This book has nearly everything a propulsion book ought to have. It covers visionaries, inventors and manufacturers that developed and produced modern propellers, and explores the propeller's impact upon the world.
Kinney introduces us to Frank W. Caldwell, who as the civilian head of the U.S. Army Air Service Engineering Division Propeller Unit, shaped the future of American propeller development. Caldwell's WWI experience had convinced him that wood was not a suitable material for increasingly higher aircraft power and speed. Under his leadership, the world's first dedicated propeller whirl testing facility was built at McCook Field, near Dayton, Ohio. Here, propeller specialists could spin large propellers to destruction at speeds far higher than they would ever see in service. This promoted the investigation of propeller materials, construction and mechanisms.
The NACA conducted civilian propeller research. William F. Durand and Everett P. Leslie at Stanford University, and Fred E. Weick at the Langley Memorial Aeronautical Laboratory developed theoretical propeller performance models that were correlated to wind tunnel test data. NACA opened its full size Propeller Research Tunnel at Langley in 1927 under Weick's direction. In addition to its important role in verifying propeller theory, the Propeller Tunnel also facilitated development of the NACA cowling and the integration of the propeller, cowling and nacelle into aircraft wings and fuselages.
Propeller construction evolved from fixed-pitch to ground-adjustable to variable-pitch to constant speed. Materials evolved from wood to solid aluminum to hollow steel, and finally, in the 21st century, to carbon fiber/Kevlar composites. Each of these had its promoters and detractors. Kinney covers the people and major U.S. (Hamilton Standard, Curtiss Electric, Aeroproducts), British (de Havilland, Rotol) and German (VDM) companies that supplied large propellers.
Kinney also explores the surprising reluctance of the American and British aircraft industries to embrace variable-pitch and constant-speed propellers, primarily due to concern over increased weight and complexity. The tide turned in the U.S. when aircraft capable of coast-to-coast air service needed to operate from high-altitude airports and continue to climb if one engine failed; this led to nearly universal adoption of constant-speed propellers for U.S. airlines in the mid-1930s. The British were much slower to install constant-speed propellers, and only after witnessing poor performance of British aircraft against German aircraft with VDM constant-speed propellers did Fighter Command embark on a crash program to install propeller governors. In just 44 days about 300 Spitfires underwent 15 to 20 hour retrofit procedures, making them competitive with Bf 109s just in time for the Battle of Britain.
Propellers took a back seat to jet propulsion after WWII, but despite the popularity and efficiency of turbofans, propellers still fill important niches in general aviation, specialty military and civilian transport aircraft.
This is a book that is hard to put down. It relates the rich history of a specialized technology in an interesting and engaging manner. It is so meticulously documented that the notes alone are worth the book's price. Essays on sources acquaint the reader with archives and other information repositories that could facilitate further research, and an extensive index helps to rapidly locate technologies, organizations and people. Kinney's book excels on many levels and is a welcome addition to this reviewer's library.

John Leonard's exploration of the Rolls-Royce Heritage Trust, Allison Branch archives has led to another intriguing look into Allison history. While his last book, The Allison Engine Catalog, presented brief descriptions of Allison engines and products, and covered the period of 1915 - 2007, this one provides a substantially deeper treatment of the early years, 1915 - 1945.
Leonard begins with coverage of Jim Allison's personal life, interests and business ventures. He continues with biographical sketches of Jim's friends, business partners and key employees.
Next, Leonard devotes 39 pages to the history and evolution of the many Allison buildings built mostly in and around the town of Speedway, Indiana. Speedway was the brainchild of Carl Fisher, who, along with Jim Allison and others, had founded the Indianapolis Motor Speedway in 1906. Allison was also an investor in the town of Speedway, which provided housing for his employees. Leonard's coverage of the Allison Plants includes numerous maps and photographs.
Several key Allison development projects and products are covered in depth. These include Allison steel-backed bearings, Liberty engines and modifications, marine engines, the X-4520 (an air-cooled X-24 developed in conjunction with the U.S. Army Air Service Engineering Division), and an airship diesel.
Leonard devotes 24 pages to new Allison V-1710 material that has come to light since the publication of Dan Whitney's Vee's for Victory! This includes drawings, photographs, supercharger development concepts and performance charts. Similarly, new material is presented on the Allison V-3420. Leonard also covers Allison gearboxes, gearbox concepts, and many engine concepts that never entered production. Finally early Allison-built turbojets and turboprops are summarized.
This is not only an easy-to-read technical history, but also is a useful reference. I heartily recommend it to anyone interested in Allison history or the development of engines.

