Abstract:

Results are presented of a study to examine the rel tio ships b acc racy and cos i m n our , cal ndar time and dollars, in deter ing this transient heat flow for two hypothetical re-entry vehicles. Accuracy and cost information were obtained for analytical methods h nd calculations, digital computers, differential analyzers, and passive el ment analogues and for experimental methods various size panels, half and full size vehicles, and vehicle c mpartments. Results are presented as curves of accuracy as a function of cost. A general heat transfer digital computer program provided the most accuracy for the least cost. The other computing techni ues rank in the following ord r differential analyzer, passive element analogue, and hand calculations. T HE DIFFERENTIAL ANALYZER IS THE BEST METHOD FOR PARAMETER STUDIES WHERE A LARGE NUMBER OF RUNS IS EXPECTED. Author
