Available in PDF, EPUB and Kindle. Book excerpt: Mathematical expressions are derived for the interference forces and moments acting on the tails of slender plane and cruciform wing-tail combinations of general plan form in steady straight flight at combined angles of attack and sideslip. The derivatives are made within the limitations of slender-body theory under the assumption that the vortex sheet leaves the wing as flat sheet and becomes fully rolled up ahead of the tail. The derived expressions are used to calculate the steady lifts, side forces, pitching moments, and rolling moments of the number of wing-tail combinations. The effects of changes in tail height, tail length, ratio of tail span to wing span, tail incidence, and tail thickness are calculated. The resulting curves, and particularly their nonlinearities, are discussed at some length in connection with static stability. In general, the most dramatic effects are noted when the vortices shed from the wing strike the tips of the tail trailing edge.

Nielsen and published by . This book was released on 1956 with total page 676 pages. Available in PDF, EPUB and Kindle. Book excerpt: The wing-body interference theory of NACA TN 2677 applied to symmetrical wings in combination with quasi-cylindrical bodies permits the direct calculation of pressure-distribution changes produced by body shape changes. This theory is used to determine the relative magnitued of the wave-drag reduction produced by changes in cylinder cross-sectional area and that produced changes in cross-sectional shape (without change in area). The body distortion is expressed as a Fourier series, and an integral equation is derived for the body shape for minimum drag for each Fourier component. Thus the wave-drag reductions for the various Fourier harmonics are independent and additive.

This book was released on 1971 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of predicting the induced roll phenomena associated with finned missiles at high angles of attack has been approached by examining the interaction between the body wake vortex system and the finned surfaces of the missile. The application of the classic Blasius moment integral to this problem permits the independent evaluation of each singularity in the flow field which may contribute to the moments. This method is applicable to missiles employing fin schemes of any geometry and is used herein to analyze the induced roll of a typical cruciform missile configuration. A computer program has been developed to generate numerical solutions utilizing those parameters which affect the magnitude and direction of the induced roll. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Aerodynamic interference between an aircraft and a store carried beneath its wing is investigated using the simplified physical model of a uniform wing of infinite span and a slender body of revolution positioned beneath the wing. The wing is represented by a vortex filament, the store by a distribution of sources and doublets along its axis of revolution, and potential flow is presumed to exist. The aerodynamic forces acting on the store while it is attached to the aircraft are computed using this model. The trajectory that the store follows after it is released is studied for mass, initial position relative to the wing, and initial angle of attack. If a store is symmetric and homogeneous, it appears to be unstable after release, and rapidly violates the small angle assumptions of the study. Several trajectories are computed, and show that the aerodynamic loads can be large enough to propel a store of considerable mass into the ai craft that released it.

This book was released on 1949 with total page 646 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aerodynamic forces and moments exerted on pitched and yawed wing-body combinations consisting of a slender body of revolution and a cruciform arrangement of thin wings have been investigated by two theoretical methods. One method, an extension of the slender wing-body theory of NACA TN No. 1662, makes possible the determination of simple closed expressions for the load distribution, of simple closed expressions for the load distribution, the forces, and the moments for slender cruciform-wing and body combinations in which the wings may be dissimilar plan form. The second method treats cruciform-wing and body combinations consisting of a body of revolution and identical wings of arbitrary aspect ratio and plan form. The results are valid at subsonic, transonic, and supersonic speeds.

Available in PDF, EPUB and Kindle. Book excerpt: Aerodynamics, the study of air motion around solid objects, allows us to understand and measure the dominating forces acting on aircrafts, buildings, bridges, automobiles, and other structures. The forces that result in an aircraft overcoming gravity and drag are called thrust and lift. Various parameters such as geometrical configurations of objects, as well as physical properties of air, which may be functions of position and time, affect those forces. This book covers some of the latest studies regarding the application of the principles of aerodynamics to the design of many different engineered objects. This book will be of interest to mechanical and aerospace engineering students, academics, and researchers who are looking for new insights into this fascinating branch of fluid mechanics.
