A preliminary study identified the pivoted-pad bearing as most nearly meeting the requirements of the proposed application. Initial tests, using water as the lubricant, revealed the formation of an unusual wear pattern on the pad corners at high speeds (8000-24,000 rpm). The problem was solved with the development of a method of relieving the pad edges to introduce and maintain the lubricant film. Thereafter, extended tests at speeds up to 26,000 rpm proved the bearing could be operated under the proposed conditions. The bearing configuration was then operated successfully to 12,000 rpm in potassium.","PeriodicalId":13050,"journal":{"name":"IEEE Transactions on Aerospace","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1965-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78448564","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}

The object is size and weight reduction and this is accomplished at the expense of bandwidth and/or efficiency. The characteristics of the rectangular cavity slot antenna are analyzed and compared with experimental data. The operating frequency may be shifted by magnetic bias. Loading the spiral and log conical antennas lowers the low frequency limit by a factor of two or three. Data are presented on the temperature sensitivity of ferrite materials for aerospace antennas.","PeriodicalId":13050,"journal":{"name":"IEEE Transactions on Aerospace","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1965-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78138347","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}

Because of the complex geometries and the large number of parameters involved, the solution to this general problem has long been regarded as too complex for direct solution. It has been shown that an equation may be greatly simplified and the number of parameters reduced to eight important ones so that the problem can be programmed for solution by a computer. The program yields temperature distributions as a function of both space and time and for time periods appropriate to the all-fire and the no-fire test conditions, i.e., milliseconds or five minutes. The solutions of the equation have been checked by over 400 firings with various header geometries, materials, and firing currents and found to be quite accurate. The solutions allow one to design ordnance hardware to have a wide range of all-fire characteristics for any designated no-fire characteristic. They also make it possible to predict the changes in ordnance design necessary to increase the no-fire characteristic from present one watt levels to 2, 5, or 10 watt no-fire levels.","PeriodicalId":13050,"journal":{"name":"IEEE Transactions on Aerospace","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1965-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78618112","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}

The non-linear equation, similar to Poisson's equation, is transformed into a partial difference equation. The magnetic induction is found at discrete points in the cross section of the machine. A new relaxation procedure, accelerated greatly by the use of a new physical method of adjusting the vector potential between two successive iterations, is used. The method is shown for an aerospace synchronous generator. Calculated and test results of the no-load characteristic agree quite well.
