Bearbeiten von „Instrumentation Lab Gap Matrix“

== Description ==

In order to highlight the research priorities in terms of Gas Turbine Instrumentation Development, [http://www.piwg.org PIWG] on the US side and [https://www.evi-gti.eu 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.

== Structure ==

== Aerodynamics and Performance ==
