent story-telling that contains sufficient technical detail to satisfy engine lovers, an appropriate dose of open wheel racing history, and some interesting bits of aviation. The author insightfully and authoritatively develops the personalities of the engineers, mechanics, technicians, and designers of the engine as well as those in top management. Their personal recollections and insights are wonderful to read.
With excellent color photographs and outstanding technical drawings, I read the book in one very pleasant summer day. I highly recommend this outstanding book.

When we think of Napier the immortal Sabre immediately springs to mind. However, this long lived company has a rich history going back to 1808. Author Alan Vessey, who is also Secretary to the Napier Power Heritage Trust, has written other books on the products of Napier but never one that covers the company's entire 200 year history, as this one does. And what a history it is.
The fledgling company cut its teeth on products such as printing presses and precision weighing machines for coins. However, the real meat of the book, at least for aircraft engine enthusiasts, starts with WWI and the Napier Lion. All previous documentation has indicted that Rowledge, who later moved on to Rolls-Royce after a dispute, was responsible for the Lion's design. Although author Vessey credits Rowledge with much of the development most of the accolades go to Montague Napier for the Lion's design — this came as a surprise to this reviewer.
Napier was among the early manufacturers of luxury automobiles plus commercial trucks. These and Napier's other products of the period are well covered. Many land speed record cars were powered by Lions, the ultimate being the Railton Special driven by John Cobb to a world speed record in 1947, a record that held until the mid 1960s. Likewise, many water speed boats were powered by Lions. The dubious means by which Rolls-Royce captured control of the bankrupt Bentley is briefly covered. Reading between the lines one cannot help thinking what would have happened if Napier had been successful in their acquisition bid for Bentley … Schneider Trophy aircraft powered by Lions are also covered.
By the early 1930s we get into the Halford era whereby Frank Halford acted as a consultant and designed the Rapier, Dagger and Sabre. Having spent most (all?) of his career with Napier it is perhaps understandable, that the author did not go into great detail about the Sabre's woes and glossed over the assistance that Bristol gave (was forced to give?) for Sabre sleeve production. Development of a two stage, intercooled Sabre driving contra-rotating propellers was a fascinating insight as to where development was heading. Of course this did not happen; instead Rolls-Royce developed their version known as the Eagle 22.
Post war developments include the incredible Deltic two-stroke Diesel. Although never intended for aircraft propulsion it was built to aircraft standards with regard to precision and light weight. Non starters, such as the Nomad turbo compounded two-stroke aircraft Diesel, are also described. Entering the gas turbine field late in the game made it a tough chore for Napier to catch up even though the company produced some excellent engines. Reading between the lines it was apparent that after about the late 1950s a slow decline started. It was somewhat reminiscent of the decline of Wright Aeronautical. Finally in 1974 the name Napier disappeared and sadly these days few people have even heard of the name.
A few inevitable errors crept in such as describing George Eyston's Thunderbolt car as being powered by Merlins. In fact this land speed record car was powered by a pair of "R" engines. However, this should not put off a potential purchase; this book represents an excellent read and is highly recommended.

Most, if not all of us enamored with aircraft engines started our infatuation with model aircraft engines. If you want to take a walk down memory lane then this book is for you. I was delighted to see engines such as the E.D. Competition Special, my first engine, featured. Even though the Competition Special was a pretty awful engine it has the distinction getting me started with my passion. Engines from all over the world are covered, many of which I had never heard of and many more were, and still are in many cases, household names. All the major manufacturers are covered along with unique and one-offs. Each engine is featured with a photograph and brief caption. The book has no text, however, it would have been nice to see a more extensive write-up on the engines. Understandably, little information is available on the more obscure engines but engines such as the ETA 29 (a favorite of mine for Class B Team Racing) and other more common ones could have benefited from better descriptions. If you are nostalgic about the model engines you played with as a youngster then this book is a recommended buy.

