NOLFR - A Computer Program to Read Wind-Tunnel Free-Flight Data Film,

Abstract

A computer program was developed to control an automatic optical scanner in reading specialized wind-tunnel free-flight data film. In each frame, the program locates the model, a slender pointed cone, and calculates the attitude of the model centerline and the planar coordinates of the center of gravity relative to fixed fiducial marks. The program is written in FORTRAN and assembly language for the IBM 1800 computer interfaced with an automatic optical scanner. (Author)
