Download or read book Some Theoretical Characteristics of Trapezoidal Wings in Supersonic Flow and a Comparison of Several Wing flap Combinations written by Robert O. Piland and published by . This book was released on 1951 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The theoretical lift and pitching moment due to angle of attack and pitching and the lateral force and yawing moment due to rolling of a trapezoidal wing are derived. The equations are applicable when the inboard Mach line from a leading-edge tip intersects the trailing edge and the outboard Mach line lies ahead of the side edge. When the side edges are raked in, the former condition is sufficient. A comparison based on theoretical expressions of the lift and rolling effectiveness for half-delta tip (point forward) and trailing-edge flaps on various plan forms is made.

Available in PDF, EPUB and Kindle. Book excerpt: Fretting corrosion was concluded to be caused by the removal of finely divided and apparently virgin material due to inherent forces and that its primary reaction is independent of of vibratory motion or high sliding speeds. Fretting corrosion occurred to clean nonmetals and metals readily and glass microscope slides and steel balls provided an excellent method for visual studies.
Download or read book The Spanwise Distribution of Lift for Minimum Induced Drag of Wings Having a Given Lift and a Given Bending Moment written by Robert T. Jones and published by . This book was released on 1950 with total page 708 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of the minimum induced drag of wings having a given lift and a given span is extended to include cases in which the bending moment to be supported by the wing is also given. Expressions for the spanwise load distribution and the minimum drag in terms of the lateral position of the load centroid are given. The results show a 15-percent reduction of the induced drag with a 15-percent increase in span over that for an elliptic loading having the same total lift and bending moment.
Download or read book Application of the Laplace Transformation to the Solution of the Lateral and Longitudinal Stability Equations written by Andrew Gustav Mokrzycki and published by . This book was released on 1950 with total page 698 pages. Available in PDF, EPUB and Kindle. Book excerpt: The application of the Laplace transformation to the solution of the lateral and longitudinal stability equations is presented. The expressions for the time history of the motion in response to a sinusoidal control motion are derived for the general case in which the initial conditions, initial displacements and initial velocities, are assumed different from zero. Some illustrative examples of the application of the Laplace transform to ordinary linear differential equations with constant coefficients and a number example of a specific problem are presented in appendixes.
Download or read book The Effects of Sideslip Aspect Ratio and Mach Number on the Lift and Pitching Moment of Triangular Trapezoidal and Related Plan Forms in Supersonic Flow written by Arthur L. Jones and published by . This book was released on 1949 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: The variations of lift and pitching moment with sideslip in supersonic flow have been calculated for a representative gorup of plan forms. The variations of lift and pitching moment with aspect ratio and Mach number at zero sideslip were also investigated. The analysis was based on linearized potential theory and was applied to triangular, trapezoidal, rectangular, and swept-back plan forms without dihedral.
Download or read book Stability and Control of Airplanes and Helicopters written by Edward Seckel and published by Academic Press. This book was released on 2014-05-10 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stability and Control of Airplanes and Helicopters deals with aircraft flying qualities that determine the stability and control of airplanes and helicopters. It includes problems based on real aircraft, selected to represent the gamut from simple to complicated, and from conventional utility designs to futuristic research types. Many of these problems involve comparison of theory and experiment to demonstrate their mutual relationship. Comprised of 25 chapters, this book begins with a discussion on the aerodynamics of the component parts related to the lift and moment characteristics of an airplane, including wings and associated accessories; bodies such as fuselages, nacelles, and tip tanks; and control surfaces. The reader is then introduced to some mathematical techniques for linear differential equations; steady flight at different speeds; and stick force and control-free stability. Subsequent chapters focus on flaps and high-lift devices; power and compressibility effects; and the manner in which the aircraft responds to the application of control. Aeroelasticity and longitudinal equations of motion are also examined. This monograph is intended for undergraduate and graduate students taking modern engineering courses.
