This book was released on 1968 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes PLANAR, a data-reduction program for wind tunnel free-flight tests which utilizes data from a single plane. The program calculates moment, force and, in the case of a spinning model, Magnus coefficients. The program is written for an IBM 7090 computer operating under the IBSYS monitor. The mathematical formulation of the problem and the computer program are presented. The program description includes a FORTRAN listing and instructions for its use. (Author).
