Computer Optimization of Hydraulic System Pressure for Development and Qualification Testing
A computer program has been developed to optimize hydraulic pressure system selection for use in the structural testing of aeronautical vehicles. This program will select the minimal number of pressure systems, using available hydraulic cylinders, to match all the simulated flight loads which are applied during a test. Programs were written for Fortran and Advanced Basic language users of the IBM 360/67 time-sharing system or the Varian 620/i stand-alone system. Various options are present in the programs to adjust for unique testing conditions. Since the number of pressure system combinations for large-scale testing can be astronomical, this program has eliminated what was formerly a frustrating, time-consuming, and highly subjective task.
