Catalog performance data can reveal hidden design features

摘要

Once you know how, it is possible to get at buried design data to appraise the level of design technology or validate guarantee performance test results. Dr. Hans Wettstein, international consultant to gas turbine owner-operators, has come up with an interesting forensic approach to evaluating the internal design performance of new and old gas turbine models. Generally, original equipment manufacturers readily quote guaranteed performance data. But they do not like to tell you about associated subsystem design performance.
