The report estimates turbine engine parameter tradeoffs over time, using multiple regression analysis. Movement of the parameter tradeoff curve is defined as technological advance. The data base includes the first model of a given turbine engine to pass the model qualification test. The history of turbine engines strongly suggests that single parameter analysis cannot capture the richness of the development process. The rate of technological advance seems fairly constant over time. However, two major manufacturers have been ahead of the others in the level of technology. Comparison of Soviet and American equations revealed an early Soviet lead, reversed since the 1950s.
