Outline of Final Research Achievements |
ISO11227 was published on September 15, 2012, in which hypervelocity impact test procedure on ejecta is specified in the case that small space debris impacts space structures. Around September 2017, systematic review of ISO11227 will start. A purpose of this study is wide spread of ISO11227 as well as oblique impact experiments by considering addition of oblique impact set-up to ISO11227 at this systematic review phase. In section 6.5 of ISO11227, oblique impact tests are recommended at the impact angle of 15, 30, 45, 60 and 75 degree. In the oblique impact tests, ejecta will be also generated and emitted in oblique direction. So then configuration of target and witness plate is important. In this study, two configurations of oblique impact angles smaller than 30 degree and larger than 45 degree are proposed. These configurations will be added to the current ISO11227 after more than two third P-members support this modification under discussion at ISO/TC20/SC14 meeting.
