Industrial Application of the Pratt & Whitney Aircraft J-57 630066

This paper tells of the changes made to the standard Aircraft J-57 turbojet engine in order to convert it to an industrial gas generator, problems encountered during the 8000 hr protoyype test, and changes made to solve these problems.
The author concludes that the modified J-57 is a fully acceptable industrial gas generator, and the same expectations are held for Pratt & Whitney Aircraft's modified J-75 and JT-12 gas generators that have also been placed in industrial use.
