Test of a 100 K.W. De Laval Steam Turbine with an Introduction on the Principles of Design: Report circa 1920

http://www.lib.ncsu.edu/findingaids/mss00090

This 35-page report is a handwritten history and evaluation of the De Laval reaction turbine. It includes 11 diagrams, including rotor [design] and buckets, bucket details, a heat chart showing friction losses, a section of the nozzle, theoretical and actual velocity diagrams, the design of the bucket, governor details, the reducing gearing, the standard machine, and a chart showing the results of the tests conducted. While the author of this report is not known, it may have been created by John William Cox, who received his bachelor's degree in civil engineering from North Carolina College of Agriculture and Mechanic Arts in 1915. Cox also received a master's degree in civil engineering. from the college in 1921. Carl Gustaf Patrik de Laval (1845 - 1913) was a Swedish engineer and inventor who made important contributions to the design of steam turbines and dairy machinery. In the 1880s he built a small steam turbine turned by jets of steam, and in 1890 added a nozzle to increase the speed of the steam entering the turbine. De Laval's innovations are used today in rocket design and reduction gearing.
