A computer program is presented that calculates the annular airfoil shape from a given pressure distribution. A brief review of the theory of the inverse problem of the annular airfoil is also presented. The distortion of the duct shape by the presence of an axisymmetric body or a propeller may be taken into consideration. Calculations show that for a given pressure distribution, the propeller loading and location affect the duct shape.