Paul Christiansen continues his excellent series on Westinghouse gas turbines in his latest book, which covers the J46 family. This is an in-depth account of how the Westinghouse Aviation Gas Turbine division attempted to bridge the gap between the U.S. Navy’s ever-changing requirements and the emerging technologies that might have met them.
The J46 was expected to have been a relatively straightforward development of the Westinghouse J34. However, the integration of an afterburner and all-new electronic control system, coupled with the Navy’s predilection for changing requirements and plans to use the J46 in a number of very different airframes, proved to be more than Westinghouse could accomplish within the aggressive schedule. Several aircraft projects that were to have used the J46 were cancelled and the Vought F7U-3, the only J46-powered aircraft to enter production, had a short service life, partially due to engine issues.
Christiansen begins with a review of the J34 program, which produced many developments and improvements that were central to the J46 program. He then describes elements of the J34-WE-22 and -38 that were to have been shared with the XJ46-WE-2 and ultimately covers procurement and development of the XJ46-WE-2 and -4. Three chapters cover XJ46 and J46-WE-8/A/B and -12/A/B development, production and service. Other chapters chronicle J46-WE-18 and XJ46-WE-1, -3, -5 and -7 development, J46 flight testing, and J46 improvement/growth programs. Christiansen’s Analysis and Conclusions chapter reiterates how the Navy’s indecision and focus on superfluous details added to the technical problems both the J46 and F7U-3 programs faced. Appendices provide engine ratings and specifications, operating limits, a (long) list of YJ46-WE-8A field service problems, and a list of surviving J46 examples.
With 925 citations from 204 sources (nearly all primary), this book, like its predecessor, provides valuable insight into early U.S. gas turbine development. Christiansen is hinting that a book on the early Westinghouse engines (19A, 19B, 9.5A, 9.5B, and 19XB2A, which became the J30) is in the works; this I shall anxiously await.

Thomas Hitchcock has produced a fantastic, large format, high paper quality, three pound, 208 page book about the German Ta 152 high altitude fighters developed late in WWII. The research and documentation are peerless, including 51 original Focke-Wulf drawings of the airframe and sub-assemblies, 29 photographs of the several types of engines used or proposed for the Ta 152 series of aircraft, and 21 engine drawings. There are four appendices detailing 1) camouflage and markings, 2) production, 3) specifications, weights, performance and equipment, and 4) pilot operating instructions.
Hitchcock has acquired first person descriptions of flying and fighting in the Ta 152, and masterfully traces its complicated development and its ultimate, limited entry into combat during the spring of 1945. There are also period and modern color photographs of the lone surviving Ta 152H-0 held unrestored in the collection of the Smithsonian National Air and Space Museum. With 180 photographs overall, 40 color photographs, 36 color illustrations, and 19 tables and charts, there is something for everybody, especially the technically-minded devotees of the Aircraft Engine Historical Society. I cannot say enough about the depth of subject detail, astounding research, excellence and clarity of writing, and physical quality of the book itself. At 36 cents per page, it seems expensive, but in my opinion, it is a bargain.

