Progress in Aerospace Sciences

Progress in Aerospace Sciences is an international review journal designed to be of broad interest and use to all those concerned with research in aerospace sciences and their applications in research establishments, industry and universities. The journal is devoted primarily to the publication of specially commissioned review articles designed to bring together under one cover current advances in the ever-broadening field of aerospace sciences. No artificial limits are imposed on the length of papers and authors are encouraged to provide specialist readers with an orderly and concise summary of recent work, including sufficient detail for more general aerospace readers to be informed of recent developments in fields other than their own. The coverage of the journal includes timely reviews in aeronautics and astronautics, especially in important aerospace areas such as aero- and gas dynamics, aero-and space structures, flight mechanics of air and space vehicles, materials, vibrations, aeroelasticity, acoustics, aero- and space propulsion, avionics, and occasionally some related areas as well, such as wind engineering and hydrodynamics. "While the emphasis is on reviews of current developments, papers providing historical perspectives on important past developments and their pioneers are also welcome. Occasionally, the journal also publishes reviews of new books on aerospace topics."

Quartiles

The set of journals have been ranked according to their SJR and divided into four equal groups, four quartiles. Q1 (green) comprises the quarter of the journals with the highest values, Q2 (yellow) the second highest values, Q3 (orange) the third highest values and Q4 (red) the lowest values.

SJR

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.

Cites per Doc

Evolution of the number of total citation per document and external citation per document (i.e. journal self-citations removed) received by a journal's published documents during the three previous years. External citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal’s documents.
