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

The need to clean and low cost gas generator systems for the use to inflate the airbags in motor vehicles has greatly increased. Aiming to avoid the disadvantages of solid azide- and tetrazol-based gas generants, and combinations of high pressure inert gas with solid propellants to be adapted in current and near-future airbags, this investigation has been carried out to manage to apply water solutions of stabilized hydrogen peroxide from 55 to 60wt% in concentration to the combustors to be integrated in airbag module. There are some favorable properties with such a low concentration H2O2 solution: azeotropic behavior to suppress the freezing point lower than 233K, no hazard of causing the spontaneous explosion accident due to the self-accelerated decomposition during long time storage in confined vessel, low production cost and contribution to downsizing of the modules. First of all, however, it must be stressed that the decomposition products of H2O2 emitted from airbags into the environment are only clean oxygen, water haze and dry vapor.
This paper reports the achievement of successfully combusting simple H2O2 solution and hybrid propellant consisting of H2O2 solution of achievement in the practical application of the combustors loading simple H2O2 solution combined with pressurized oxygen to inflate airbags for passenger cars. In order to acquire the design data a series of investigation was conducted by means of heavy wall combustors to develop the starter for realizing the H2O2 decomposition at the designated time sequence, and developed a two stage injection method which pours the incandescent combustion products into H2O2 solution. At the event of collision the initiator should start, followed by firing the main booster. The initiator is the B/KNO3 pyrotechnic granules and pellets, catalyst powder and the booster is the pyrotechnics powder and highly energetic material. The total amount is approximately 3∼7g. The combustor is divided to a primary reaction chamber in which gas generant cartridge is placed and a secondary decomposition chamber putting the catalyst net for completing H2O2 decomposition. The experimental gas generator systems have proved to be capable of meeting the strict safety and environment standards and of corresponding to the time budget, which are requested in the deployment procedure items for 60 and 150 liter airbags at the temperature from 233 to 363K specified by Japanese Industrial Standards.
