Numerical Examples and Conclusions Figures 1 and 2 illustrate typical results for two cascade configurations: a low-solidity cascade with no Mach wave reflections (Fig. 1), and Verdon's cascade A (Fig. 2). Unsteady lift and moment amplitudes are calculated by the uniformly valid formulas, Eqs. (22) and (23), and Eqs. (1821), and compared to previously obtained (nonuniform) approximations as well as the full unsteady solution. Note that the nonuniform approximation is actually quite good for cascade A, except for the range or2 <a<360 + 30 deg. It breaks down surprisingly quickly, however, for the lowsolidity cascade, for which the improvements obtained by using the uniformly valid approximation are most apparent.
