Interpolating Subroutine for High Power System Design.
Abstract
The Aero Propulsion Laboratory is currently developing a computer-aided design program for high power airborne systems. An important part of this design program will be the feasibility study which was to be based on summary algorithms. These algorithms were to relate the weight and volume of each system component to the contributing operating parameters. This study first centers on the requirements for an interpolation scheme to form the summary algorithms. The scheme will need to work in at least four dimensions and produce accurate results over wide ranges. The advantages of the two possible interpolation approaches (algorithm development and direct interpolation) are described. The results of this comparison show clear advantages in the direct interpolation approach using stored data. The remainder of this study is a description and evaluation of the subroutine which was developed, INTERP. It has the flexibility to interpolate a data array with two or more independent variables and will output the values of any number of dependent variables. The routine also compensates for missing values in the known data array and issues an error message to the user when a test point beyond the data range is input. (Author)
