Impact Factor

Impact Factor is one of several quantitative tools generated for journals using Thomson Reuters’ Journal Citation Reports (JCR).

The impact factor of a journal is calculated by dividing the number of current-year citations to the articles published in that journal during the previous two years. Within JCR, journals are organized by subject listings so that publications are viewed within the context of their specific fields.

AIAA’s journals with the exception of the Journal of Thermophysics and Heat Transfer (JTHT) are ranked in the Engineering, Aerospace Sciences category. JTHT is ranked in the Engineering, Mechanical category and the Thermodynamics category. The Journal of Guidance, Control, and Dynamics also is ranked within the Instruments and Instrumentation category.

Journal impact factor is a useful tool for evaluating journals, but it should be used in an informed manner. Citation frequencies for individual articles vary greatly and a journal’s ranking is not indicative of the quality of all articles within the journal. It is also generally understood that a journal’s impact factor should not be used to assess the quality of work by a particular researcher or institution.
