Westinghouse developed aviation gas turbine engines beginning in late 1941 and continued designing engines both for the United States Navy and the United States Air Corps into the 1950's. Considered a third tier producer in the aircraft engine industry, they were soon surpassed by the development of more satisfactory designs by their competition. All during their existence until they left the business in 1960, the company produced engine designs and studies. Many of these were strongly influenced by their access to Rolls Royce engineering methods, designs and patents. This is the first compilation of the company's jet engine designs and studies in the aviation field. It is a companion work to the author's detail development histories of many of the Westinghouse production engines. It reveals the many almost unknown advanced engines that were schemed and proposed before the company faded from the aviation jet engine industry.
