Numerical determination of indicial lift and moment functions for a two-dimensional sinking and pitching airfoil at Mach numbers 0.5 and 0.6

Bernard Mazelsky, Joseph A. Drischler
Jul 1952

The indicial lift and moment functions are determined approximately for sinking and pitching motion at Mach numbers M of 0.5 and 0.6. These functions are determined from a knowledge of the existing oscillatory coefficients at the low reduced frequencies and from approximate expressions of these coefficients at the high reduced frequencies.
