The present report is concerned with the problem of the oscillating airfoil of finite span, within the frame of the linearized lifting surface theory. The aim of this study is the development of a theory which incorporates simultaneously the effects of three-dimensionality of the flow and of compressibility of the fluid. As an exact solution of this problem, even within the limitations of the linearized theory, presents very great difficulties, it is worth while to work toward an approximate theory which is valid provided the aspect ratio of the lifting surface is not too small.

As part of an investigation of flows around and forces on an oscillating finite wing in subsonic compressible flow, the exact double integrals occurring in the theoretical formulation of the three-dimensional nonstationary aerodynamic forces have previously been reduced to single integrals over the range of either one of the two independent variables. The present report describes a method for solving the resultant three-dimensional problem based on a generalization of approximate methods for solving two-dimensional problems. It is shown that the calculation of three-dimensional corrections to the two-dimensional integral equation for spanwise variation of circulation, provided tabulated values for the kernal of the integral equation are available.

Theoretical And Experimental Investigation Of The Effect Of Tunnel Walls On The Forces On An Oscillating Airfoil In Two Dimensional Subsonic Compressible Flow written by Harry L. Runyan and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 1955 with Aerodynamic load categories.
This paper presents a theoretical and experimental investigation of the effect of wind-tunnel walls on the air forces on an oscillating wing in two-dimensional subsonic compressible flow. A method of solving an integral equation which relates the downwash on a wing to the unknown loading is given, and some comparisons are made between the theoretical results and the experimental results. A resonance condition, which was predicted by theory in a previous report (NACA Rep. 1150), is shown experimentally to exist. In addition, application of the analysis is made to a number of examples in order to illustrate the influence of walls due to variations in frequency of oscillation, Mach number, and ratio of tunnel height to wing semichord.

This paper presents propeller characteristics for two propellers that differ only in inboard pitch distribution. The forward Mach number range extended to 0.062 and the blade-angle range was from 20 to 55 degrees. Section thrust-coefficient data are also presented to afford a more detailed analysis of the effects of modifying the pitch distribution of the inboard sections of a propeller.