Review by Jerry Wells
Charles Redrup enjoyed what most people would consider to be a very fortunate life. He was born in 1878 of wealthy parents who lived in South Wales, UK. Such was the availability of family money that all ten of the Redrup children (of which Charles was the first) were able to receive a good private education. Furthermore, at the age of just 16, Charles' parents bought him a house near the family home in the coastal town of Barry. Money was provided to set up a workshop (including a lathe) for the boy to foster his growing engineering interests and, on top of all this, he was signed up as a Premium Engineering Apprentice (i.e., the parents pay the employer for the instruction) with the Great Western Railway for a five year period.
From this beginning, Charles Redrup was able to pursue his love of engineering for the whole of his life and he did this mostly in England working sometimes for established firms and sometimes with a few private partners.
In his time, he designed rotary, radial, and axial engines for motorbikes, cars and aircraft. He started his married life in the aforementioned parental-gifted house and by 1925 Charles and Jessie Redrup had a family of eight.
Professor Fairney does his best to describe the huge variety of Redrup engines but struggles a bit. For instance, the first Redrup engine was a small, 2-cylinder rotary for motorcycle use (known as the "Barry" engine). The author provides a drawing, a photo and a written description of the device but there are major discrepancies between the drawing and the picture and the description doesn't do much to reconcile the two graphics. Fortunately, the patent (GB 1904 13314) can be easily downloaded from the Espacenet site to clarify the situation.
Redrup next turned his attention to engines for balloons and early aircraft. His first designs were described by him as "reactionless", i.e., the radial cylinders (sometimes with a propeller attached; sometimes without) rotated in the opposite direction to the crankshaft and propeller. The first "reactionless" was a 2-cylinder development of the "Barry" engine with push-pull propellers, the next, according to Fairney was "a contra-rotating radial aero-engine which had three cylinders and an epicyclic gearbox" but the photograph provided shows this to be a five cylinder motor with bevel gears (much like the Siemens-Halske rotary). The author then claims this engine was later converted by Redrup to operate with 2-blade contra-props and he shows a photo of such an engine (3-cylinders, 2-props) to illustrate this but by now the reader is totally confused!
Those interested in aero-engines are probably familiar with a couple of axial, air-cooled Redrup engines known as the "Fury 1" and "Fury 2" developed in the late 1920s. They didn't go into production but were flight-tested in Spartan aircraft. The full story is told in this book as is the saga of the Hart engine which was a 9-cylinder radial designed by Redrup in 1914. It showed some promise and was given some government encouragement regarding its further development. However, like so many of Redrup's designs, problems and delays ensured that it never went into production which was regrettable because Great Britain was chronically short of home-grown engines for its WW1 aircraft. Fairney claims that Redup filed a patent for this engine on behalf of the Hart Engine Company but no number is quoted by the author and there are no appropriate patents listed on the Espacenet data base.
This book is characterized by many "asides" and "potted histories", e.g., Redrup started making engines in his home town of Barry in Wales so a short expose of the coal exporting and brick manufacturing enterprises that made Barry a prosperous town is given. Similarly, brief accounts of the Royal Aircraft Factory, Crossley Motors and Bristol Tramways appear as background to Charles Redrup's association with them as his career unfolded. However, on the strength of his work for the A. V. Roe Company, the author devotes no fewer than 15 pages to yet another recounting of the R.A.F 617 Squadron "Dambusters" and their modified 'Lancaster' aircraft which seems a little excessive!
As a presentation this book has pluses and minuses. The text, on good quality glossy paper, is clear and easy to read although some minor imperfections indicate computer compositing. Illustrations abound—almost every page has a picture or diagram on it. In the middle of the book there are 24 pages of colour pictures, which look great. What spoils the graphics is the huge variation in the reproduction quality of the black&white photos. Far too many have a washed-out, faded look to them. The scanning and printing of original document pages is particularly bad—most are indecipherable studies in shades of gray. All this is just another indication of the fact that the book publishing industry and computers have a long way to go before they can be regarded as compatible.