This book details the role that Detroit’s automobile manufacturers played in World War II materiel production. The auto companies made aircraft engines, propellers, complete aircraft, aircraft components, tracked vehicles, wheeled vehicles, and munitions. Being an aircraft engine enthusiast, I was particularly interested in the sections concerning aircraft engines and propellers.
Wright Aeronautical Corporation licensed two auto companies to make two models of their engines. The Studebaker Corporation produced the R-1820 for the B-17 and Dodge-Chicago manufactured the R-3350 for the B-29.
Pratt & Whitney licensed its engines to the following automobile companies: Ford (R-2800); Buick (R-1830); Chevrolet (R-1830, R-2800); Nash-Kelvinator (R-2800). Allison, a General Motors division, made aircraft engines before and during the war. Packard Motor Car Company built the Rolls-Royce Merlin liquid cooled V-12 engines.
The most impressive production was auto maker Nash-Kelvinator’s production of 158,134 Hamilton Standard propellers.
Also mentioned in Arsenal of Democracy were the manufacture of complete aircraft by three auto companies. Ford built B-24s at the Willow Run, Michigan and Waco-designed wood gliders in Iron Mountain, Michigan. Eastern Aircraft, a division of the General Motors Corporation, built Grumman Avenger torpedo bombers and Wildcat Fighters. Nash-Kelvinator completed 262 Sikorsky R-6 helicopters.
I was interested to read about two men who played a prominent role in World War II war production. William S. Knudsen had a long career as an auto industry executive, first with Ford and later with General Motors. He resigned his position as president of General Motors in 1940. Franklin Delano Roosevelt appointed him as Director of War Production. Albert Kahn was the foremost American industrial architect from the 1900s to the 1940s. Kahn’s architectural firm designed the massive 6,430,000 square foot floor space Dodge-Chicago B-29 engine plant. Albert Kahn also designed the Willow Run B-24 plant. It consisted of an L-shaped building with 4,734,617 square feet of floor space. Interesting enough, both Kahn and Knudsen were immigrants to America. Knudsen was born in Denmark; Kahn was born in Germany.
I did notice some misinformation in the section concerning Buick-built Pratt & Whitney engines. The author states that Buick built Pratt & Whitney R-2800s for the C-54 cargo plane. I have never seen any other reference that anything but Pratt & Whitney R-2000s powered C-54s.

Rotol was established in 1937 by the drive of Sir Roy Fedden of the Bristol Aeroplane Company. Fedden managed to convince Lord Hives of Rolls-Royce that it was imperative to establish a propeller company to compete with de Havilland as well as the American manufacturers Hamilton-Standard and Curtiss. Bristol and Rolls-Royce each contributed money and personnel to the endeavor, which was born at a time when standardization of the propeller/engine interface was being discussed. The great debate of hardwood versus magnesium versus aluminum (aluminium to the Brits) versus steel versus compressed wood composite propeller blades was raging. Engine horsepower along with aircraft performance was accelerating, and war clouds were gathering.
Stait develops wonderful personalities in his story, especially the imperial, but right-man-at-the-right-time for the job, Rotol Comptroller R. H. Coverly. The process of weaning Rotol off subsidies of money and the cherry picking of skilled manpower from the parent companies is discussed, and fascinating details of wages, mistakes, communists, the war, expansion, competition, and dealing with the British Ministries is all told in a wonderfully British manner. As time and technology progressed, additional product lines are discussed and launched with variable success. The pain of the immediate post-war adjustment to production and employment, the advent of the turboprop engine, the "limited" future of the propeller in the coming jet age, and corporate mergers are presented in a well-organized and pleasantly detailed manner.
The history of Rotol as penned by Dowty retiree Bruce Stait is an outstanding work full of personal insight, excellent research, refreshing technical detail, and a multitude of stories and anecdotes captured by the author from Rotol employees themselves. The book has 20 pages of black and white photographs and eight welcome appendices which include rates of pay, cost of propellers, the Rotol propeller numbering system, wood blade markings and construction details, and propeller design.
Readers with an interest in propellers will undoubtedly enjoy this history, but the richness in detail of both the times and the Rotol employees will delight readers with an interest in the 1937-1960 period of British history.
