The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.7 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 0.7 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00016 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.18 SJR: 0.313 SNIP: 0.6 CiteScore™:: 1.6 H-Index: 16

SINOPSIS

For the next generation of transportation systems, high reliability is required for credible and safe transportation. To carry out such a demand, a weight margin for a supplemental redundant system is necessary. At the same time, a more economical space transportation system is required. Since a required velocity increment is specified by a target orbit, the specific impulse of the booster stage has been increased and the use of an air-breathing engine has been studied. Since kinetic energy is proportional to a square of the velocity, the use of an air-breathing engine, e.g., the scramjet engine, in a hypersonic regime, is effective to attain such a large energy. Although the scramjet engine has superior performance, another engine is required to accelerate the vehicle from take-off to supersonic speed. When the vehicle with the scramjet increases to a higher altitude, a rocket engine is further required. The rocket-ramjet combined cycle engine, i.e., the rocket-based combined cycle engine (RBCC), is a combination of the rocket engine and the ramjet engine. The engine enhances an average specific impulse, compared to conventional rocket engines, and can operate from take-off to hypersonic speed. Japan Aerospace Exploration Agency (JAXA) has been studying the scramjet and the combined cycle engine. Herein, the recent activities of JAXA regarding them are presented.
