J E Fuller: 1173. Metrics in Aerospace. 1977.



This paper reviews the US metric requirements, current Aerospace status and direction and steps toward implementation. It describes the organizations involved in metrication of standards, along with SAWE’s current involvement with them. Recommendations for SAWE action are given along with some of the details associated with them. Mass versus weight is explained and a sample of familiar English System parameters with their metric equivalents is given. Viewgraphs showing the effect of metric standards on engineering drawings are shown. Conclusions are that metric conversion will take place in the Aerospace Industry; that creation of and revision to standards is the first step; that we should only learn what we need; that the complete design of a metric air vehicle is still several years away.