For all his lifetime of tinkering with engines and other devices, it appears that Redrup never produced a motor or a device that could be classified as a "winner". Undoubtedly, he was a trier and an eternal optimist. His story is interesting and we are indebted to Professor Fariney for bringing it to us.

Written by one of our members, this book tells the story of the development of light aero engines, by the motorcycle company, Douglas, in the Bristol area, and further developments at Weir Pumps in Glasgow.
Introduction — a three page brief history of the Douglas Company, introduction to the motorcyclist and engineer, C. G. Pullin, who was the major figure in the development of these engines, and the move to Glasgow, where the development of the helicopter took place. An interesting point made (which struck me) is that an explanation is given to horsepower rating, then, and subsequently.
Forward — a one page statement from the great grandson of the founder of the Douglas Company.
Chapter 1: Wings For Twins — ten pages, describing the Under-Secretary for Air's 1923 incentive for the development of ultra-light aircraft, in the UK, known as the Lympne (Kent) Light Aircraft Competition. One page has a list of entrants and with one page of photographs, and each aircraft and engine used is described. Subsequent to this was the 1924 Rhon Glider & Light Aircraft Competition, and, again, one page lists the entrants, with a page of photographs.
Chapter 2: Flying Flywheels — Fourteen pages, including graphs, photographs, descriptions, installation drawings, (one page only) of the use of Douglas motorcycle engines in aviation to 1932. The specification pages give the facts and figures, including materials used. Finally, there is a one page chronology of the Douglas aero engine developments.
Chapter 3: Dark Clouds Over Bristol — Short four page chapter. Describes the takeover of Douglas, the start of work on an autogiro, and the move North to Glasgow. Also, the start of specifically designed aero engines.
Chapter 4: Designed To Fly — Sixteen pages, including seven pages of photographs, three pages of drawings, and three pages of specification, of the design of these new purpose built aero engines, to photographs being of aircraft fitted with these engines. One fault — the aircraft in the lower picture on page 56 is a Helmy Aerogypt, described later on in the book.
Chapter 5: Refinement By Proxy — Nineteen pages delving in a more technical manner into the Weir engines, with three and a half pages of photographs, three pages of engine specifications, and nine pages of technical drawings plus sections of the engines and their features, including a patent drawing for an oil cooler.
Chapter 6: Dreams Of Power — What Might Have Been. My favourite part of the book. Twenty-three pages, much as the previous chapter, with one and a half pages of photographs, a cutaway drawing of the Monarch engine, nine pages of technical illustrations, and six pages of specifications of engines planned for the future. Also describes what the company intended to do if they continued.
Chapter 7: Competition — describes, usually, on one page, the other engines that the Douglas/Weir engines were up against, mostly a half page photograph and half page specification, and some of the aircraft fitted with them. There are seventeen photographs in this chapter.
Chapter 8: The Airframes — Sixty-eight pages, forty eight photographs, brief specifications of forty-nine/fifty aircraft fitted with Douglas engines, and twenty-four pages of one-page three-views of some of the aircraft fitted with Douglas engines.
Chapter 9: Auxiliary Power Units — this section would have made an excellent article in Torque Meter (perhaps we could ask our colleague for permission to download this part to the members section of the website). Ten pages, describing generator sets, APUs, and aircraft pressurisation tests, using Douglas engines. The design of the four-cylinder starting engine for the R-R Eagle engine, if expanded, would also make an excellent article. Seven photographs, one small cutaway drawing, and two pages of sectioned drawings of this starter engine, in total.
Chapter 10: Survivors — Extant Engines and Airframes. Nine pages, containing thirteen photographs.
Appendices — three appendices, listing light aero engines produced by Douglas & Weir, data of aircraft fitted with these engines, and a glossary of terms throughout the book including some specifications of the materials used in the construction of the engines.
A one page bibliography, two pages of acknowledgements, and a seven page index complete the book.
Note: all photographs are printed on the pages, not glossy copies.
All in all, an excellent record, of this fascinating, aeronautical achievement. I intend donating a copy to Glasgow University library.
