Unsteady Supersonic Cascade Theory Including Nonlinear Thickness Effects.

Abstract

Several problems are treated which arise in the study of generalized airforces in unsteady supersonic cascades having subsonic axial velocity. The finite cascade of oscillating wedges involving thickness is first solved numerically. There is some indication that thickness effects are reduced by cascading. Next, the finite cascade of oscillating flat plates is solved analytically, to the third power of oscillation frequency. For comparison with the finite cascade, there is presented finally an elementary periodic solution for the infinite cascade. A simple relationship between the two basic cascade models is developed.
