Special Issue Information
Dear Colleagues,
The Guest Editors are inviting submissions to a Special Issue of Energies on the subject area of “Secondary Air Systems in Gas Turbines”. In order to increase the cycle efficiency and specific work output of gas turbines, the turbine entry temperature (TET) is raised beyond the metallurgical limit of the engine components. Consequently, bleed air is taken from the compressor stages and used to cool the turbine. The intricate cooling pathways, seals, and metering devices are collectively known as the secondary air system (SAS). Effective use of the SAS is paramount: superfluous use of bleed air results in an uncompetitive engine design, whereas insufficient or ineffective cooling has a detrimental effect on engine life.
The aim of the present Special Issue is to collate and disseminate the current state-of-the-art in SAS design. Contributions will be sought from the world’s leading research groups in this field.

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. Energies is an international peer-reviewed open access semimonthly 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 2600 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.
