Therefore the concentration of the residual oxygen and hydrogen from leaks in the cryogenic weigh environmental bags must be known at all times during the cryogenic weigh. Hydrogen and oxygen detectors will provide the optimum method for maintaining safe conditions. Hydrogen properties and safe mixtures are reviewed. The method selected to analyze the oxygen content is discussed. The selection, development, and testing of a hydrogen detector system is examined.","PeriodicalId":13050,"journal":{"name":"IEEE Transactions on Aerospace","volume":"297 1","pages":"167-172"},"PeriodicalIF":0.0,"publicationDate":"1965-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89007919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By means of an all solid-state cycloconverter type frequency changer power is supplied to the motor at a controlled frequency and voltage such that the motor is operated at controlled slip in a closed feedback system. In this loop the torque (and therefore, speed) can be instantaneously controlled. A low power level signal which varies the motor slip frequency is the controlling variable. The application of this concept to aerospace drives is discussed with particular attention given to servo-controlled antenna drive systems.","PeriodicalId":13050,"journal":{"name":"IEEE Transactions on Aerospace","volume":"10 1","pages":"93-97"},"PeriodicalIF":0.0,"publicationDate":"1965-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73704766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A detailed analysis of the generator is made using Park's equations. This analysis results in a mathematical model which is quite easily handled by a digital computer. A single time constant transfer function is used for the exciter-rectifier which has proved sufficiently accurate. The generator analysis could be extended to the exciter and rectifier equations derived in Reference 3 used to obtain better accuracy if sufficient exciter-rectifier data is available. The regulator transfer function is a ratio of polynomials with limits and constants furnished by the designer. The purpose of this paper is to present the detailed generator analysis and briefly discuss the methods of representing other system elements and the computer program used for problem solution.","PeriodicalId":13050,"journal":{"name":"IEEE Transactions on Aerospace","volume":"3 1","pages":"107-120"},"PeriodicalIF":0.0,"publicationDate":"1965-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80263463","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
