    Abstract

    In some problems of Aeronautics such as the analysis of pressure data obtained from the wind tunnel testing on wing models or the determination of tie boundary layer characteristics from a known pressure distribution on an aerofoil one encounters with the interpolation, differentiation and integration of a functvon (eg. pressure) given at unequal intervals. Techniques available in practice such as hand fairing, series of equivalent rectangles, least-square polynomial fits and cubic curve fits give crude results* This report presents a new method based on spline approximation which gives very accurate and reliable results compared with any of the methods available now. The method is programmed for the NAL sirius computer.
