TLDR
In this article, a computational methodology of aerodynamic interaction between propeller and wing is described, and the influence of propeller model to wing is simulated as contribution of higher dynamic pressure and change of angle of attack behind the propeller.Abstract:
In this paper a computational methodology of aerodynamic interaction between propeller and wing is described. Presented work is focused on development of quick and accurate tool. Lifting line theory (LLT) with nonlinear airfoil characteristic is used to solve a finite span wing aerodynamic to predict downwash and lift distribution respectively. Blade element momentum theory (BEM) is used as a computational tool for estimating total thrust, torque, axial and tangential velocity distributions. Model of slipstream development is considered. Influence of propeller model to wing is simulated as contribution of higher dynamic pressure and change of angle of attack behind the propeller.read more

Applications of Modern Hydrodynamics to Aeronautics
TL;DR: In this article, an introduction to hydrodynamics is given, which is designed to give those who have not yet been actively concerned with this science such a grasp of the theoretical underlying principles that they can follow the subsequent developments.
On the elementary relation between pitch, slip, and propulsive efficiency
TL;DR: In this article, the authors examined the importance of reducing slip in airplane propellers and felt an exaggerated importance is attached to this supposition and felt that the increase in friction by an increase in propeller area or number of revolutions can't be discounted.

Computational Study of Propeller–Wing Aerodynamic Interaction
TL;DR: The results show the capability of Kestrel simulation tools for modeling and design of propellers and investigates their effects over aircraft during conceptual design in which no experimental or flight test data are available yet, which will lead to reducing the number of tests required later.
