Abstract:

The problem of the interference of wing and propeller streams was investigated. The assumptions in classical analysis were critically examined. The importance of the nonuniformity and of the finite thickness of the propeller streams on the sectional aerodynamic characteristics of the wing were substantiated. Numerical programs were developed to carry out the two-dimensional sectional analysis of an airfoil in a nonuniform parallel stream. The classical analysis for wing and a single propeller was modified by the use of sectional analysis from the numerical program. For a wing and multipropellers, a new systematic scheme was developed.
