Selected Papers from the 10th EVI-GTI International Conference on Gas Turbine Instrumentation

Dear Colleagues,

The European Virtual Institute for Gas Turbine Instrumentation (EVI-GTI) was founded in 2002 through the European Union’s Competitive and Sustainable Growth (GROWTH) program. Since 2005, the EVI-GTI has been a non-profit association. The Board, the membership, and the attendees represent basically all European turbomachinery OEMs, a broad variety of sensor and instrumentation vendors, and many universities and research institutes. There are more than 200 registered members of the EVI-GTI community. EVI-GTI is the largest association for gas turbine instrumentation in Europe.

EVI-GTI aims to facilitate improvements in Gas Turbine Instrumentation technology for control, monitoring, and testing by sharing OEM and user requirements and emerging solutions from the research sector and supply chain businesses. You can find our vision here.

EVI-GTI has, together with the Propulsion Instrumentation Working Group (PIWG) in the U.S., developed the Instrumentation Lap Gap Matrix (LGM) by analyzing the technology readiness of various technologies for sensors, probes, and instrumentation. The LGM shows which technologies are currently satisfactory, which are currently not available but can be worked around, and which are not available today and prevent the further development of gas turbine engines (e.g., to higher efficiencies).

The EVI-GTI International Gas Turbine Instrumentation Conference is an event that started in 2004, initially being a yearly conference in Europe. From 2006 onwards, it was organized every two years. Every other year, there is a transatlantic Joint EVI-GTI/PIWG Conference which takes place alternately in the U.S. and in Europe. The EVI-GTI Conferences are focused on promoting and disseminating new developments, and therefore presenters need to submit only a technical presentation rather than a full paper.

Since 2019, EVI-GTI has also been associated with EUROTURBO and has published its first Special Issue in the International Journal for Turbomachinery Propulsion and Power embodying the best papers from the 9th EVI-GTI Conference in Graz, Austria.

The 10th EVI-GTI Conference was structured into five sessions that covered topics related to instrumentation and measurement in (hot) engine parts.

The sessions were as follows:

• New Sensors Developments I-III;
• Engine Validation Instrumentation and Testing;
• Optical Methods I-II;
• Test Facilities;
• Test Facilities and Validation Measurement I-II.

Aside from the presentations and the key notes, “elevator pitch” sessions were held where the participants could introduce their work within 4 minutes without a formal presentation.

Almost 30 technical presentations were given, either as “presentation only” or as full-paper contributions. The best papers from the conference, corresponding to the IJTPP scope, are collected in this Special Issue.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Turbomachinery, Propulsion and Power is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
