It may seem brash to claim that materials engineering has been the driver of gas turbine evolution, but the reality is that theory and design conceptualization occurred early in turbine history.
The early twentieth century saw rapid developments in many engineering fields as the theory of prior decades came to harvest.
Virtually every engineering operation had to be reinvented, from ensuring the purity of the alloys to the purity of the water used to prepare skin panels for welding [8].
IHPTET provided a coordinated effort between government and industry gas turbine science and engineering research.
