Download or read book Methods of Calculating Aerodynamic Loads on Aircraft Structures Part Iii Effects of Engines Stores and Wing tail Interference written by David C. Chou and published by . This book was released on 1966 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods are presented for calculating aerodynamic interference loads on aircraft components. The report treats wing-tail interference, effects of stores and effects of engines. In the first part, a simple method is proposed for calculating the load distribution on the tail in the presence of wing and fuselage. Next, a modified image method is described for calculating interference loads of wing-body-store combinations. The last part deals with the aerodynamic interference effects on lifting surfaces in the presence of either a propeller slipstream or a jet slipstream. General effects of small flow disturbances on aircraft loads are also considered briefly. (Author).

This book was released on 1966 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods are proposed for calculating the distribution of aerodynamic loads due to mutual interference effects between wings and bodies. The methods fall into two ranges of applicability: linear, and nonlinear, with angle of attack. Applicability of the linear loads methods to aeroelastic calculations is discussed. A computer program is presented which may be used to calculate interference loads at subsonic Mach numbers on a configuration consisting of (1) a body of any varying elliptic cross section and camber distribution, and (2) a wing with straight leading and trailing edges of any sweep angle, twist distribution, and camber distribution, located above or below the body centerline. Extension to the supersonic case is indicated. Generally good agreement with experimental data is found. Nonlinear wing-body interference loads are also considered. Several possible methods of representing the separated flow about a wing-body combination are proposed, and analyzed by the slender body theory. Numerical procedures are outlined, and some comparisons with experimental data are made.

This book was released on 1966 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method is presented for analysis of the nonlinear aerodynamics of slender configurations with vortex separation. Primary emphasis is on the nonlinear component of the aerodynamic characteristics. The theory is intended to be mathematically tenable yet give results of acceptable accuracy. A technique for analyzing the nonlinear aeroelastic problem is given followed by a method for obtaining the nonlinear aerodynamics of wings, bodies, and their combinations. Comparisons with experiment are provided. The experimental comparisons with the wing results indicate that the theory overestimates the nonlinear forces at high angles of attack. The results indicate directions for further research. (Author).

This book was released on 1953 with total page 704 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method for computing the steady-state span load distribution on an elastic airplane wing for specified airplane weights and load factors is given. The method is based on a modification of the Weissinger L-method and applies at subcritical Mach numbers. It includes the effects of external stores and fuselage on the spanwise loading. Modifications are outlined for treating tail-boom and tailless airplane configurations and for calculating the divergence dynamic pressure of a swept wing with a large external store. A method is also outlined for reducing wind-tunnel data to obtain effective aerodynamic coefficients which are free of model flexibility effects. The effects of Mach number can readily be evaluated from the aerodynamic coefficients thus obtained.

This book was released on 2012-12-06 with total page 715 pages. Available in PDF, EPUB and Kindle. Book excerpt: The basic partial differential equations for the stresses and displacements in clas sical three dimensional elasticity theory can be set up in three ways: (1) to solve for the displacements first and then the stresses; (2) to solve for the stresses first and then the displacements; and (3) to solve for both stresses and displacements simultaneously. These three methods are identified in the literature as (1) the displacement method, (2) the stress or force method, and (3) the combined or mixed method. Closed form solutions of the partial differential equations with their complicated boundary conditions for any of these three methods have been obtained only in special cases. In order to obtain solutions, various special methods have been developed to determine the stresses and displacements in structures. The equations have been reduced to two and one dimensional forms for plates, beams, and trusses. By neglecting the local effects at the edges and ends, satisfactory solutions can be obtained for many case~. The procedures for reducing the three dimensional equations to two and one dimensional equations are described in Chapter 1, Volume 1, where the various approximations are pointed out.
