NASA/TM-78627, NASA TECHNICAL MEMORANDUM 78627, COMPUTER PROGRAM TO PREPARE AIRFOIL CHARACTERISTIC DATA FOR USE IN HELICOPTER PERFORMANCE CALCULATIONS (01 DEC 1977)., A computer program developed to prepare wind tunnel generated airfoil data for input into helicopter performance prediction programs is described. The program provides for numerically cross plotting the data, plotting the data, and tabulating and punching the tabulated result into computer cards for use in the rotorcraft flight simulation model.
