An Approximate Theory of Airfoil Cascade in Subsonic Flow

Abstract

This paper deals with an approximate theory of airfoil cascades in subsonic flow. The theory is developed by the so-called "Interference Method" and the Prandtl-Glauert's approximate theory of airfoil in subsonic flow. The calculated results of some airfoil cascades coincide well with the ones calculated by the "Hodograph Method". The Inverse Problem is also discussed in this paper.
