Instrumentation Lab Gap Matrix

Description

In order to highlight the research priorities in terms of Gas Turbine Instrumentation Development, PIWG on the US side and EVI-GTI on the EU side have issued a Lab Gap Matrix. A first EVI-GTI version was released in 2004, then updated in 2009, containing measured quantities on one axis mapped against engine location / working environment on the other axis.

Measurement types were structured as follows and after a voting process among OEM’s, each area was highlighted in green, yellow or red depending on their level of maturity or even availability.
