Abstract
This paper was presented at the Twentieth National Conference of the Society of Aeronautical Weight Engineers at Akron, Ohio, May 15 – 18, 1961. Data reduction, whether the solution of specific equation for given test items, or the accumulation of data from statistical or dynamic processes, is a problem with which all in the aeronautical and allied sciences are particularly concerned. As a means of mitigating this problem, where weight data is concerned, this paper argues the case for automatic digital recording and processing of weight parameters. The more directly that weight are converted to digital form and entered into automatic processing, the higher are system accuracies. Two specific problems are cited for illustrative purposes. One is a missile motor weight and center of gravity determination in three coordinates and the other, a mass flow measuring system for volumetric meter calibration. Other processes are equally enhanced, such as digital control of automatic batch plants, and continuous feeder-weigh systems. All of these are currently of significant interest to the engineer working on missile and space programs.
