Development Histories 

About the Author:  The author is a former Vietnam era U.S. Army helicopter pilot with a lifelong interest in aviation and aircraft engines. He has spent many years researching the technical development details of Westinghouse axial turbojets. His first volume on the Westinghouse J40 has been extremely well received. Retired from a long career with IBM, he lives in Olney, MD with his wife.

    The Early Westinghouse axial turbojets up to the J34 - the early success that led them and the U. S. Navy to believe they knew                    what they were doing....

NEW ! !

Drawing almost exclusively from primary sources, this volume details the development history of each of the many Westinghouse J40 engine models. Long buried in various archives, the technical struggles of Westinghouse to achieve success are at last revealed in detail. The J40 engine program occurred at a time when engine manufacturers the world over were endeavoring to push engine thrusts and efficiencies beyond the initial achievements in World War II and the years immediately following. Westinghouse failed to make timely investments in resources and research until it was too late to affect the outcome of the program. The failure of the higher powered J40 models that the U.S. Navy counted on for multiple airframe projects seriously delayed major programs, resulting in Congressional censure. Focusing on the technical aspects of the engines, this volume clarifies and corrects the many errors published over the years regarding these engines. The volume includes many informative illustrations and charts regarding the construction and operational details for the various models.Type your paragraph here.

Specialists in offering detailed histories of the various Westinghouse Aviation Gas Turbine Division's engines, correcting the many errors published in the past, filling in the poorly documented details of these engines, particularly the much maligned and publicized J40 failure and the inadequately developed J46. The ongoing effort to offer a full set of histories for all of the planned and actually built Westinghouse engines continues.

The Westinghouse J46 Axial Turbojet Family, Development History and Technical Profiles,

Paul Christiansen, November 2016.   

The first volume in the series dealt with the Westinghouse J40. This volume details the development history of the J46 engine, beginning with the developments of the J34 engine that ended up in the initial J46. The unexpected and prolonged technical struggles of Westinghouse to bring the J46 to production status are detailed, along with the development histories of forgotten variants planned or developed for cancelled airframe projects. The J46 engine program resulted when The U.S. Navy Bureau of Aeronautics identified a need for more power than the existing J34 could produce. Expecting to capitalize on the outcome of BuAer’s extensive J34 improvement investments, Westinghouse planned the new engine as yet another stretch of the J34 design with an all new electronic control system that for the first time integrated an afterburner. The development failure of the initial control system, and recurring mechanical problems led to late production and the delay of the introduction of the Vought’s F7U-3 Cutlass into service. Itself over-weight and plagued with problems, this aircraft was called “gutless”. The author offers interesting insights into contributing causes. With the withdrawal of the F7U-3 from service, both the J46 and its planned, almost unknown, successors quickly sank from view. Focusing on the technical aspects of the engine’s development, primary sources were used almost exclusively. Contains 74 illustrations and numerous charts regarding the construction, performance, and operational details for the various models, many of which are almost unknown to the public.
