Finite Span Wings in Compressible Flow
Author: E. A. Krasilʹshchikova
Publisher:
ISBN:
Category : Aerodynamics
Languages : en
Pages : 138
Book Description
Abstract: Equations are developed using the source distribution method for the velocity potential function and pressure on thin wings in steady and unsteady motion. Closed form solutions are given for harmonically oscillating wings of general plan form including the effect of the wing wake. Some useful examples are presented in an appendix for arrow, semielliptical, and hexagonal plan form wings. The paper is essentially a summary of previous work by the author.

Calculation of Unsteady Transonic Aerodynamics for Oscillating Wings with Thickness
Author: S. Y. Ruo
Publisher:
ISBN:
Category : Aerodynamics, Transonic
Languages : en
Pages : 60
Book Description
An analytical approach is presented to account for some of the nonlinear characteristics of the transonic flow equation for finite thickness wings undergoing harmonic oscillation at sonic flight speed in an inviscid, shock-free fluid. The thickness effect is accounted for in the analysis through use of the steady local Mach number distribution over the wing at its mean position by employing the local linearization concept and a coordinate transformation. Computed results are compared with that of the linearized theory and experiments. Based on the local linearization concept, an alternate formulation avoiding the limitations of the coordinate transformation method is presented.

Experimental Aerodynamic Derivatives of a Sinusoidally Oscillating Airfoil in Two-dimensional Flow
Author: Robert L. Halfman
Publisher:
ISBN:
Category : Aerofoils
Languages : en
Pages : 752
Book Description
Experimental measurements of the aerodynamic reactions on a symmetrical airfoil oscillating harmonically in a two-dimensional flow are presented and analyzed in this paper. Harmonic motions include pure pitch and pure translation, for several amplitudes and superimposed on an initial angle of attack, as well as combined pitch and translation. Considerable consistent data for pure pitch were obtained from a search of available reference material, and several definite Reynolds number effects are evident.
