S.P. : The Proceedings of the Symposium on Mechanics for Space Flight 1987}, month = {Mar}, note = {A statistical method is proposed to treat accelerated life test data conducted at several elevated temperatures for a sufficient number of commercially available Cu-water heat pipes to predict the operation life. The temperature distribution measurements periodically carried out yield both data sets soncerning the temperature drop and the gas column length as measures of non-condensible gas accumulation. The gas analysis with a mass spectrometer is also carried out to obtain the gas quantity data. A method of unified regression analysis to take account of the acceleration factor resulted from a number of elevated test temperatures is proposed to establish a method to predict the long-term performance degradation from life test data. The mutual correlations among three kinds of data sets are also discussed., 資料番号: SA0033592000}, pages = {87--98}, title = {A Statistical Treatment of Accelerated Life Test Data for Copper-Water Heat Pipes}, volume = {6}, year = {1988} }
