INTRODUCTION … pg. 41 of 564
The objective of this report is to provide a comparison between performance prediction and test results for horizontal axis wind turbines. This report covers the AERO program in two versions (FORTRAN and Hewlett-Packard 41-C) and the comparison between predicted and measured performance of the ENERTECH 1500 and UTRC 1/3 scale wind turbines.

... I extracted the HP-41C program pages, cut them into strips and passed them through OCR and manually edited the conversion errors I could see.
I have not tested the resulting program - there may still be some typos or incorrect line numbering.
